Hello,
Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.
It looks like the tag page URL you’ve shared is empty. In this case, if you want to set index this tag page, please head over to your WordPress Dashboard > Rank Math > Titles & Meta > Global Meta, and from there disable the Noindex Empty Category and Tag Archives option:

Hope that helps and please don’t hesitate to let us know if you have any other questions.
Thank you.
Thanks for the response, after writing to you I found that it’s better to no-index an empty page, right?
Additionally, do you know why no-index excludes Google search console reporting since we control indexing and Google sees it as an issue?
Hello,
That is correct. In this case, adding a noindex
to blank pages will help so that they don’t count toward your SERP ranking in a negative way.
As for the other question, Google found and crawled that URL but didn’t index it. The only time this will be an issue is if the pages you want to be indexed are being marked as no-index. So the report you see is something you can safely ignore.
Hope that helps and please do not hesitate to let us know if you need my assistance with anything else.
