Robots.txt Checker
Fetches and parses robots.txt, flags blocked important paths, validates syntax, and checks for common misconfigurations.
Note: Some checks require fetching external URLs, which may be blocked by CORS restrictions in the browser. For URLs that can't be fetched directly, try pasting the HTML source instead. Full functionality can be connected via a server-side API proxy.
Why this matters
Robots.txt controls which parts of your site search engines can crawl. A misconfigured robots.txt can accidentally block Google from crawling important pages — one of the most catastrophic SEO mistakes. This tool helps you catch issues before they impact your traffic.

No. Google needs to render your pages properly, which requires access to CSS and JavaScript files. Blocking these resources can prevent Google from understanding your page content and layout.
