This error appears when a page has a noindex directive configured that prevents Google from showing it in search results. Here's what it means and how to assess whether it should really be that way.
A page with noindex cannot rank on Google under any circumstances. All the work invested in that content, the links pointing to it, and the accumulated authority are worthless if the page is blocked from search engines.
A user trying to reach this page from Google simply won't be able to find it. If the page has valuable content, that value stays locked away and never reaches the people who need it.
Although Google can crawl the page, it won't include it in its index. That means any relevant content it has will be completely out of reach for users searching on Google.
If this error showed up in your audit, here are the steps to leave it behind.
The noindex can be in the meta robots tag in the HTML or in the X-Robots-Tag HTTP header. Open the page source, look inside the <head> for the meta robots tag, and also check the HTTP response headers.
It isn't always an error. If the page has content that shouldn't appear on Google, it may make sense to keep it. If it's there by mistake, it needs to be removed. Review the page's purpose and check with whoever manages SEO if you're unsure.
If the page should appear in search results, remove the noindex directive from the meta robots tag and from the HTTP header if it's there too. You can do this through the SEO plugin you use (Yoast, Rank Math, etc.) or directly in the code.
Once noindex is removed, check in Google Search Console that the page is being indexed correctly and that there are no other restrictions blocking it.
