# Free HTTP Header Checker - Security & SEO Headers

> Paste any URL to fetch live response headers. Review status, timing, HSTS/CSP and related security headers, plus SEO signals like X-Robots-Tag - no signup.

```yaml
url: "https://www.scrolllaunch.com/tools/http-header-checker"
slug: http-header-checker
category: onpage
keywords: "http header checker, check http headers, security headers checker, x-robots-tag checker, hsts checker, response headers tool"
```

## How to use

1. **Paste a URL** - Enter https://example.com or a deep path you care about.
2. **Inspect headers** - We fetch the URL, follow redirects, and list every response header plus a security checklist.
3. **Fix gaps** - Add missing HSTS/CSP (carefully) and confirm X-Robots-Tag is not blocking indexation.

## Which HTTP headers matter before launch

Security headers (HSTS, CSP, X-Content-Type-Options, frame controls) reduce common browser attacks and are often checked in directory and enterprise reviews.

X-Robots-Tag can noindex a URL even when the HTML looks fine - always verify headers on staging vs production before you submit directories.

Pair this checker with the redirect and canonical tools so the final URL you promote has the headers you expect.

## What you get

- Full response header table
- Security header checklist
- X-Robots-Tag & cache signals
- Follows redirects to the final URL
