Hello,

Thank you for contacting Rank Math.

Here is a code that will loop your posts and insert a keyword from the post type’s title:

function update_focus_keywords() {
	$posts = get_posts(array(
		'posts_per_page' => -1, /* -1 will retrieve all post type */
		'post_type' => 'post' /* post, page, product */
	));
	foreach($posts as $p){
		update_post_meta($p->ID,'rank_math_focus_keyword',strtolower(get_the_title($p->ID)));
	}
}
add_action( 'init', 'update_focus_keywords' );

Do note that this configuration will loop ALL your post. Modify this code as per your preferences.

Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
