  AI bot rules in robots.txt

  No explicit rules for GPTBot / ClaudeBot / Google-Extended

  How to fix

  Add `User-agent: GPTBot`, `User-agent: ClaudeBot`, `User-agent: Google-Extended` blocks with explicit Allow/Disallow so AI crawlers know your stance.

• !
  Content Signals declared

  No Cloudflare Content-Signal directive

  How to fix

  Add `Content-Signal: search=yes, ai-train=no, ai-input=yes` (tune the values to your policy) inside a User-agent group in robots.txt.

  Markdown content negotiation

  Returned text/html; charset=utf-8 despite Accept: text/markdown

  How to fix

  When `Accept: text/markdown` is sent, return the same content as Markdown (Content-Type: text/markdown). Agents prefer it because it's cheaper to parse than HTML.

• !
  Link header on /

  No Link header — agents can't follow alt-format relations

  How to fix

  Add an HTTP `Link:` header pointing agents at alternate representations, e.g. `Link: </openapi.json>; rel="service-desc"; type="application/openapi+json"`.

HTML signals that Google AI Search + LLM crawlers use to rank you.
