How it works What the Robots.txt Tester does

Tests a list of URLs against a pasted robots.txt file and flags common noindex-risk URL patterns, without needing to crawl the live site.

3 steps How to use the Robots.txt Tester

  1. Paste your list into the box above — one item per line, and the second list into its own box. Keyword exports, crawl exports and spreadsheet columns all work.
  2. Check the settings and adjust them to your job — the result updates as you type.
  3. Copy the result and paste it wherever it needs to go. Nothing is uploaded, so client and confidential data stay on your machine.

Use it to When to use the Robots.txt Tester

  • Check a new robots.txt file against real URLs before deploying it
  • Verify important pages aren't accidentally blocked after a migration
  • Flag common noindex-risk URL patterns during a site audit
