HTTP Header Checker

Why This Matters & Usage Tips

HTTP headers provide key information about how browsers and search engine crawlers should treat your page. Issues like incorrect status codes or X-Robots-Tag settings can unintentionally block your content from search results or degrade performance.

• Status Codes: A 2xx code confirms the content is available, while 4xx or 5xx can cause your page to be dropped from indexing.
• X-Robots-Tag: Similar to <meta name="robots">, but set at the server level. It can override or complement meta tags.
• Caching Headers: Using Cache-Control or Expires can significantly improve load speed and user experience, indirectly boosting SEO.
• Content-Length: Large files can slow pages, impacting core web vitals and user satisfaction.

Steps:

1. Enter a complete URL (e.g., https://www.example.com) and click “Check Headers.”
2. Review the returned headers in the table. Look for suspicious codes, missing caching directives, or an X-Robots-Tag that might hamper SEO.
3. Copy the headers to share with your dev team or keep for reference.
4. Adjust your server configuration if you see noindex directives, lack of caching rules, or other issues that might hurt performance and visibility.
