Technical SEO / http-headers
HTTP headers checker
Inspect crawl and security headers on the wire
Headers can noindex a page (X-Robots-Tag), force HTTPS, or tell caches how long to keep HTML. They also show Server, Content-Type, and common security policies. This is the response Googlebot sees, not the rendered DOM.
What this checks
- Status, server, and Content-Type
- X-Robots-Tag and cache headers
- HSTS, CSP, X-Frame-Options, and related security headers
- The full header list
Why it matters
A meta robots tag in HTML and an X-Robots-Tag on the response can disagree. Caching HTML too aggressively can serve stale titles. Check the wire.
