Frequently Asked Questions

What are security headers?

Security headers are HTTP response keys configured on your web server that instruct user browsers how to handle code execution, frame permissions, and transport security.

How do security headers impact search SEO?

Secure websites build user and crawler trust. Search engines prioritize secure, HTTPS-enforced platforms, making server headers vital for maintaining search rankings.

What is HSTS?

HSTS (HTTP Strict Transport Security) is a header that forces browsers to connect exclusively via secure HTTPS protocols, preventing SSL stripping and credential downgrade attacks.

What is the difference between X-Frame-Options and CSP frame-ancestors?

X-Frame-Options is a legacy header to block clickjacking, while CSP frame-ancestors is a modern, flexible directive that achieves the same goal with support for multiple domains.

How do I fix a missing X-Content-Type-Options header?

You can add `X-Content-Type-Options: nosniff` to your server config (e.g. via Nginx, Apache, or Cloudflare rules) to prevent browsers from executing non-JS files as Javascript.
