Robots.txt Tester

Paste a robots.txt file, test user-agents against URL paths, and catch crawl rule mistakes before deployment.

About this tool

Test crawl directives before release so important pages stay accessible and non-indexable areas stay blocked intentionally.

Robots.txt Tester lets you paste a robots.txt file and test specific URLs against its rules to see whether each path would be allowed or blocked for a given user-agent. It parses wildcard patterns, respects user-agent specificity, and evaluates rules exactly as a compliant crawler would interpret them.

  • Parses robots.txt content and evaluates allow or disallow rules for a selected user-agent and path.
  • Lists detected sitemap directives and simple syntax warnings.
  • Shows which rule won the match so debugging crawl behavior is easier.

How to use Robots.txt Tester

Paste your robots.txt contents, enter one or more test URLs, and select the user-agent to simulate. The tool evaluates each URL against the applicable rules and shows the matching directive, so you can confirm that important pages are crawlable and sensitive paths are properly blocked.

When this tool is useful

  • Test whether important templates or folders are blocked before deploying robots.txt changes.
  • Check specific user-agents like Googlebot against directories or parameter patterns.
  • Audit client robots files quickly without opening a separate crawler or desktop SEO suite.

Practical tips

  • Test both wildcard and bot-specific groups because the specific group can override your assumption.
  • Do not rely on robots.txt to deindex pages already known to search engines. Use noindex or remove access.
  • Keep sitemap lines valid and up to date so discovery and crawl directives stay aligned.

Why people use this tool

An overly broad disallow rule can accidentally block critical pages from search engine indexing, while a missing rule can expose staging environments or admin paths to crawlers. Testing rules before deployment catches these problems in a safe environment instead of discovering them through lost traffic or exposed content.

Frequently asked questions

How does the robots.txt tester decide whether a path is blocked?

It compares matching allow and disallow rules, then applies the strongest matching rule based on path length and directive precedence.

Can I test Googlebot separately from the wildcard rules?

Yes. Enter a specific user-agent like Googlebot to see whether a more specific group changes the result.

Can I test how Googlebot would treat a specific URL path against my rules?

Yes. Enter a user-agent like 'Googlebot' and a URL path like '/admin/settings', and the tool will tell you whether the path is allowed or disallowed based on the rules you pasted.

Does the tester respect the order of Allow and Disallow directives?

The tester follows the same longest-prefix-match logic that Googlebot uses, where the most specific matching rule wins regardless of its position in the file.

Will the tester warn me if I accidentally block CSS or JS files needed for rendering?

Yes. The tool flags common mistakes like broad Disallow rules that inadvertently block static asset directories such as /assets/ or /static/, which can hurt how search engines render your pages.
