Robots.txt checker

Fetch a public site's robots.txt file and inspect crawler groups, allow/disallow rules and sitemap declarations.

Quick guide

How robots.txt works

robots.txt is a crawler instruction file at the root of a host. It can suggest which paths compliant crawlers should or should not request and can advertise sitemap locations.

robots.txt is not an access-control mechanism. A disallowed URL can still be reachable by anyone who knows the address, and search engines may sometimes know that a URL exists even when crawling is blocked.

User-agent

Starts a rule group for one crawler name or * for a broad group.

Disallow / Allow

Describe paths a compliant crawler should avoid or may crawl.

Sitemap

Points crawlers at one or more XML sitemap files.

How it works

IPGetter fetches the public robots.txt file, parses user-agent groups, Allow and Disallow directives, and any Sitemap declarations it contains.

Useful when
  • Checking whether crawlers are blocked
  • Finding declared sitemap URLs
  • Reviewing robots.txt after a deployment
