No deafult canonical on page

Hello,

I apologize for the inconvenience you’re experiencing with the canonical URL on your staging site. It seems that the default canonical self-reference is not appearing as expected when using Rank Math on the staging site, while it is present when using Yoast SEO on the live site.

To address this issue, you can easily set the canonical URL using Rank Math. You can navigate to the Advanced tab in the Rank Math meta box and change the Canonical URL field to point to the main source of your content. This will inform search crawlers of the main page if you have pages or posts with similar content.

Here’s a reference screenshot for setting the Canonical URL in Rank Math:

Once you’ve set your Canonical URL, simply update the page as you normally would after making a change or click Publish if it is a newly created page.

If you need further assistance with this, please feel free to reach out to our support team directly from here, and we’re always here to help.

Thank you for bringing this to our attention, and we appreciate your patience as we work to resolve this issue for you.

Hello,

Thank you for your patience.

Please note that Rank Math only adds the canonical tag if a page is set to index.

Once you have applied Rank Math to your site, a self-referencing canonical URL will be shown as well to your pages.

Hope that helps.

Hello,

When the WordPress Reading setting is set to discourage search engines from indexing the site, Rank Math will noindex the entire site, including individual pages – regardless of the individual index settings.

So to test this, you can temporarily untick the Search engine visibility checkbox and clear your cache to see if it works.

Let us know how it goes.
