Robots.txt Tester

When to use this tool

Robots.txt mistakes can make entire sections harder to crawl. This tester fetches a site robots file, summarizes rules, surfaces sitemap declarations, and lets you test a path against crawler directives.

Practical tips

  • Test exact paths, including trailing slashes and parameter versions.
  • Check robots.txt after staging, migration, or security rule changes.
  • Remember that robots.txt controls crawling, not whether a URL can appear in search results.

Frequently Asked Questions

What happens if a site has no robots.txt?

Most crawlers treat the site as crawlable unless other signals block access. A missing file is not automatically an error.

Can robots.txt block all search engines?

It can request broad crawl blocking, but compliant crawlers choose to honor it. Sensitive content should not rely on robots.txt for security.

Why are sitemap lines important?

Sitemap directives in robots.txt give crawlers a convenient place to discover your XML sitemap locations.
