Automatically Use the Post Title as the Focus Keyword

Hello,

Thank you for contacting Rank Math and bringing your concern to our attention.

Could you please try this filter to get the first three words from your title and set them as focus keywords?

/**
 * 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) {
        $trimmed_title = wp_trim_words(strtolower(get_the_title($p->ID), 3, ''));
        update_post_meta($p->ID, 'rank_math_focus_keyword', $trimmed_title);
    }
}
add_action('init', 'update_focus_keywords');

The filter should be added to your active theme’s functions.php file. Here’s another way to apply the filter using the rankmath.php file:

I hope that helps.

Thank you.

Hello,

Please try this filter instead:

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) {
        $trimmed_title = wp_trim_words(get_the_title($p->ID), 3, '');
        update_post_meta($p->ID, 'rank_math_focus_keyword', strtolower($trimmed_title));
    }
}
add_action('init', 'update_focus_keywords');

Let us know how that goes. Looking forward to helping you on this one.
