About this free robots.txt tester

A single robots.txt mistake can block your entire site from Google. Teams often discover accidental Disallow rules after traffic collapses.

This robots.txt tester loads your robots file for a domain and highlights directives that may prevent crawling of important paths.

What it checks

  • robots.txt availability at the site root
  • Disallow and Allow rules affecting common paths
  • Sitemap declaration in robots.txt

Why it matters for SEO

  • robots.txt controls crawler access at scale — faster than fixing noindex on hundreds of pages.
  • Staging or legacy rules copied to production are a frequent cause of indexing loss.
  • Proper sitemap references in robots.txt improve discovery.

How to use this tool

  1. Submit your site origin (e.g. https://example.com).
  2. Read which paths are allowed or blocked for generic crawlers.
  3. Adjust rules, deploy, and confirm Search Console shows expected crawl behavior.

Common issues we help you catch

  • Disallow: / blocking the whole site
  • Blocking /wp-admin/ but accidentally blocking assets needed for rendering
  • Missing Sitemap: line pointing to the XML sitemap

Frequently asked questions

Does robots.txt stop pages from ranking?
Blocked URLs should not be crawled; they typically will not be indexed. Use noindex on pages you want crawled but not indexed.
Should I block low-value URLs?
Yes — faceted search, cart, and admin URLs are common candidates. Avoid blocking CSS/JS needed for rendering.
