The encyclopedia has over 90 technical terms from SEO and Generative Engine Optimization (GEO), explained plainly and clearly, from robots.txt and Core Web Vitals to AI Overviews, RAG and llms.txt.
What is the encyclopedia for?
SEO and GEO are full of jargon. If you stumble over a term in an analysis result, a wiki article or a conversation, look it up here. Each entry says briefly what is meant, and many terms also have a full article.
You'll find it under SEO Encyclopedia in the navigation. You don't need an account, it's public.
Finding terms
The overview page gives you two ways to a term:
- Search: type it into the search field, the list filters while you type.
- Index: an alphabetical directory of all terms. One click on a term jumps straight to its entry.
Entries and articles
The overview shows a short explanation for each term. Where there is an in-depth piece, the Full article link appears and opens the detail page.
There you find:
- the full article with subheadings
- a table of contents ("On this page") that you can jump from
- author (SEOFuxx editorial team), date of the last update and reading time
- code examples with a Copy button
- more encyclopedia articles to keep reading
Languages
The encyclopedia is available in German, English, Spanish and Dutch. You get terms and articles in the language you set for the site.
Encyclopedia and wiki: the difference
| Encyclopedia | Wiki | |
|---|---|---|
| Question | What does ... mean? | How do I ...? |
| Content | Terms explained | Step-by-step guides to SEOFuxx |
| Example | What is a canonical tag? | How to check canonicals in the Page Audit |
In practice it usually goes like this: you read in the wiki how a tool works and look up terms you don't know in the encyclopedia.
