Automatically Use the Product Title as the Focus Keyword

Hello,

Thank you for contacting us and sorry for any inconvenience that might have been caused due to that.

You can try to use the following filter on your website to set the product title as a focus keyword only for the products that don’t have a keyword:

/**
 * Function to automatically update the focus keyword with the product title, if no focus keyword is set
 */
function update_focus_keywords() {
     $products = get_posts(array(
        'posts_per_page' => -1,
        'post_type' => 'product' //replace post with the name of your post type
    ));

    foreach ($products as $p) {
        // Checks if Rank Math keyword already exists and only updates if it doesn't have it
        $rank_math_keyword = get_post_meta($p->ID, 'rank_math_focus_keyword', true);
        if (!$rank_math_keyword) {
            update_post_meta($p->ID, 'rank_math_focus_keyword', strtolower(get_the_title($p->ID)));
        }
    }
}
add_action('init', 'update_focus_keywords');
