Archive Pages for Blogs are Canonicalised to the main blog page

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.

Rank Math adds a self-referencing canonical URL by default for your paginated pages.

However, if it is not working on your site, then you can try the following filter to force the self-referencing canonical URL of your blog pagination:

add_filter( 'rank_math/frontend/canonical', function( $canonical ) {
	global $wp;
	$current_slug = home_url( $wp->request );

	if ( is_paged()) {
		$canonical = $current_slug . '/';
	}
	return $canonical;
});

And here’s a guide on how you can add a filter to your website:

Hope that helps.

Thank you.

Hello,

If the code didn’t work on your website, we might need to take a closer look at the settings. Please edit the first post on this ticket and include your WordPress & FTP logins in the designated Sensitive Data section.

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

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):

We really look forward to helping you.
