What triggers this issue?
This issue reports pages with "noindex" directive that show up in the search results.
Why is it important?
A "noindex" directive on a page is used to prevent search engines from indexing a page in search results. If a noindexed page receives organic search traffic, search engines might be missing this directive for some reason. Also, the page could have been "noindexed" by mistake just recently and needs your review.
How to fix it?
Review the URLs listed in this report.
If you added a "noindex" directive to your page recently, Google has probably not re-crawled it yet and has not updated its index.
Also, check that the page is not blocked from Google in the robots.txt file of your site, otherwise, the search crawler will not be able to see the change.
If the page is supposed to be indexable, remove the "noindex" directive. This directive can be found in the
<head> section of your page or in its HTTP response header.
