X-Robots-Tag does the same job as the robots meta tag but travels in the HTTP response, so it is invisible in the page source. A page can look perfectly indexable while the server quietly forbids it.
Remove the noindex directive from the X-Robots-Tag header in the web server or application config.
Check a page for this, and the other 75 checks at once
Page has a meta description
The meta description is the snippet under the title in search results. Without one Google assembles a snippet from whatever text it finds, which is often a navigation menu or a cookie banner.
No insecure subresources
An https page that pulls scripts, styles, or images over http has those requests blocked or downgraded by the browser. Layout and behaviour break with no server-side error to show for it.
robots.txt lets Google crawl the page
A Disallow rule in robots.txt stops Googlebot from fetching the page at all, so everything else on this report stops mattering: the page can only appear in results as a bare URL with no description, or not at all.
Page has exactly one H1
The H1 states what the page is about. Zero leaves the topic unstated; several compete with each other and make the page read as a list of unrelated sections.
