How the Robots.txt Tester works
Paste your robots.txt content into the text area — there's no live URL fetch, so copy the raw file content first.
Enter a URL path to test (e.g. /admin/login) in the path field.
Type a user-agent to simulate (e.g. Googlebot, Bingbot, or * for all crawlers) in the free-text agent field — leave blank to default to *.
Click Test Path to see whether that path is allowed or disallowed, using Google's longest-match precedence rule.
Tips & tricks
- There's no live URL fetch and no batch mode — paste robots.txt content manually and test one path at a time.
- The user-agent field is free text, not a dropdown — type exactly the agent name you want to simulate (e.g. Googlebot), or leave it blank for the * wildcard.
- The tool applies Google's longest-matching-rule precedence, not Bing's first-match precedence — results may differ from Bing's actual behavior for overlapping Allow/Disallow rules.
- Sitemap: lines in your robots.txt are parsed and shown in the summary panel alongside the total rule count and detected user-agents.
Frequently Asked Questions
Can I enter my site's robots.txt URL instead of pasting its content?
No — this tool only parses text you paste in directly. Visit your robots.txt URL, copy its contents, and paste them into the text area.
How does the robots.txt tester work?
The tester parses your pasted robots.txt content, identifies the rules applicable to the user-agent you typed, and evaluates the path against those rules using the longest-matching-rule wins precedence — returning Allowed or Disallowed.
What is the order of precedence for Allow vs Disallow rules?
Google uses the most specific rule (longest matching path), which is what this tool implements. Example: Disallow: /private/ and Allow: /private/public/ — the Allow rule wins for /private/public/page because it's more specific. Bing uses the first matching rule instead, which this tool does not replicate.
Can I test multiple URL paths at once?
No — there's no batch test mode. Test one path at a time by changing the path field and clicking Test Path again.
Does a Disallow rule prevent a URL from appearing in search results?
Not necessarily. Disallowing a URL prevents Googlebot from crawling it, but if other sites link to it, Google may still index it with limited information. To fully prevent indexing, use a meta robots noindex tag on the page itself.
Is my data safe when using the Robots.txt Tester?
Completely safe. The Robots.txt Tester processes everything locally in your browser. No input data, results, or usage information is ever transmitted to or stored on any server.
How current is the data returned by the Robots.txt Tester?
The Robots.txt Tester fetches live data in real time each time you run it. Results reflect the current state of the server or domain at the moment of the request.
Why does the Robots.txt Tester sometimes return different results than other tools?
Results depend on the real-time state of the target server and DNS propagation, which can vary by geographic region and caching TTL. If you see inconsistencies, wait a few minutes and re-test — DNS changes can take up to 48 hours to propagate fully worldwide.
