HTTP header checker
Enter a URL to see its status code and headers, and check for a noindex header.
What this checks
Fetches the URL and shows the status code, the X-Robots-Tag header and five common security headers.
How to fix common problems
- Make sure important pages return status 200.
- Remove any X-Robots-Tag noindex from pages that should rank.
- Add HSTS and X-Content-Type-Options for basic protection.
Common questions
What does X-Robots-Tag do?
It sends indexing instructions in the HTTP header, such as noindex, instead of in the page HTML.
Are security headers a ranking factor?
Not directly, but they protect visitors and show a well-maintained site.
