Question 1

What HTTP security headers should my website have?

Accepted Answer

The most important security headers are Strict-Transport-Security (HSTS), Content-Security-Policy (CSP), X-Frame-Options, X-Content-Type-Options, and Permissions-Policy.

Question 2

What happens if security headers are missing?

Accepted Answer

Missing headers leave your site vulnerable to attacks like clickjacking (missing X-Frame-Options), MIME sniffing (missing X-Content-Type-Options), and cross-site scripting (missing CSP).

Question 3

Do security headers affect SEO?

Accepted Answer

Not directly, but HTTPS enforced by HSTS is a Google ranking signal. Secure headers also build user trust, which can positively affect bounce rate and engagement.
