Top 51 SEO Glossary in 2024

Do you ever feel like SEO jargon is beyond your understanding? Or have you felt lost trying to make sense of the terminology used in search engine optimization? Worry not; we all have been there. 

Understanding SEO terminology is easy; you just need the right guide to break down the concepts clearly and easily. Hence, this glossary provides clear definitions and explanations that help you navigate the world of SEO. 

So, let’s get started in alphabetical order. 


Algorithms refer to complex systems used by search engines like Google to determine the rankings and relevance of web pages. In simple words, algorithms are systems that consider hundreds of factors, such as user experience, quality, and content relevancy, to rank pages on SERPs.

When you publish content with images, links, and UI/UX design, search engines use algorithms to evaluate your content quality, user experience, and page authority. Based on this analysis, the algorithm ranks your page by rewarding quality content and penalizing low-quality material. 

Anchor Text

Anchor text is the visible, clickable text in a hyperlink that typically appears as bold, blue, underlined text that users can click on.

Moreover, Anchor text is part of an interim SEO strategy that helps improve contextual relevance and user navigation by guiding visitors to related content. This text is seen at the beginning of the content in the middle or in the author bio section. 

Backlinks are links from other websites that point to your website. They’re like votes of confidence, showing search engines that your site is valuable and trustworthy.

For example, if a popular blog links to one of your articles, that’s a backlink. This link tells search engines that your content is credible and relevant, which can improve your search rankings.

Bounce rate

Bounce rate is the percentage of visitors who leave your website after viewing just one page. A high bounce rate may suggest that users need help finding what they’re looking for on your site.

For example, if someone clicks on a link to your website, reads one page, and then leaves without interacting further, that counts as a bounce. To improve bounce rate, ensure your content is engaging and relevant to what visitors are searching for.

Call to Action

Call to Action (C.T.A.) prompts users to take a specific action, such as signing up for a newsletter or purchasing. C.T.A.s are often buttons or links with phrases like “Buy Now” or “Subscribe.”

For example, a C.T.A. might appear as a “Learn More” button at the end of a blog post. When readers click it, they may be directed to a page with more information or an offer. A strong C.T.A. can guide users through your website and improve conversions.


Citation is an online mention of a business’s name, address, and phone number (often called N.A.P.). Citations can appear on directories, websites, or social media platforms.

For example, if your business is listed on a local directory like Yelp or Google My Business with your name, address, and phone number, that’s a citation. Citations help improve your local search visibility and build trust with customers.


Content is anything you put on your website, including text, images, videos, and audio. It helps communicate information and engage your audience.

For example, a blog post with valuable tips for your readers is a type of content. It can also include images, infographics, and videos to make the post more engaging and informative. High-quality content keeps visitors interested and can improve your site’s search engine ranking.

Domain Authority

Domain Authority (DA) is a score that predicts how well a website will rank on search engines. It ranges from 1 to 100, with higher scores indicating better chances of ranking well in search results.

In the SEO industry, a website with a high Domain Authority is considered more trustworthy and authoritative. The score is calculated based on several factors, such as the quality and quantity of backlinks pointing to the site, its content quality, and other SEO metrics. A higher DA can lead to better visibility and ranking in search engine results, driving more organic traffic to the site.


De-indexing is the process of removing a webpage from a search engine’s index. When a page is de-indexed, it will not appear in search results. If a page violates search engine guidelines (e.g., using spammy or manipulative tactics), it may be de-indexed as a penalty.

When a page is de-indexed, it loses its visibility in search engines, affecting organic traffic. Following search engine guidelines and maintaining quality content is essential to prevent unwanted de-indexing.


Do-follow is a link that passes “link juice” or authority from one website to another. When a link is set as do-follow, it signals to search engines to consider it as an endorsement of the linked content.

Having do-follow links pointing to your site can be a significant benefit. These links can boost your website’s credibility and improve its ranking potential in search engine results. 

They act as a vote of confidence from other sites, showing search engines that your content is valuable and trustworthy. Building relationships with reputable websites that give you do-follow links can be an intelligent strategy for improving your site’s visibility and authority.


Engagement in SEO refers to how much and how well users interact with your website and its content. It includes metrics such as users’ time on your site, the number of pages they view, and how often they interact with elements like links, buttons, or forms.

When you have high engagement, it indicates that visitors find your content valuable and relevant. This can positively impact your search engine rankings because it shows search engines that your website provides a good user experience.


E.A.A.T. stands for Expertise, Experience, Authoritativeness, and Trustworthiness. It’s a concept that search engines, especially Google, use to evaluate the quality of a website’s content.

In terms of SEO, focusing on E.A.A.T. means creating content that demonstrates the following:

  • Expertise: The knowledge and skill in the subject area of the content.
  • Experience: The amount of experience you have in the field.
  • Authoritativeness: Being recognized as a credible and reliable source.
  • Trustworthiness: Ensuring your website and content are reliable, honest, and transparent.

Content that shows high levels of E.E.A.T. can rank better in search results because search engines want to present users with information they can trust. 

Error 404

Error 404 is a standard web error message, meaning a requested page cannot be found on a website. When users try to visit a URL that doesn’t exist, they encounter this error.

There are a few reasons why an Error 404 might be shown:

  • Broken Links: If a link on your site or another site that points to a page no longer exists, users will see an Error 404.
  • Mistyped URLs: If users mistyped a URL, they might encounter this error.
  • Removed Content: If a page has been deleted or moved without a redirect, users trying to access it will see an Error 404.

Addressing Error 404 issues on your site is essential to avoid frustrating visitors and losing potential traffic. 

A Featured Snippet is a summary of an answer to a search query that appears at the top of Google search results, above the regular listings. It’s also known as “position zero” because it ranks even higher than the first organic result.

Once a bot finds a page, it analyzes the content and adds it to the search engine’s index if it meets specific criteria.
