aeo.content-signal-invalid

InfoAEO audit

A robots.txt Content-Signal line has a signal other than search, ai-input or ai-train, or a value other than yes or no.

What to change

Write Content-Signal as comma-separated pairs of search, ai-input or ai-train with yes or no, e.g. `Content-Signal: search=yes, ai-input=yes, ai-train=no`.

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. Info is a best practice: worth doing, rarely urgent, and --no-info leaves it out. Each finding takes 1 point 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.content-signal-invalid

Or from an assistant, with the MCP tool seo_aeo_audit:

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

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