SEO Terms Glossary: 22 Words Every Owner Should Know

SEO terms glossary for business owners

SEO terms glossary is exactly what this is, a genuinely useful reference in one place. I give a brief version of this in my complete guide to SEO for Pakistani businesses, but a proper glossary is genuinely useful to have in one place, since SEO conversations get confusing fast once the acronyms start piling up. Here are the terms that come up constantly, explained plainly, with no assumption you already know the last five before you get to this one.

SEO Terms Glossary: The Basics

SEO, search engine optimization. Making your website easy for Google to find, understand, and trust enough to show to searchers.
SERP, search engine results page. The page of results Google shows after a search.
Organic traffic, visitors who arrive through unpaid search results, as opposed to clicking an ad.
Keyword, the word or phrase someone actually types or says when searching for something.
Ranking, where your page appears in the results for a specific search, position one being the top.

On-Page Terms

Title tag, the clickable headline shown in search results for your page.
Meta description, the short summary text shown under your title in search results.
H1, H2, H3, heading levels used to structure a page, from the main title down through sections and subsections.
Alt text, a plain description of an image, used for accessibility and to help search engines understand image content.
Internal link, a link from one page on your site to another page on the same site.

Off-Page and Authority Terms

Backlink, a link from another website pointing to yours, treated as a signal of credibility.
Domain authority, a rough, third-party estimate of how trusted a whole website is. Not an official Google metric, but a common industry shorthand.
Referring domain, a distinct website linking to you. More valuable as a spread than many links from the same single source.
Anchor text, the clickable text of a link.

Technical Terms

Crawl, Google’s automated process of discovering and reading pages across the web.
Index, Google’s stored database of pages it has crawled and considers worth potentially showing in results.
Schema markup, structured code added to a page describing exactly what it is to search engines and AI systems, covered in full in my technical SEO and AI Overviews guides.
Core Web Vitals, Google’s set of page-experience metrics measuring loading speed, interactivity, and visual stability.
Canonical tag, a technical signal telling Google which version of a page is the official one, used to avoid duplicate content issues.

E-E-A-T and AI Search Terms

E-E-A-T, experience, expertise, authoritativeness, and trustworthiness. Google’s framework for judging whether content deserves to be trusted.
AEO, answer engine optimization. Structuring content to become a direct answer, whether a featured snippet, a voice search result, or an AI Overview.
GEO, generative engine optimization. Earning a citation inside an answer generated by an AI system like ChatGPT or Google’s AI Overviews.
AI Overview, the AI-generated summary answer Google now shows at the top of many search results.
NLP, natural language processing. The technology letting a computer understand human language rather than just matching keywords.
Entity, a specific, recognizable thing, like your business, understood by search engines as a connected concept rather than just text on a page.
