What is a robots.txt tester?
A robots.txt tester helps you inspect and understand how crawlers may interpret your robots.txt rules.
This tool is useful for reviewing user-agent blocks, allow/disallow directives, and the overall structure of your robots.txt file.
How to use the Robots.txt Tester / Generator
- Paste your robots.txt content into the input field.
- Click Analyze to parse the directives.
- Review the generated output.
- Use the example button if you want to start with a sample file.
Tips
- Use specific user-agent rules when different bots need different crawl access.
- Keep robots.txt simple and avoid contradictory allow/disallow rules.
- Remember that robots.txt does not guarantee private content protection.
- Add your sitemap URL when appropriate.
Common robots.txt mistakes
Blocking assets needed to render pages
Do not block CSS, JavaScript, or image assets that search engines need to understand important pages.
Using robots.txt for private content
robots.txt is public and advisory. Use authentication or authorization for content that must not be accessed.
Confusing noindex with disallow
A disallowed page may still be known from links. Use noindex on crawlable pages when you need removal from search results.
Forgetting the sitemap directive
Adding a Sitemap line helps crawlers discover canonical URLs, especially on larger or recently changed sites.

Robots.txt checks before blocking crawlers
Robots.txt can guide crawlers, but it is easy to block important pages by accident. Test specific URLs before deploying rules.
Important URLs
Test homepage, category pages, tool pages, sitemap URLs, assets, and locale paths against the rules you plan to publish.
User-agent scope
Confirm whether a rule applies to all crawlers or only to a named user-agent group.
Sitemap discovery
Include the correct sitemap URL so search engines can find canonical pages faster.
No privacy guarantee
Do not use robots.txt to hide private data. Blocked URLs can still be visible if linked or known elsewhere.
