Free tool · robots.txt

Check your robots.txt.

One wrong line in robots.txt can hide a whole site from Google. Enter your address and we'll fetch the file, apply the same matching rules Google uses, and flag anything that blocks important pages, scripts or styles.

What it checks

  • Whether Googlebot can reach your homepage and common sections
  • Rules that block CSS, JavaScript or images Google needs to render pages
  • A missing or relative Sitemap: line
  • Which AI crawlers (GPTBot, ClaudeBot, PerplexityBot, Google-Extended and more) are allowed
  • HTML served instead of text, oversize files and unreadable lines

Blocking AI crawlers is a choice, not an error. We show it so you can decide on purpose.
