the X-Robots-Tag HTTP header
An HTTP response with an X-Robots-Tag instructing crawlers not to index a page can be in direct contradiction to the meta tag on page. In those cases crawlers are supposed to follow the stricter noindex directive. Consider the following example:
<meta name="robots" content="index, follow" />
X-Robots-Tag: noindex
Google Search Console URL Inspection will declare this Excluded by ‘noindex’ tag
