Robots.txt Generator & Tester

Build a standards-shaped robots.txt with multiple user-agents, then test URLs to see whether your rules allow or block them — longest matching rule wins (Google-style).

Googlebot generally ignores crawl-delay; Bing may honor it.

Robots.txt tester

Paste a path like /pricing or a full URL — we use the pathname only. Pick which user-agent to emulate.

Features built for real crawl management

  • Multiple user-agent groups with independent Allow and Disallow lists.
  • Live preview, one-click copy, and downloadable robots.txt for fast deployment.
  • Path tester with explicit verdict, matched rule text, and originating block label.
  • Optional sitemap URL and crawl-delay fields with host-specific caveats called out.

How to use this tool

  1. Model each crawler family (for example * and Googlebot) in its own block.
  2. Add the narrowest Allow rules first when you need exceptions inside disallowed trees.
  3. Paste representative URLs from Search Console into the tester before you push live.
  4. Copy or download the file, upload it to your site root, and re-test with Fetch as Google/Bing.

Practical use cases

Staging environments, faceted ecommerce URLs, internal search result pages, and API documentation often need nuanced crawl controls. Pair this generator with your meta tag strategy so indexing signals stay coherent across HTML and plain-text directives.

Ship confident crawl rules

When redirects also change URL shapes, sketch them with the .htaccess redirect generator so bots encounter consistent patterns end to end.

Works great with these tools

When you block legacy URLs, pair rules with clean redirects using our free .htaccess redirect generator.

Frequently asked questions

Common questions people ask before using this tool.

What is robots.txt used for?

robots.txt is a plain-text file at your site root that gives crawlers Allow or Disallow instructions and can point them to your XML sitemap — it does not guarantee indexing, but guides polite bots.

Should robots.txt block CSS or JavaScript?

Usually no. Public CSS and JavaScript should stay crawlable so Google can render pages correctly for ranking and rich results.

Can robots.txt hide private data?

No. Sensitive content needs authentication. robots.txt only suggests what well-behaved crawlers should fetch.

Should I include a sitemap URL in robots.txt?

Yes. A Sitemap: line helps search engines discover important URLs faster, especially on large or new sites.
