Short answer
A robots.txt checker reviews crawl rules before a site is submitted or recrawled. It helps catch accidental full-site disallow rules, missing sitemap hints, invalid lines, and path blocks that can keep important public URLs from being crawled.

More Variations
Robots.txt checker for crawl QA
Use this before requesting indexing, launching a site, or troubleshooting pages that are discovered but not crawled. The checker keeps crawl rules, sitemap hints, and a path test together so the next fix is obvious.
Pairs with the on-page SEO checker
Run the On-Page SEO Checker for page-level content and metadata, then use this robots.txt checker to confirm that crawlers are allowed to reach the URL in the first place.
Do not hide secrets in robots.txt
Robots.txt is public. Use it for crawler guidance only, and keep private admin, customer, or sensitive files protected by authentication and server rules instead.
Tool guide
Robots.txt Checker: free online workflow
The Robots.txt Checker is built for people searching for robots txt checker, robots.txt checker, robots txt tester, and robots txt validator, and a fast way to use the result without a paid download step. It keeps the calculator, generator, or file workflow on the same page as the explanation, so the searcher can read the guidance and use the tool immediately.
Use it when you need a practical answer, export, document, or formatted file quickly. The page is designed as a focused landing page for seo tools searches: clear instructions first, the working tool above, FAQs below, and internal links to related tools when the next step belongs somewhere else.
For broader workflows, browse the SEO Tools category. That page groups the related tools together so users can move from research to action without returning to search results.

Frequently Asked Questions
What does this robots.txt checker test?▾
It checks user-agent groups, allow and disallow rules, sitemap directives, syntax warnings, and whether a chosen path is blocked for the selected crawler.
Can robots.txt remove a page from Google?▾
Not reliably. Robots.txt controls crawling, not indexing. Use noindex for pages that should not appear in search, and do not block pages you want Google to see before it reads noindex.
Should every robots.txt file include a sitemap?▾
It is a useful discovery hint. Add the full sitemap URL when the site has an XML sitemap you want crawlers to find.
What is a risky robots.txt rule?▾
Disallow: / is risky when applied to public search crawlers because it blocks crawling across the site. It can be intentional for staging sites, but dangerous on production.
Can I check a live robots.txt URL?▾
Yes. Enter a public robots.txt URL and the checker fetches it through FreelTools, or paste the file contents manually if the live file cannot be fetched.
