aeo.robots-txt-unreachable

WarningAEO audit

robots.txt answers a server error or does not answer, and crawlers treat that as "crawl nothing" (RFC 9309).

What to change

Make /robots.txt answer 200, or 404 when there is none. A 5xx or a timeout stops well-behaved crawlers, AI crawlers included.

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.robots-txt-unreachable

Or from an assistant, with the MCP tool seo_aeo_audit:

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

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