Robots.txt Checker
Check any website's robots.txt file, see exactly what's allowed or blocked, and spot common crawling mistakes — free, instant, no signup required.
Free & unlimited checks. Results are cached for 6 hours per domain to keep things fast.
Why Robots.txt Matters
This small text file controls which parts of your site search engines are allowed to crawl — a mistake here can quietly de-index your entire site.
Control Crawl Access
Disallow rules tell search engine bots which folders or pages to skip, helping you keep low-value or duplicate pages out of the crawl queue.
Sitemap Discovery
Listing your XML sitemap in robots.txt helps search engines find and crawl your important pages faster and more reliably.
The "Disallow: /" Trap
A single misplaced rule can block search engines from your entire site. This checker flags that specific mistake immediately.
Frequently Asked Questions
Is this robots.txt checker really free?
Yes — checking any domain's robots.txt file with this tool is completely free with no signup or usage limits.
What happens if a site has no robots.txt?
Without a robots.txt file, search engines assume everything is allowed to be crawled by default — this isn't necessarily a problem, just worth knowing.
What's a User-agent group?
Each "User-agent:" line starts a new set of rules that apply to a specific crawler (like Googlebot) or to all crawlers via the wildcard "*".
Does robots.txt stop pages from being indexed?
Not directly — it only blocks crawling. A blocked page can sometimes still appear in search results without its content if it's linked to from elsewhere; use a noindex tag to prevent indexing.
