replace focus keyword from category name in to post title

Hello, I’m sorry to hear that you’re experiencing an issue with changing the focus keyword from the category name to the post title. To automatically update the focus keyword with the post title, you can add a code snippet to your theme’s functions.php or rank-math.php file. Here’s the code snippet you can use:

/**
 * Function to automatically update the focus keyword with the post title
 */
function update_focus_keywords()
{
    $posts = get_posts(array(
        'posts_per_page'    => -1,
        'post_type'        => 'post' //replace post with the name of your post type
    ));
    foreach ($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 posts that don’t have a focus keyword set, then use the following code instead:

/**
 * Function to automatically update the focus keyword with the post title for posts without a focus keyword set
 */
function update_focus_keywords()
{
    $posts = get_posts(array(
        'posts_per_page'    => -1,
        'post_type'        => 'post' //replace post with the name of your post type
    ));
    foreach ($posts as $p) {
        if (!get_post_meta($p->ID, 'rank_math_focus_keyword', true)) {
            update_post_meta($p->ID, 'rank_math_focus_keyword', strtolower(get_the_title($p->ID)));
        }
    }
}
add_action('init', 'update_focus_keywords');

You can add this code to your theme’s file editor and save the changes. This should help you automatically update the focus keyword with the post title. If you have any further questions or need assistance, please feel free to reach out to our support team here.
