## Which guides are available?

- **[SEO vs AEO vs GEO](/learn/aeo-vs-geo-vs-seo/)** defines each term in 50 words, compares them in one table, and explains what Google says versus what ChatGPT and Perplexity do.
- **[On-page checklist](/learn/checklist/)** lists every signal XEO Agent reads from server-delivered HTML, grouped by SEO, AEO, and GEO, with the pass rule and the finding code for each.

## What order should you read them in?

Read the comparison first if the three acronyms are new to you. It defines each term and shows how the same page serves all three. Then use the checklist as a working document while you fix a page, since each row maps to a finding the app will report. The method page is reference material for when you want to know why a score moved.

## How do these guides relate to the app?

The guides describe the rubric the app implements. When the rubric changes, the checklist and the [changelog](/changelog/) change with it. For the fetch model, scoring rules, and limitations, read [how scoring works](/method/). For how a local auditor differs from cloud scanners and AI visibility trackers, read the [comparison](/compare/cloud-aeo-tools/).

## Frequently asked questions

### Do these guides apply to any website?

Yes. The definitions and the checklist describe signals any public HTML page can carry. The finding codes are specific to XEO Agent, but the underlying checks such as canonical tags, question-led headings, FAQ schema, and author and date markers apply to any site.

### How often are the guides updated?

Whenever the scoring rubric changes or an engine publishes new guidance. Each page shows its last-updated date, and rubric changes are also recorded in the changelog.
