Frequently asked questions
What HTTP headers will this tool show me?
It displays the response headers a server returns for the URL, such as Content-Type, Cache-Control, Server, Content-Security-Policy, and others, along with the status code and response time.
Why are HTTP headers useful for SEO and debugging?
Headers reveal caching rules, redirects, content type, compression, and security policies, which help you diagnose indexing issues, verify HTTPS and caching, and confirm a server is configured correctly.
Why does the URL need to include https://?
The tool needs a complete, valid address to make the request; entering the full URL with the scheme ensures it targets the correct protocol and returns accurate headers.
Why might a fetch return an error?
Some servers block automated requests, are unreachable, require authentication, or respond in an unexpected format; the tool reports the status and error so you can adjust the URL and retry.
Is the tool free, and is the URL processed privately?
It is free with no registration. Because browsers block cross-origin header requests, the URL is fetched through our server proxy, so the public address you enter is requested by our server to read its headers; no login or personal data is required.
