About This Check
Checks whether the X-Robots-Tag response header contains noai, blocking AI systems at the HTTP header level.
Why This Matters
LLM Discoverability
Delivering AI opt-out signals at the HTTP header level means they apply before the document body is even parsed, offering the earliest possible restriction on AI content use.
SEO Impact
Like meta noai, header-level noai has negligible direct SEO impact but can create unintended signal conflicts if inconsistently paired with other directives.
