LLM Discoverability

Strong security headers (CSP, HSTS, X-Frame-Options) indirectly signal to AI systems that the site is professionally maintained. They don't affect content extraction but contribute to overall domain trust.

SEO Impact

HTTPS and security headers are part of Google's page experience framework; sites with strong security signals are treated as more trustworthy, particularly in YMYL categories.
