Could it be that you haven’t enabled the ‘Prevent search engines from indexing this site’ option in Settings -> Reading?
Hello,
Thank you for contacting Rank Math and sorry for any inconvenience that might have been caused due to that.
Can you please share the URL of the pages you are having this issue with so we can further assist you?
Several settings in WordPress and Rank Math control the indexing of posts and pages. You need to make sure that these settings are configured correctly.
Please check WordPress Dashboard > Rank Math > Title & Meta > Post/Page and confirm that the Robot meta is set to index.
Lastly, you should also check this specific page/post and ensure that it is set to index.

Let us know how that goes and don’t hesitate to get in touch if you have any other questions.
Thank you.
