Robots.txt & Sitemap Checker

Your robots.txt file is the first thing every search engine reads. A single wrong line — like Disallow: / — removes your entire site from Google. Blocking CSS or JavaScript files stops Google from rendering your pages, which quietly tanks rankings.

The Sitemap directive is just as important: it tells every crawler exactly where your XML sitemap lives, helping new pages get discovered and indexed faster. Run your domain through the checker after every site migration or redesign to catch accidental blocks before search engines do.
