What does a robots.txt tester do?
It checks whether a specific URL is allowed or blocked for a chosen crawler, shows the strongest matching rule, and helps you validate live or draft robots.txt files before they create crawl issues.
Robots.txt Tester
Test whether a URL is crawlable for a specific bot, inspect the strongest matching rule, and validate live or draft robots.txt files before they ship.
Robots Rules TestPublic HTTP/HTTPS only
This is the exact URL path the bot is trying to crawl.
Optional. Leave blank to fetch /robots.txt from the tested URL's origin.
Use a crawler token like Googlebot, Bingbot, or *.
Live mode fetches the public robots.txt file and tests one URL against it.
What this tester checks
- The strongest matching Allow or Disallow rule for the exact path.
- User-agent specificity, including wildcard fallback behavior.
- Missing robots.txt responses, unsupported directives, and malformed ordering.
- Sitemap lines and crawl-delay values that may affect broader crawl operations.
Best use cases
Check launch-day crawl blockers before a redesign or migration goes live.
Test draft rules manually before you deploy a new robots.txt file.
Verify that staging, search, admin, or faceted URLs are blocked without hiding revenue pages.
Reminder
A missing robots.txt file usually means full crawl access, but that does not guarantee correct indexing. Pair this with your redirects, canonicals, and XML sitemap checks.
Start with the exact URL you want search engines to crawl, then test the live file or paste a draft robots.txt file before release. The goal is to confirm that important pages stay open while low-value or private paths stay closed.
- Use live mode when you need to confirm what is already in production.
- Use manual mode before launch, migration, or template changes that affect crawl controls.
- Check exact paths for search results, faceted filters, admin areas, and high-value landing pages.

Can robots.txt remove a page from Google?
Not reliably. Robots.txt controls crawling, not indexing. A blocked URL can still appear in search if Google discovers it from links or other sources.
Should I block faceted URLs, admin paths, or internal search pages?
Often yes, but only after confirming those sections are not meant to rank and are not needed for core user journeys. Test the exact paths before deploying the rule.
