Free Robots.txt Checker

Check whether robots.txt is reachable and whether the site exposes crawl guidance and sitemap references.

Paste a full URL or enter a domain such as example.com. Results include technology evidence, quality checks, and a developer fix list.

Run one URL scan and get a complete report.

  • robots.txt status
  • robots.txt sample
  • Sitemap reference hint
  • Indexability warnings
How it works

The scanner fetches the public page, follows a limited redirect chain, collects headers/resources/HTML, applies self-owned detection rules, checks SEO/security/accessibility/performance signals, and returns evidence-backed fixes.

Private IPs, localhost, file URLs, and internal hostnames are blocked to reduce SSRF and abuse risk.
