Automating Key Words

Hello,

Thank you for contacting Rank Math.

To use the code for the products, you only need to set the post_type to product in the code.

You can use this code to add the Product title as the focus keyword:

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

If you wish to set the product title as a focus keyword only for the products 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, if no focus keyword is set
 */
function update_focus_keywords() {
    $posts = get_posts(array(
    'posts_per_page'	=> -1,
    'post_type'		=> 'product' // Replace post with the name of your post type
    ));
    foreach($posts 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' );

Hope this helps.

Thank you.
