Duplicate, submitted URL not selected as canonical

Hello,

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

Could you check if these URLs are AMPs? If not, check the advanced tab to see if you have changed the canonical and check if the actual URL and the canonical have some sort of variation – HTTP or HTTPS, trailing slash or not:
https://rankmath.com/kb/advanced-tab/#canonical-url

For indexing, can you also ensure that Search engine visibility in WordPress Dashboard > Settings > Reading is unchecked?

If the issue persists, please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section for us to further investigate.

It is completely secure and only our support staff has access to that section. If you want, you can use the below plugin to generate a temporary login URL to your website and share that with us instead:

You can use the above plugin in conjunction with the WP Security Audit Log to monitor what changes our staff might make on your website (if any):

Please do take a complete backup of your website before sharing the information with us.

We really look forward to helping you.

Hello,

I’ve checked your site and your page seems to have the canonical set correctly, so this should not be an issue. Rank Math automatically adds a self-canonical to all pages set to Index unless changed in Rank Math meta box while editing the page under the advanced tab.

I’ve already flushed your sitemap, and also, please clear your website cache. After that, please resubmit the URL to the Google Search console and give it time to recrawl your website.

Please note that it is completely upto Google if they want to index or not index your website. If you haven’t willingly or accidentally made your posts, noindex and Google still aren’t indexing your page – it means that either Google doesn’t want to index or hasn’t crawled your page yet because it hasn’t allocated that much crawl budget to your website.

Please check this website for more details.

I hope that helps, and please do not hesitate to let us know if you need our assistance with anything else.
