HTTP Header Checker

Inspect status code, content type, cache headers, x-robots-tag, redirects, and security headers.

How it works

Using the HTTP Header Checker

  1. Paste the full URL you want to check above.
  2. CrawlVitals fetches the live page and reads its real response — headers, HTML, metadata, and signals — exactly as a crawler would.
  3. You get a plain-English result showing what passed, what needs attention, and the specific fix.
Why it matters

Technical in plain English

Technical signals — status codes, redirects, headers, and rendering — decide whether a page is served cleanly to crawlers. Small misconfigurations here can suppress an otherwise healthy page.

The HTTP Header Checker focuses on one job. Inspect status code, content type, cache headers, x-robots-tag, redirects, and security headers. That keeps the check fast and unambiguous, so you can fix the issue and move on instead of reading a generic SEO report.

The checks behind this tool follow published guidance from Google Search Central.

Free, no signup

Runs in your browser. Nothing to install and no account required to get a result.

Same engine as the app

Built on the same rules the full CrawlVitals scanner uses across crawl, indexability, GEO, and AI-readiness.

Built to act on

Every result points at the specific fix, so it becomes a change you can ship — not just a number.

FAQ

Common questions

Is the HTTP Header Checker really free?

Yes — it runs with no signup or payment. When you need scheduled scans, full-site coverage, and monitoring over time, the CrawlVitals app picks up where the free tools stop.

Is this a real check or a guess?

It's a real check. The HTTP Header Checker fetches the live page and reads its real response and applies CrawlVitals' actual rules — not a canned template.

Will it guarantee indexing or rankings?

No tool can. The HTTP Header Checker helps you remove the technical reasons a page gets ignored; search engines and AI systems still decide what to index, rank, or cite.

What do I do with the result?

Apply the fix it points to, then re-check. For the full picture, run a complete site scan or explore the other free tools.
