How many websites pass the Xrobots Noai check?
Based on 14 audited sites · Updated 2026-07-16
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.
What To Do Next
Every audited site in the current sample passes xrobots noai, so this check is currently a baseline expectation rather than a differentiator.
- Prioritize xrobots noai on templates that create many URLs, because one template fix can improve a large share of bot access & control plane.
- After changing the page, re-run the audit and compare the observed value for this check instead of relying on visual inspection alone.
- Use the 100% pass rate as a benchmark: if your site fails here, passing the check moves it closer to the visible majority of crawlable, AI-readable pages.
