Is CSP required for SEO?

No direct ranking rule requires CSP, but it is a core production security signal and part of the launch-readiness score.

Can I use unsafe-inline?

It works as a compatibility shortcut but weakens script protection. Prefer nonces or hashes when the framework and runtime support them.

Fix guide

A missing CSP finding means the browser received HTML without an enforceable Content-Security-Policy response header.

Answer first

Without CSP, injected scripts and compromised dependencies have a larger execution surface than they need.

Detail 01

Start with default-src 'self', object-src 'none', base-uri 'self', frame-ancestors, and a script-src strategy based on nonces or hashes.

Detail 02

Inspect the response headers, run in report-only mode if the site is complex, fix violations, and re-scan once the enforcing header is live.
