Crawler access (robots.txt)

2/2 · pass

No robots.txt (HTTP 404): every crawler is allowed by default

  • GET /robots.txt -> HTTP 404
  • Unmentioned (allowed by default): GPTBot, ClaudeBot, OAI-SearchBot, PerplexityBot, Google-Extended, Amazonbot, CCBot, Bytespider

Fix: Optional: publish a robots.txt that names the AI crawlers you allow and points to your sitemap; without one your policy is implicit.
