How to customize the title for woocommerce shop page

The Shop page for WooCommerce is generated automatically and overrides the page that you choose for displaying products. The thing is the <title> of the Shop page always equals “Products – Your site name”, no matter what title your selected page has.

Some time we might want to change the <title> from “Products” to something different, e.g. “Catalog” or “My Store”. And we can do it using add_filter() function.

/**
 * Change the Shop archive page title.
 * @param  string $title
 * @return string
 */
function wc_custom_shop_archive_title( $title ) {
    if ( is_shop() && isset( $title['title'] ) ) {
        $title['title'] = 'My Store';
    }

    return $title;
}
add_filter( 'document_title_parts', 'wc_custom_shop_archive_title' );
