Focus Keyword

Hello, I understand that you want to automatically use the product title as the Focus Keyword for your products. To achieve this, you can add the following code snippet to your theme’s functions.php or rank-math.php file:

/**
 * Function to automatically update the focus keyword with the post title
 */
function update_focus_keywords()
{
    $posts = get_posts(array(
        'posts_per_page'    => -1,
        'post_type'        => 'product' //replace product with the name of your post type
    ));
    foreach ($posts as $p) {
        update_post_meta($p->ID, 'rank_math_focus_keyword', strtolower(get_the_title($p->ID)));
    }
}
add_action('init', 'update_focus_keywords');

Please note that this code will replace all your existing focus keywords. If you wish to set the post title as a focus keyword only for the products that don’t have a focus keyword set, then you may use a slightly modified version of the code.

Once you’ve added the code, it will automatically update the focus keyword with the product title. Here’s a screenshot to guide you on where to add the code in the Theme File Editor:

I hope this helps! If you have any further questions or need assistance with anything else, feel free to ask.
