Google Search Console showing Indexed, not submitted to sitemap”.

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention. I’m sorry for the delay and for any inconvenience this issue may have caused you.

The “Indexed, not submitted in sitemap” status indicates that Google’s indexed URLs aren’t included in your XML sitemap.

I’ve already checked the affected URLs, and it seems that they are already included in your sitemap. In this case, please check this link for more troubleshooting steps:

For the /locations.kml , we released a quick Beta update you can try to see if that helps. This will be available on the upcoming update of Rank Math

If you activate Rank Math, please enable the Beta update by following this:
https://rankmath.com/kb/version-control/#beta-updates

If you are unable to see an update, please clear Rank Math’s transients from:
WP Dashboard > Rank Math > Status & Tools > Database Tools > Remove Rank Math Transients > Remove transients

Please also note that some options are only available when you enable the Advanced Mode in Rank Math. If it’s not showing, you must have chosen to use the Easy Mode. Please follow the steps in this link to switch to Advanced Mode:

Please clear the caches, server, and WordPress after updating.

You can disable the Beta updates once you update to the latest version and if the issue is fixed.

I hope that helps. Thank you, and please don’t hesitate to contact us anytime if you need further assistance with anything else.
