SEO is one of the four score groups on every report. It covers everything that
affects search visibility: whether crawlers can reach and index your pages, how
your content and markup are structured, and how accessible the page is.

It's the broadest group, spanning 16 categories. Most rules run locally for
free; a few [cloud rules](/cloud/rules) use AI analysis or live search data and
are skipped when you're not logged in.

## Disable all SEO rules

SEO spans many rule prefixes, so disable per category rather than as one group:

```toml squirrel.toml
[rules]
disable = [
  "crawl/*", "core/*", "links/*", "content/*", "schema/*",
  "images/*", "social/*", "a11y/*", "mobile/*", "url/*",
  "i18n/*", "eeat/*", "local/*", "video/*", "analytics/*", "gaps/*",
]
```

See the [full rules reference](/rules) for the other score groups.
