What does a robots.txt checker do?
A robots.txt checker fetches a domain's robots.txt file and reports whether it is reachable, what it allows crawlers to access, and whether it declares a sitemap. Pinglyra includes this in its SEO assessment and also flags an accidental noindex on the homepage, so you can be sure search engines can actually crawl and index the site.
robots.txt controls how search engines crawl your site. A missing file or an accidental broad Disallow can hide pages from search. This free checker reads it for you.
Why robots.txt matters
A misconfigured robots.txt can accidentally block search engines from important pages, or a missing one can leave crawlers without guidance. Either way it affects how your site is indexed.
- Guides how search engines crawl the site
- An accidental Disallow can hide key pages
- Should reference the sitemap
What this checker reports
- Whether robots.txt is reachable
- Whether it declares a sitemap
- Homepage noindex detection (meta + X-Robots-Tag)
