X-Robots-Tag HTTP header opts out of AI (noai / noimageai)

X-Robots-Tag is an HTTP response header, a piece of metadata your server sends with every page or file, that can carry the same opt-out directives as an on-page meta tag. This check found the header includes noai or noimageai on your site, an explicit instruction telling AI systems not to use the content or images for training. Unlike the on-page meta version, a header-level directive also applies to non-HTML files like PDFs and images, and it's frequently left on by accident, often set at the server or CDN (content delivery network) level by a security-hardening template rather than a deliberate business decision. If AI visibility is a goal, this header actively works against it. Your developer needs about 20 minutes. Check the X-Robots-Tag configuration at your web server or CDN and remove noai/noimageai if AI visibility is a goal. If the opt-out was a deliberate choice, for example to protect proprietary images, no action is needed.
