How to add the filter in rankmath plugin

Hello,

Thank you for contacting Rank Math today.

To be able to use any of the listed filters on the referenced page, you will only need to copy the snippet and paste it on your child theme’s functions.php file. Most of the filters will however require additional modification to suit the use case.

Here is an example:

/**
 * Change the Focus Keyword Limit
 */
add_filter( 'rank_math/focus_keyword/maxtags', function() {
    return 8; // Number of Focus Keywords. 
});

The code above will increase the keyword limit to 8 and you can change this value to any other preferred number.

Looking forward to helping you. Thank you.
