aeo.llms-txt-invalid

WarningAEO audit

/llms.txt exists but does not follow the llms.txt format, which requires an H1 title first.

What to change

Start the file with `# Site name`, then an optional `> one-line summary`, then H2 sections with links written as `- [Title](https://...): note`.

The documentation on llmstxt.org

A finding of this rule on a page carries the exact edits for that page: the markup it quotes, and what to write instead.

When it runs

Runs on every AEO audit: of a page, a crawl, a build directory or HTML. A warning is a problem that costs a page ranking, clicks or citations. Each finding takes 5 points off the page's score.

The severity here is the rule's usual one: a finding can be raised or lowered when the page gives a reason.

Run it, or skip it

Check a page for this rule alone, after a fix for instance:

npx @rivi-software/agentic-seo-check aeo https://example.com --rule aeo.llms-txt-invalid

Or from an assistant, with the MCP tool seo_aeo_audit:

{
  "url": "https://example.com",
  "rules": [
    "aeo.llms-txt-invalid"
  ]
}

To leave it out of an audit, pass --disable aeo.llms-txt-invalid on the command, or disableRules: ["aeo.llms-txt-invalid"] to a tool.
