HTTP Header Checker
Analyze live response headers to find crawl, caching, and indexation signals that need attention.
Why this matters and usage tips
HTTP headers control how crawlers and browsers interpret a page. Wrong directives or missing cache controls can damage visibility, crawl efficiency, and performance.
- Status codes: confirm the response resolves as expected before you inspect on-page SEO.
- X-Robots-Tag: server-level indexation directives can override what teams expect from page markup.
- Caching headers: missing cache directives often point to avoidable performance drag.
- Content-Length: unexpectedly large payloads can hint at assets or responses worth optimizing.
Steps:
- Enter the full URL and run the checker.
- Review the returned header table for status code issues, crawl directives, and caching policy.
- Share the copied output with engineering if response behavior does not match the intended SEO policy.
- Adjust server or CDN configuration when you find noindex directives, missing cache control, or abnormal payload clues.
