Headline: A short phrase or sentence describing what you expect the user to see on that page. Headlines are usually written in title case (the first letter of every word capitalized) rather than sentence case (the first letter of each sentence capitalized).

Hidden Text: Text that is deliberately made to be invisible by changing the color of the font or placing it behind an image. Hidden text is often stuffed with keywords to influence search engine rankings. This practice is illegal and can penalize your website or ban you from search engines.

Hilltop Algorithm: A method by which the relevance of a web page is determined by evaluating its inbound links. Any web page with a link from another highly-ranked page will also be considered valuable, as this indicates that the content on the linked page is relevant and vital.

HITS Algorithm: an algorithm used to determine the relative importance of certain websites within a network. HITS stands for Hyperlink-Induced Topic Search and searches for hubs (pages that have many inbound links) and authorities (pages that are linked to by many hubs).

Home Page: The main page of a website.

Hreflang: This attribute helps indicate to search engines that a page is intended for users in a specific geographic location or speaking a particular language. This attribute helps ensure that the right searcher sees the correct version of your site, and it also helps search engines return the most relevant sites in their results.

Htaccess File: A configuration file found on Apache servers. It controls permissions, redirects, and other functions. These files can block bots and crawlers from accessing certain parts of your site.

Hypertext Markup Language (HTML): This language is used to structure and present the World Wide Web content. It’s also the core technology used for creating web pages and web applications. Its primary function is to organize text and images into a structure displayed in a web browser.

HyperLink: A hyperlink is a clickable link on a page. They can be internal, which takes visitors to another page on your website, or external, which takes visitors to an entirely different website.

HTTP: is the communications protocol used between browsers and websites. It stands for HyperText Transfer Protocol, and it enables a web browser to send requests (to load a page, for example) and receive responses from the server that hosts the website you’re interacting with.

HTTPS: is an encrypted version of HTTP that utilizes Transport Layer Security (TLS). The “S” stands for secure. HTTPS is used on sensitive sites where information such as credit card numbers or other personal data need to be protected.

Hub Page: A hub page is a page on a website that serves as a starting point or destination for the other pages on the site. It is generally an umbrella topic where the reader can find relevant links to various issues.


Glossary Letter I

Image Carousels: Feature that rotates images in a designated spot on a website’s homepage or landing page. Carousels can help draw users’ attention and direct their eyes to specific content on the site or provide a quick overview of information.

Image Compression: The process by which an image’s file size is decreased without compromising its quality. Images can take up much space on a webpage, making loading slower for users, so image compression shrinks the file size without changing how it looks so that it takes up less space and loads more quickly.

Image Sitemap: An XML document that helps search engines index the images on your site. It gives search engines extra information about each image, such as where it should be listed in the search.

Impressions: The number of times a page appears in Google search results. This can include multiple impressions if the same user performs multiple searches that show your page.

Inbound Link: An inbound link is like a vote for your website. The more votes (a.k.a. links), the higher it ranks for its topic or keyword phrase in search results. When another page links to a page with high authority or trust, it’s considered a better link than one from a less authoritative site, so you want to target those types of sites when getting links built back to your own site!

Index Coverage report: This is where we can see how Google views our site’s pages and if any issues need to be addressed before submitting them for indexing again or requesting

Index: A search engine’s database contains the keywords and key phrases for every document in its collection. The index also includes a list of the documents where each keyword or key phrase occurs.

Indexability: When you create a new web page, you can tell Google to ignore it by using the “no-index” meta tag. Alternatively, if you want Google to include your page in its index, you can either use the “index” meta tag or not use any tag since not using any meta tags is equivalent to using the “index” tag. If Googlebot comes across a web page and it’s not indexed, it won’t appear in Google’s index. The following example shows a “no-index” meta tag:

Indexed Page: An indexed page is one that’s been added to Google’s index. When a page is indexed, it can appear in organic search results for queries related to its content.

Indexing: The process by which search engines crawl websites for information and add that information to their database

Information Architecture:  the way that information is presented on a website, including where it’s placed, how it’s organized, and the way that users can navigate through the site. It can be visualized as a flowchart of the site. Information architecture aims to create a structure that makes it easy for users to find what they’re looking for without getting frustrated or confused.

Informational Queries: Queries made by users seeking knowledge about a topic, often to inform themselves on a purchase they want to make. They’re usually longer and more specific than navigational queries.

Intent: The intent of a search query is what the user hopes to accomplish by doing that particular search. Intent can be broken down into four categories: navigational (finding a specific site), commercial (finding information about products or services), transactional (purchasing something), and informational (gathering more information about something).

Internal Link: A link on a website that points to another page on the same site. Internal links can improve user experience and increase search engine optimization (SEO) to help users navigate your site more efficiently. Google’s crawler can find all of the pages on your site.

IP Address: Every internet-connected device has a unique identifier called an IP address. It’s a string of numbers that represent your location and allow websites and other online services to know where you are connecting from. Your IP address is not the same as your physical address or location, although it can often be used to estimate those things based on what service provider you are using.


SEO Glossary Letter J

JavaScript (JS): A programming language used to make web pages interactive. It runs on the client-side (i.e., the user’s browser) rather than the server (i.e., the website). JS is often used to validate forms before submitting, animate page elements, and many other customer-facing applications.

JSON-LD: JavaScript Object Notation for Linked Data. A lightweight data-interchange format based on JavaScript syntax with semantics based on linked data principles. JSON-LD is designed to be “readable” both by humans and machines and can be used to serialize RDF (Resource Description Framework).


Glossary Letter K

Kanban: A Japanese term for “visual card.” Concerning web optimization, it refers to a system that sites use to manage their workflows, where cards are used to represent tasks and prioritize them. Toyota developed Kanban to control and optimize its manufacturing. In the context of web optimization, this would mean using Kanban to manage the workflows of designers, developers, copywriters, and others who contribute to optimizing your site.

Key Performance Indicator (KPI): is a metric that you use to measure how well your company or site achieves its goals. You can use KPIs to count how many products you’ve sold, how many people are on your site at any given time, or how much time people are spending on your site.

Keyword Cannibalization: when multiple pages on a website are optimized for the same keyword, there are fewer clicks for that keyword and weaker SEO results overall.

Keyword Density: How often a keyword appears in a text. Today, Google uses LSI (Latent Semantic Indexing) instead of keyword density to determine what a text is about and its relevance for specific queries.

Keyword Difficulty: How hard it is to rank for a given keyword relative to other keywords. The difficulty is calculated algorithmically and depends on how many sites are trying to rank for that term and how relevant those sites are to it.

Keyword Explorer: A tool used in keyword research that helps you discover new keywords and organize them into groups based on common themes. The tool also provides historical data about search volume and competition, among other things.

Keyword Research: The process of finding popular terms people are searching for, usually so you can optimize your site for them. This helps you understand what your target audience is already looking for so you can create content that meets their needs, and it’s also helpful in coming up with blog post ideas and other types of content marketing.

Keyword Stuffing: This is an old SEO trick that once worked but no longer did. It involves inserting a keyword repeatedly on a page to rank for that keyword. In the past, this was effective because search algorithms were not sophisticated enough to discount such pages. However, search engines can now detect which pages are full of keyword stuffing and will not rank them well.

Keyword: A keyword is any word or phrase with significant search volume on Google. It can be used in SEO to help target specific audiences for your business. For example, if you own a windmill business in Amsterdam called “Windmillz,” you might decide that “windmills” and “Amsterdam” are important keywords for your website because many people search for them online (and, therefore, may also be interested in your business). 

Knowledge Graph: Google’s knowledge baseGoogle’s knowledge base enhances its search engine’s results with information gathered from various sources. This information is presented to users in an infobox next to the search results. When relevant, data from the Knowledge Graph is automatically added into the mix of search results by Google algorithms, not by human editors.

Knowledge Panel: A box that appears on a Google search results page when a user searches a specific topic. It contains information on the subject, such as an overview, key facts, and related issues, and is meant to help users answer their questions quickly.


SEO Glossary Letter L

Landing Page: On a website, a Landing Page is any page that users arrive on after clicking on a link or advertisement. Typically, this isn’t the home but another page—such as a product page or blog post—with content relevant to what they were looking for. When optimizing landing pages, it’s crucial to think about what they are looking for and ensure that your content matches their expectations!

Latent Semantic Indexing (LSI): LSI is a way for search engines to understand the relationship between words by using statistics to analyze how often certain words appear near each other. For example, when analyzing the word “horse,” LSI can identify related terms like “hoof” and “tail.” This allows search engines to understand better what content is about.

Lazy loading: A technique used for web optimization that allows content on a page to load only as it’s needed. For instance, if you have ten images on your website, but only one is visible when the page loads, lazy loading allows only one image to be loaded initially. As the user scrolls down and more pictures become visible, they will load in. 

Lead: A person interested in a company or product and therefore may one day become a customer. Leads are qualified based on their ability, willingness to spend money, and interest strength in your company or product.

Link accessibility: describes how easily search engines can crawl through links on a page. A navigation bar at the top provides links to all pages on your site that would be very accessible to search engines; if all of the links are buried in JavaScript code, they may not be accessible to search engines. 

Link Bait: Content written or created specifically to attract links from other websites. Usually, link bait is content that offers value in entertainment or information—such as a listicle or an infographic—that promotes sharing by external sites.

Link Building: An SEO strategy focused on acquiring backlinks and specific links from other websites that point to your site. This technique is a significant component of off-page SEO and is often regarded as the most challenging part of the process.

Link Equity: Also known as “link juice”, it is one of the critical components of Google’s algorithm. Equity is distributed across all links on a website and impacts search rankings.

Link Exchange: When two sites agree to include links to each other’s sites.

Link Explorer: A tool created by Moz that allows users to find backlinks for any website and analyze them for various SEO-related metrics such as Domain Authority, Page Authority, IP location and domain country data, anchor text distribution, and linking domain statistics. It also provides information about MozRank and MozTrust.

Link Farm: Is a group of websites that all have the sole purpose of linking to other websites to help improve their search engine rankings. Farms are considered spammy and should be avoided at all costs.

Link Juice: A link’s ability to provide value to a site. Most commonly, this is a measure of the link’s authority. 

Link Profile: The distribution of links based on the ranking factors. For example, if an anchor text link has a high trust rank and a low authority rank, it is considered to have a higher link profile rank than a link with a low trust rank and a high authority rank.

Link Velocity: The rate at which new links are added to your site. This is important because the more links you have, the more link juice you have, resulting in better SEO rankings. However, adding too many links at once could look suspicious, so it is important to add links gradually.

Link volume: The total number of links connected to a website or piece of content. The higher the link volume, the stronger the website’s ability to rank highly and pass link juice on to other websites

Link: refers to a hyperlink. (See hyperlink)

Local business schema: Local business schema is a type of structured data markup that can be used by local businesses to provide information about themselves on their websites. Search engines automatically detect the schema and inform them of essential details about your business and local listings.

Local pack: This is a collection of three businesses that appear in a box at the top of Google’s local search results. The companies are sorted by distance from the searcher’s location. Companies can choose to optimize for the local pack by improving their local SEO.

Local queries: A local query is any query that contains at least one location indicator (e.g., city or zip code) or is made from a device with location services turned on. If I typed “pizza near me” into Google on my desktop computer, I would still be making a local query because my pc has location services turned on.

Log File Analysis: This is the process of going through log files—a record of all the traffic your site receives—and pulling insights from them so you can make improvements to your website.

Log File: A file that records user activity on a Web site. It stores information about each visit to the site, including the visitor’s geographical region, IP address, browser type, device type, operating system type and version number, and what pages of the Web site the visitor saw.

Login Forms: These are where your users enter their usernames and passwords to access their accounts on your site. A login form should never be located in plain sight or unsecured so that only authorized users (the ones who know the password) get access to it.

Long-Tail Keyword: A keyword phrase that is more specific and targeted than standard, single-word terms used for search queries. Long-tails are often used for SEO purposes and are less competitive than traditional ones because they are more focused and targeted; however, they typically have lower search volumes than single-word ones.

Machine Learning: An advanced form of artificial intelligence (AI) allows computer programs to learn from the data exposed. The more data a program is exposed to, the better it retains and the more it can do. Machine learning has many practical applications in SEO and other marketing fields.

Manual Action: A manual action refers to an action taken on a website by a human reviewer at Google rather than as a response to algorithmic signals. For example, if Google finds evidence of spammy links on a site, it will respond with a manual action rather than an algorithmic demotion.

Manual penalty: A manually issued penalty is similar to an algorithmic penalty in that it results in lowered rankings in SERPs; however, unlike algorithmic penalties (which are issued automatically), manual penalties are issued by human reviewers at Google and tend to be triggered when they find violations of Google’s Webmaster Guidelines.

Meta Description: This is a snippet of text that describes what your page is about. It appears under your page title on search results pages. While they’re not used in rankings directly, they affect how many people click on your page and how many visitors your website has, so it’s essential to write an accurate and descriptive meta description.

Meta Keywords: A tag that provides information about a web page for search engine optimization–specifically, it includes keywords that describe the page’s content.

Meta robots tag: A tag that specifies how search engines should index and crawl your website. It’s placed in the <head> of your website (usually within the <meta name> tag) and can be used to tell search engines not to index or crawl certain pages on your site.

Meta Tags: are code used in a webpage’s header section to provide information about the page. Meta tags do not appear on a webpage itself—they only appear when you look at the “source code” of a website.

Metric: data points used to measure performance against goals. Conversions are one example of a metric; however, many others include bounce rate, time on site, pages per session, and more.

Minification: the practice of removing or replacing unnecessary text or markup from a web page to reduce total file size and increase load speed. Minification can be applied to CSS, HTML, and JavaScript files.

Mobile Device: computing device that users can use on the go. Mobile devices include smartphones, tablets, smartwatches, and other portable computing devices. A mobile device can also refer to a desktop computer connected to the internet via a cellular connection instead of a Wi-Fi network.

MozBar: A free download offered by SEO software company Moz for Chrome and Firefox browsers. Mozbar enables users to compare the metrics of different websites side by side without leaving their web browser.

Natural Listings or Organic Listings ­ Results: Results are listed at the top of SERP based on the search engine’s algorithm; they appear naturally based on their relevance to the query.

Navigation: Navigating your way around a site or navigating from one site to another. Navigation also gets from one page to another within site or from one place to another in an application.

Navigational queries: Queries visitors use to navigate a website, such as brand-related searches, domain name searches, and site-specific product searches. These types of queries often result in “no-click” traffic since users know precisely where they want to go after searching (for example: searching for “Facebook” instead of typing http://facebook.com directly into their browser).

Negative SEO: A tactic used by some unscrupulous SEOs to negatively impact another website’s rankings in the search engines. Negative SEO tactics include creating bad links pointing at your competition’s websites from bad neighborhoods on the web.

Niche: is a sub-section of a market. In the context of SEO, it refers to the area where you and your competitors fall on the spectrum between broad and highly competitive keywords and terms and precise, long-tail keywords that are more likely to convert because they are more likely to be typed in by people who have an intent to buy.

Noarchive Tag: An HTML tag indicating that a web page should not be cached. Noarchive is used to prevent users from seeing outdated information on a webpage, but it also means that the search engines will keep crawling the site more frequently and use more of their resources to do so.

NoFollow Tag: Rel= “nofollow” is an HTML that tells search engines not to follow certain links on a page. These links may be paid links, so this attribute conveys to the search engine that it is not an editorial link (a link placed consciously by a site owner) but rather an advertisement and should not be counted as part of the site’s content and ranking.

NoIndex tag: A NoIndex tag is a meta tag that prevents search engines from indexing a page. Some use it to keep their work in progress out of the search engine results while still working on the page, and others use it to prevent duplicate content issues or avoid having information indexed that is no longer relevant.

Nosnippet Tag: tells search engines not to generate a search snippet for a given page or set of pages. This can be useful in cases where the snippet would be inaccurate, incomplete, or otherwise undesirable for a particular page.

Not provided: is a value that shows up in place of actual keywords when those keywords are not passed on to Google Analytics. It can occur in two ways: 1) when a user is signed into Google while visiting your site and 2) when data is encrypted (HTTPS). “Not provided” keywords are unavailable in your Google Analytics keyword reports and cannot be used as part of your SEO strategy.

Organic Traffic: Refers to visitors who arrive at your website or app through unpaid search engine results instead of paid advertisements. This term is also used to refer to foods grown without pesticides or other chemicals.

Orphan Page: A page on your website that is not linked from any other page; users cannot find these pages unless linked from another site or if users type in the exact URL.

Outbound Link: Any link on your website that leads to an external site. For example, if you have a link in your blog post for “Learn more about [company]” that takes the reader to another page on your site, that’s an outbound link.

Page Authority: a metric based on data from Moz, and it is an estimate of how well a given web page will perform in search engine results. This metric is calculated using the Mozscape web index data and includes linking root domains, number of total links, MozRank, MozTrust, etc.

Page Speed: This refers to the time it takes for websites or web pages to load when a user visits them ultimately. According to Google’s PageSpeed Insights guidelines, website performance should be measured by “time to the first byte,” meaning the time it takes for the first byte of data from the server to reach the user’s browser. Page speed is not directly associated with search rankings, but it impacts user experience, affecting SEO.

PageRank: A measure of how important a website is based on how many other websites link. This was created by Google and has since been replaced by other methods of determining ranking importance, but it’s still often used as a shorthand.

Pages per session: how many pages a user visits on your website before exiting. If you want to determine the success of a specific page, pay attention to this metric. Pages per session will show you how long users stay when they reach that page and what other pages they visit afterward.

Paid Search: A form of online advertising where advertisers bid on keywords to display their ads as paid results on a SERP. Ads are triggered when a user searches for a specific keyword or phrase. Paid search, also called pay per click (PPC), allows the advertiser to control which pages the searcher will be directed towards after clicking. Paid is typically more targeted than organic search because advertisers can choose which keywords they want their ads to show up for. Yahoo and Yandex are examples of paid search platforms.

Pay­ Per ­Click (PPC): A type of paid search, pay­per­click is an advertising model where users are charged for the number of clicks they receive from the search engine results. It’s a model that allows advertisers to pay for their ad only when it gets clicked on and does not charge for their ad being displayed in the results.

People Also Ask boxes: Also known as PAA or related questions boxes, they are a part of Google’s SERPs that display relevant questions users have searched for similar to the one they just searched. They appear after the first query result and can be expanded by clicking “more questions” at the bottom.

Performance-Based Navigation (PBN): is a way to improve your website’s rank in organic search results by improving its domain authority. This is done by purchasing expired domains with pre-existing high levels of domain authority and linking them to your website.

Persona: A fictional representation of a group of users who use the site at different times. The persona represents the needs and desires of a specific type of user, which helps web developers design experiences that cater to those needs.

Personalization: s the practice of using data to adapt a website or platform to serve individual users better. For example, a website might personalize content by offering an article in French if a user visits from France. Or it might personalize content by providing a piece about tennis if a user’s past behavior indicates that he is interested in tennis. Personalization can be based on many things, including location, historical behavior on your site or platform, and other factors (e.g., time of day).

PHP: A server-side scripting language commonly used in dynamic sites. Code processes on the server rather than in the browser, allowing for more secure and robust websites. PHP is implemented in HTML by using unique tags that indicate where PHP code should be processed.

Pogo-sticking: When a user clicks on a result in a search query and returns to the results page without visiting any other pages. Mismatching search queries can cause a high pogo-sticking rate with the content on a landing page or a poor user experience on the landing page.

Portable Document Format (PDF): A file format used for documents that are not intended to be edited but instead viewed and printed. While PDFs are not ideal for use as web pages, some websites use PDFs for their online marketing collateral (for example, white papers and case studies).

Position: how high your web page appears on the search engine results page for a specific search query. The place is calculated using various signals, including quality of content, page’s relevancy to the search query, functionality of the site, and the domain authority.

Programming language: A set of rules tells your computer what to do with data put into files or other types of storage on your computer’s hard drive. Programming languages are commonly used to make websites work appropriately by telling browsers how to display them.

Prominence: is a way to measure how visible something is. For example, if you were to Google “best ice cream,” the first thing that pops up at the top of your search results is the most prominent result.

Protocol: A protocol is one of the ways that computers communicate with each other. Protocols determine what kind of communication can be used and how information can be transmitted and received.

Pruning: s when you remove parts of something that are no longer useful. For example, if you have many pictures on your computer that you don’t need anymore, you can delete them to make more space on your computer—this would be pruning.

Purchased links: are links that exist on one website but lead to another website. For example, if you were reading an article about cleaning products and there was a link in the middle of the article that said, “Click here to find out more about [company name] cleaning products,” this would be an example of a purchased link.

Qualified Lead: A person or business has indicated that they’re interested in buying your product. There are many ways to qualify leads, but generally, you have to have contact information (email address, phone number, etc.) and a statement that you believe they intend to purchase your product soon.

Qualified Traffic: This is the audience you’ve identified as interested in your products. You can locate qualified traffic by seeing how people interact with your company’s content, email campaigns, or other marketing and outreach methods.

Quality Content:  is content that’s not only well-written but also relevant and useful to the reader. Quality content gets straight to the point and provides value beyond entertaining or informative. To get quality content, you need to focus on writing content that your audience would be interested in reading instead of writing whatever you think would do best in search engines or other algorithms.

Quality Link: link from one website to another determined to be authoritative and trustworthy, usually by a third party. Links from high-quality websites will benefit your website more than links from lower-quality websites.

Query or Search Term: A query is a word or group of words used to search for information. Queries can be primary keywords, long-tail keywords, or even questions. A query is not synonymous with a search engine but refers to the words or terms a user enters when searching.

Quicken Data Format (QDF): the file extension format used by Quicken, Intuit’s financial software. The QDF file format is used to store financial records, such as budgets and transactions, organized. Quicken can open PDF files, but they are not compatible with other programs.

Schema.org: a set of public schemas (or structured data) that web admins can implement to help their websites get better search visibility in Google Search results. Schema.org originated as an initiative between Google, Bing, Yahoo!, and Yandex to make it easier for site owners to provide more detailed information about their sites to enable rich snippets in search engines.

Scraped content: An exact copy of all or part of another Web site. Scraped content is generally considered bad for search engine optimization, as it doesn’t add value for a user—it just creates more results with the same information as other results.

Scroll depth: A measure of how far down the page the user has scrolled during their visit. This can be used to improve page design and to identify where users are abandoning their visits.

Scrum board: A visual way of tracking progress on a project in an agile environment. It typically includes cards with tasks, which can be moved from one stage of development to another as the process moves forward.

Search Engine Marketing (SEM): Advertising on the search engine results page (SERP). SEM campaigns focus on improving visibility on the SERP through advertising to drive users to your website.

This is achieved by enhancing a website’s technical architecture and content, ensuring it is relevant to the terms people search for. The goal of SEO is to improve rankings for relevant keywords.

Search Engine Results Page (SERP): The page a search engine displays when an end-user enters a query. The results are made up of paid listings and organic listings. Paid listings are shown on the SERP because the advertiser purchased them; organic listings are those that appear naturally because they match the user’s query.

Search Engine: A software system that indexes information on websites so that users can perform keyword searches and find relevant websites. Search engines such as Google and Bing use spiders, or web crawlers, that visit websites on the internet, retrieve their content, and index it in a database. When a person enters a query into a search engine, the search engine uses algorithms to determine which sites to show.

Search Forms: are boxes on Web pages that let users enter keywords for searches. Site visitors can then click “search” to a SERP with all results matching their keywords.

Search History: A record of searches a person has made in the past. Information about a user’s search history delivers personalized results, such as new information about topics the user has searched for recently or predictions of what the user is searching for based on past behavior.

Search Quality Rater Guidelines: Used by Google to train its search evaluators and used as a general guide for best SEO practices. The guidelines provide users with a positive experience from their search engine results page (SERP) visit.

Search traffic: This phrase is used to refer to the amount of traffic that goes to a site through organic searches. There are other types of traffic in SEO, but this one relates explicitly to organic searches. The ranking of a page changes its traffic level.

Search volume: The number of times a phrase or word is searched over time in search engines. This can be measured over varying periods, from daily or monthly trends to long-term research for general trends. It’s essential to figure out which search volumes are most significant for your content planning process.

Seasonal trends: These keywords have strong usage spikes or dips over the year. Maybe your products are only popular during certain seasons, or perhaps you want to maximize returns by ramping up advertising for certain products during peak seasons. Either way, you want to make sure your campaigns capitalize on seasonal trends in your industry when they arise.

Seed Keywords: These are the starting points you use to build a keyword list to help you achieve your optimal SEO goals. Typically, these words are relevant to your business and describe a product or service you offer. You can find seed keywords by running a query through Google Autosuggest and using their suggested search terms as your starting point for further research. 

Sentiment: Sentiment is the feeling or emotion associated with a piece of content. Advertisers generally want positive sentiment around their products and services to drive sales, but it’s also vital for them to identify negative sentiment to address any issues with their offerings before it hurts their brand reputation too much.

SERP Features: Aree elements on search engine results pages (SERPs) provide users with additional information about their query without leaving the results page. Common examples of SERP features include knowledge panels and local packs.

Session or Visit: A visit is a single engagement (of any length) with a site by a user. A session is a total of time spent on a website during a visit.

Share of Voice: The percent of impressions won in search results for a specific keyword, brand name, etc., compared to others in the industry. This metric can also be used as a competitor metric to determine who wins in the search. Not to be confused with Share of Market.

Sitelinks: Search results are displayed below a Web page’s title, link, and meta description. Typically only displayed if Google determines these links are relevant to the user’s search query.

Sitemap: A complete list of all pages available on a website. Sitemaps are helpful for SEO as they make it easier for Google to crawl through your site and index all available pages.

Sitewide Links: A sitewide link is a link that appears on every page of a website. These links are often found in the site’s header or footer, and they are usually used to direct visitors to the highest-priority pages on a site, such as the home page or “About” page.

Social Media Platforms (websites and apps): These websites and apps allow users to create and share content and interact with other users. Common examples of social media platforms include Facebook, Twitter, YouTube, Pinterest, Instagram, LinkedIn, Snapchat, Telegram, WhatsApp, Tumblr, Reddit, Flickr, TikTok, and Viber.

Social Media: The many platforms that enable people to communicate via the internet. Social media is a crucial part of modern life for many people worldwide; it also plays a vital role in business marketing efforts. These platforms are constantly changing as new social media sites emerge and trends shift toward different types of content or functions.

Social Network: A social network is a group of people who interact through various channels. Social networks exist in person as well as online. Online social networks include platforms like Facebook and Twitter that allow people to connect over the internet.

Social Signal: Online activity that shows a person’s interest or preference for something. Search engines frequently use social signals to determine the popularity of content and sites, which are then used to rank them in search results.

Spam Score: A percentage that describes how closely a given site resembles known spam sites. The score is calculated by running a series of algorithms on the site’s pages and can be generated by free online tools.

Spam: Unsolicited or unwanted information (usually email) sent in bulk to several recipients. The term “spam” was derived from a skit on Monty Python’s Flying Circus. In this skit, customers at a restaurant repeatedly order a meal called spam, which appears throughout the scene without explanation. The name “spam” caught on as a term for unwanted email because it is frequently repeated without context.

Spammy tactics: Unethical SEO practices designed to manipulate or trick search engines into boosting keyword rankings or site visibility. This includes using automated programs (“bots”) to simulate traffic, using misleading page titles or meta tags to trick readers into clicking through, and running link farms (networks of sites that are all linked together).

Spider: A spider is a program that automatically browses the internet to index its pages for search engines. The process of a spider locating and indexing pages is called crawling.

Split Testing: Split testing (aka A/B testing) compares different versions of a web page or other marketing material to see which version performs better. This is done by randomly showing different visitors different versions of the content and then measuring metrics such as click-through rates, bounce rates, or time on page to determine which version performs better in terms of the goals of the content.

SRCSET: is the URL where your images, GIFs, and videos will be stored on your site. The default setting is usually /images for pictures and /gifs for GIFs. We recommend constantly changing this so it’s not something like /images/hi-res.gif (which could go anywhere in the world) or, worse, like /gifs/hi-res.gif (they’re very hard to find).

SSL certificate: used to encrypt data on a website before it’s sent from the server to the browser. SSL certificates are also required for secure connections when connecting to an online store like Amazon or eBay.

Status Codes: A status code can be a number or a message displayed in response to an error or other issue. The first digit of the status code indicates the class of response and is used as the general indicator of whether a request was successful. For example, a 2xx code means the request was successfully received and processed; a 4xx code means there was an error in the client’s request; and a 5xx code means there was an error on the server’s side of things likely because of something the client did.

Stop Word: A stop word is a word that search engines ignore when crawling content. Stop words are often prepositions, conjunctions, pronouns, and articles. For example, “and,” “the,” “or,” and “but” are all stop words in English. Stop words are ignored because they provide no semantic value for understanding the meaning of a phrase or sentence.

Structured Data: Refers to any data in a fixed field within a record or file. This includes relational databases and spreadsheet files. A data model usually defines the data that is found in these fields. This model may be associated with a database or one or more files.

Subdomain: A subset of another domain. It is usually used for organizational purposes (e.g., http://blog.website.com ). This can be helpful for sites with large amounts of content because it allows you to segment content into different sections or subsections of your site (e.g., careers section or product pages).

Taxonomy:  A taxonomy is a way of categorizing content. A taxonomy is usually hierarchical so that each category contains subcategories, and each subcategory contains more granular types. In the context of Web Optimization, a taxonomy helps visitors find the content they’re looking for by allowing them to break down their search into smaller categories.

Thin content: Content that provides little value, either because it has no accurate information or is so short that there’s not much for readers to consume. Thin content can signal that you’re trying to stuff keywords into your text; search engines are increasingly wary of this practice and likely push down pages with narrow content.

Thumbnails: A miniature version or preview of a larger image. Thumbnails are typically used to display a preview of an image before clicking on it to view it at full size. They are also used as links to open something in another window, such as clicking on a thumbnail for an item for sale to see details about that item on a new page.

Time on page: Time on-page is the amount of time a user spends viewing a particular web page before navigating away. This metric can help you determine the quality of your content and whether visitors are finding it engaging enough to read through it entirely.

Title tag: The title tag helps search engines understand your page better. It’s also the first thing people see when they search for something relevant to your page, so take some time to think about what will get people to click on it. They’re usually 50-60 characters long and include the keywords you want your page to rank for.

Top-Level Domain (TLD): A TLD is the domain extension at the end of a URL (like .com). There are lots of different ones, and they have different meanings. For example, a .edu means that the site belongs to an educational institution, while a .gov means a government site.

Traffic Acquisition: How visitors arrive at your website. Some examples include direct traffic (someone types your URL into their browser), referral traffic (someone clicks a link to your site from another site), social traffic (people visit your site after clicking a link on social media), and paid traffic (visitors come to your site through an ad).

Traffic: The volume of visitors to a website or webpage over a period of time. Traffic metrics can evaluate how successful a web page attracts visitors from search engines over time.

Transactional queries: this is a search term indicating that the user intends to complete an online purchase or other commercial transaction. A typical example of a transactional query would be “buy blue shoes.” It is commonly theorized that users who conduct transactional queries are further along in the buyer’s journey and, therefore, more likely to convert.

Trust: the way search engines decide whether your page is authoritative and worthy of ranking high for specific keywords. This is, of course, complicated, but it’s based on things like backlinks, internal linking, domain age and authority, and more.

TrustRank: A method of determining which pages on the web should be trusted and therefore presented first in results pages. It categorizes trusted seed pages, then propagates that trust throughout the web graph. Pages with the highest TrustRank are considered the most trustworthy and are shown at the top of SERPs.

Uniform Resource Locator (URL): The unique address of a web page on the internet, which includes the protocol (for example, http://), server name (for example, www.), and path (for example, /glossary).

Unique visitor: The number of unique visitors to a website, calculated by looking at a selected period (e.g., one month) and counting the number of individual clients who visited the site.

Universal Search: A feature on search engine results pages displays results from different entities within the engine’s index (e.g., videos, news, images) and traditional organic search results.

Unnatural link: Link that appears to have been created to manipulate search engine rankings rather than creating value for a user. This is often done by spamming links on external sites or making a large number of links within the same website. Links are considered unnatural when they are not part of a regular linking pattern expected in typical circumstances.

URL folders: Directories where you can find content on a website. For example, if you want to view all of the content on the topic “glossaries,” you would go to the URL folder “/glossaries”. This will give you an organized list of glossaries that can be sorted by date, author, or keyword.

URL Parameter: The URL parameter is a set of characters following the question mark in a URL that communicates information that the server will need to provide the correct content to a web server. It is often used in dynamic websites built with a Content Management System (CMS) such as WordPress, Drupal, or Joomla. The parameter helps the server determine what kind of content to display for a given page. For example, if you visit a news site and click on an article about dogs, the URL parameter would let the website’s server know which piece you meant. A URL parameter can be as simple as “id=5” or more complex, depending on the amount of content and features available on your site.

Usability: The ease with which users can navigate through and accomplish tasks on your website. Many variables affect usability, including page load speed, sound and video quality, clarity of text, user-friendliness of buttons and other interactives, and so much more. Usability issues can create obstacles between your customers and their goals when using your site; good usability makes it possible for them to find what they need quickly and easily.

User-Agent: A string of text that identifies the web browser to the web server, enabling the webserver to send data about the web browser’s capabilities back to the browser.

User Experience (UX): The overall experience users have with a product or service, considering all aspects of their interactions with it (including accessibility) from start to finish and beyond—even after the product has been purchased or consumed.

User-Generated Content (UGC): Content created by online users rather than companies or brands. UGC can be found on websites, social media platforms, and other online channels. An example of UGC is a customer comment about a product on a retailer’s website.

UTM code: A line of text added to the end of a web page URL that identifies the traffic source to that page. For example, if you post a link to your website on Facebook, you could add a UTM code at the end of it to tell Google Analytics exactly where the traffic is coming from.

Vertical Search: Vertical search engines are specialized search engines that focus on specific topics or industries rather than providing general results across all possible websites. For example, Google Shopping and AllRecipes are vertical searches for shopping results and recipes. Vertical search engines can sometimes give better results.

Virtual Assistant: Virtual assistants are programs that automate specific tasks for you. You can ask them questions or give them commands like “show me my schedule for tomorrow” or “create a new appointment at 2 pm with Delilah.”

Visibility: refers to the number of people who visit a website. Monthly visitors generally measure visibility, and it can be improved by increasing the number of links to a website, optimizing web pages for search engines, and using social media platforms to increase brand awareness.

Voice Search: Voice Search is a relatively new feature that allows users to speak their search query instead of typing it into a search bar. Voice Search will enable users to search more quickly and perform searches while engaged in other tasks.

Webmaster guidelines: Webmaster guidelines are effective rules for how to design a website so that it appears on search engine results pages (SERPs). These rules include making sure that titles are clear and page content matches its title or that web pages have working backlinks and meta tags. Following webmaster guidelines increases the likelihood of a site’s web pages appearing on SERPs.

Webpage: A webpage is a single page within a more extensive website. It can be reached directly through its unique URL (or Internet address). Webpages are often grouped cohesively based on common themes or general topics, which help visitors navigate between pages and find what they’re looking for more easily.

Website Navigation: The user interface allows users to interact with a website. It is the primary means of navigation through a website and gives users access to all the site’s information. Web navigation can be done in various ways, such as using clickable buttons, drop-down menus, or links. It also includes the text and images to indicate what you’re clicking on.

Website: A website is a collection of web pages (or documents) that can be viewed online. It usually consists of text and images but may also include other media such as video or audio files and hyperlinks to other websites. You may have heard it being “on the internet,” which means it’s accessible through any device with an internet connection (such as your computer).

Webspam (or spamdexing): The deliberate manipulation of search engine results in pages to get higher rankings for particular websites, often by using black-hat techniques such as keyword stuffing, cloaking, and link farming.

White Hat: The term “white hat” refers to SEO techniques that align with the guidelines from search engines like Google, Bing, and Yahoo! White hat techniques include creating high-quality content and building relevant links.

Word Count: The number of words in a text document or website. This is particularly important in blog entries. The most successful word entries have at least 700 words.

WordPress: WordPress is a free and open-source content management system (CMS) based on PHP and MySQL that runs on servers and allows users to create, edit and manage their websites.

XML: is an acronym for eXtensible Markup Language. It’s an open standard for encoding data in XML format. It was created by an international group of companies, including IBM and Microsoft. Still, it gained wide popularity when adopted by the World Wide Web Consortium (W3C), which oversees web standards.

Yandex: Yandex is a Russian corporation that was founded in 1997. It provides Internet-related products and services such as an internet portal, an email service, an information retrieval system (Yandex Search), and many other web resources, including maps, videos, translations, etcetera.

YMYL pages: pages whose content can potentially affect a user’s future happiness, health, or wealth. These pages are considered to have high authority and must be vetted by Google engineers to ensure they meet a certain quality standard. They are often used in conjunction with the term E-A-T (Expertise, Authoritativeness, Trustworthiness), representing the qualities that makeup YMYL pages.

Yoast SEO: A WordPress plugin that helps optimize your website for search engines. Yoast SEO analyzes your web page’s content and improves it to make it more likely to be found by the type of users searching for that content.

YouTube: The second most popular search engine (the number of searches per month) after Google. Google owns YouTube but maintains its algorithm, updated multiple times since it was first launched in 2005. The most recent update was named “October 2021 Core Update” and focused on EAT and user experience signals. YouTube also announced plans to introduce a new ranking factor called “brand signals” later this year or early next year.
