If you are new to the world of SEO, it can be daunting. There are so many acronyms, terms, and abbreviations that it’s difficult to know where to start. But don’t worry because this blog post will alleviate all your worries by providing an SEO glossary! It’s not as scary as you may think once you find out what each acronym means. We’ll go through them alphabetically for ease of use at the end of this article.
Above the Fold
Content that appears on a website before the user scrolls. Google created the Page Layout (Top Heavy) Algorithm in 2012 to lower the rankings of websites featuring too many ads in this space.
A complex computer program used by search engines to retrieve data and deliver results for a query. Search engines use a combination of algorithms to provide ranked web pages via a results page based on several ranking factors and signals.
Some algorithmic changes go entirely unnoticed. However, the impact of a significant algorithmic change can usually be seen relatively quickly, though the change sometimes takes a few weeks to roll out completely. Algorithmic changes come in three forms:
- Algorithm Update: The search engine changes certain signals of an existing algorithm.
- Algorithm Refresh: The search engine re-runs an existing algorithm using the exact same signals as last time.
- New Algorithm: The search engine adds a new algorithm to improve search quality. For example: Google Panda, Google Penguin.
HTML code provides information used by search engines and screen readers (for blind and visually-impaired people) to understand the contents of an image.
Also known as Alt Text
The science of collecting, analyzing, and interpreting data to take future action based on what has (or hasn’t) worked historically.
Also, see Google Analytics.
The clickable word or words of a link; this text is intended to provide contextual information to people and search engines about what the webpage or website being linked to is about.
Artificial Intelligence (AI)
The science of making computers perform tasks that require human intelligence; Rather than following a set of programmed rules (like an algorithm), an AI computer system is a digital brain that learns. AI can also make and carry out decisions without human intervention.
The combination of signals search engines used to assess websites and webpages for ranking.
Short for business-to-business. In B2B SEO, the buying cycle is more prolonged, products and services are more expensive, and the audience is professional decision-makers.
Short for business-to-consumer. In B2C SEO, the buying cycle is typically more straightforward (though it still varies by industry), products and services are (mostly) cheaper, and consumers are the audience.

Also see: Webspam
A publication of content, sorted in chronological order, with the most recent content appearing at the top. The content reflects personal or corporate interests and can be written by an individual or a group of contributors. Blogs were initially called web logs or weblogs.

There are two types of competition:
- Direct Competitors: Companies that sell similar products and/or services, serve the same needs, and target a similar audience both online and offline.
- SEO Competitors: Companies that vie for the same keywords and organic search visibility, but with unalike products or services that address different needs and/or target audiences.
- Words, images, videos, or sounds (or any combination thereof) that convey information that is meant to be distributed to and consumed by an audience.

Also known as Delisting
A list of websites, usually separated by related categories and maintained by human editors; Depending on the directory, inclusion could be free or paid. In the past, links from directories were highly sought after (e.g., DMOZ), leading to widespread abuse and devaluing this link building.

Larry Page and Sergey Brin founded the search engine in September 1998. Google marked a radical departure from human-edited web directories, relying on web crawling technology and a complex algorithm to analyze hyperlinking patterns to rank websites. Google is the most-used search engine in nearly every country in the world.
A free web analytics program can be used to track audience behavior, traffic acquisition sources, content performance, and much more.
Visit: Google Analytics
A practice intended to make a website rank number one for a surprising or controversial search phrase; this was accomplished by linking many websites to a particular webpage with specific anchor text to help it rank for that term.
For example, in 2003, President George W. Bush’s White House bio ranked number one searching for “miserable failure.”
The crawling web system Google uses to find and add new websites and webpages to its index.
A term was used starting in 2002 for the volatile period when Google updated its search index, roughly every month.
A Google search algorithm was officially announced in September 2013 after being in use for a month. The purpose of Hummingbird was to understand better the full context of queries (i.e., semantic search), rather than specific keywords, to provide better results.
Google Panda Algorithm
A major Google algorithm update that initially rolled out in February 2011was followed by numerous subsequent updates. The goal of Google Panda was to reduce the visibility of low-value content, often produced by “content farms. In 2016, Panda became part of Google’s core ranking algorithm.
Google Penguin Algorithm
A series of updates and refreshes followed a Google algorithm launched in April 2012. The goal of Penguin was to reduce the visibility of overly-optimized sites or sites that excessively abused specific spammy tactics (e.g., building low-quality links, keyword stuffing). In 2016, Penguin started running in real-time as a part of Google’s core algorithm.
Google Pigeon Update
The name (given by the SEO industry, not Google) of a significant Google local search update launched July 24, 2014; the goal of Pigeon was to improve the accuracy and relevance of local searches by leveraging more traditional Google ranking signals and improving distance and locating ranking parameters.
A significant Google algorithm change was officially introduced in October 2015, although it had been in testing for months before this. With RankBrain, Google added machine learning to its algorithm and called it the third most important ranking signal. In June 2016, it was revealed that RankBrain had been involved in every query and impacts rankings.
A theorized and debated (but never confirmed by Google) “waiting period” that prevents new websites from seeing the full benefit of their optimization efforts. Typically, this effect is witnessed most often with new sites targeting competitive keywords and can only be overcome when the site gains enough authority.
Google Search Console
Google’s Search Console offers several helpful features, including the ability to monitor sites for indexing errors and site speed. These pages are also used to communicate manual action notifications.
A website where you can explore data visualizations on the latest search trends, stories, and topics.

Keywords usually represent topics, ideas, or questions.
Also known as Keyphrase.
A type of self-competition that occurs when multiple pages from one website rank for the same query on a SERP. This can result in a lower CTR, diminished authority, and lower conversion rates than having one consolidated webpage that ranks well.
How often a word or phrase appears within the content of a webpage. At best, this unproven concept is outdated, if ever really mattered to search engines. There is no ideal percentage that will help a webpage rank better.
The process of discovering any relevant topics, subjects, and terms searchers enter into search engines, as well as the volume and competition level of those terms. This practice is made possible by a variety of free and paid tools.
Adding irrelevant keywords or repeating keywords beyond what is natural to a webpage in the hopes of increasing search rankings. This spam tactic is against Google’s Webmaster Guidelines and can result in a manual action.
Google uses an entity database to surface facts and information on people, places, and things (a.k.a., entities) and their connections in a Knowledge Panel or carousel at the top of search results on relevant queries.
A box appears at the top of, or on the right rail (desktop only), of Page 1 of Google’s search results for relevant queries. This panel contains facts and information on people, places, and things and related websites or Google searches.

A tag that can be added to the “head section of an HTML document. acts as a description of a webpage’s content. This content isn’t used in ranking algorithms but is often displayed as the “snippet that appears in the search results. Accurate and engaging descriptions can increase the organic click-through rate.
