Customizing filtered pages

Hello,

Thank you for contacting us.

Could you share a few example pages/links so that we can have a closer look?

Looking forward to helping you.

Thank you.

Hello,

We do not control the H1 tags on the page and hence dynamically modifying that with Rank Math would not be possible. You can get in touch with your theme developers regarding this.

However, for setting the page indexable, SEO title, and meta description, the below filters can be modified and used:
Set indexable: https://rankmath.com/kb/filters-hooks-api-developer/#change-robots-meta
SEO Title: https://rankmath.com/kb/filters-hooks-api-developer/#change-the-title
Meta Description: https://rankmath.com/kb/filters-hooks-api-developer/#change-meta-description

Here’s a sample code that you can further modify as per the requirement:

/**
 * Filter to change the page title.
 * 
 * @param string $title
 */
add_filter( 'rank_math/frontend/title', function( $title ) {
        if( strpos( $_SERVER['REQUEST_URI'], '/shoes/sandals/?size=43' ) ){
            $title = 'Custom Title';      //Modify the title text here
        }
	return $title;
});

This code modifies the SEO title of the URI /shoes/sandals/?size=43.

You can follow this guide to add the code:

Hope this helps.

Thank you.
