Category: SEO ToolsTool Name: HTTP Header Checker

Why Check HTTP Headers?

HTTP headers provide important information about how your server responds to requests. They include security headers, cache control, content type, and server information. Analyzing headers helps identify security issues, performance optimizations, and SEO-related configurations.

Important Headers for SEO

  • Status Code: 200 (OK), 301/302 (redirects), 404 (not found), etc.
  • Content-Type: Ensures proper content encoding
  • Cache-Control: Controls caching behavior
  • X-Robots-Tag: Can control indexing (alternative to robots.txt)
  • Canonical: Link header for canonical URLs

Security Headers

Check for security headers like HTTPS, HSTS (Strict-Transport-Security), X-Frame-Options, X-Content-Type-Options, and Content-Security-Policy. These protect your site and users, and can indirectly impact SEO by improving trust signals. Proper header configuration is essential for both security and performance.
