Boosting your WordPress website's performance is crucial for providing a seamless user experience and securing higher rankings on search engines like Google. While cache plugins play a significant role in speeding up your site, there are additional manual steps you can take to further enhance its performance.

One common contact form plugin used on websites is Contact Form 7. We often enable reCaptcha in the plugin to protect the form from bot submissions. However, have you noticed that the plugin code is executed on every page, even on those where the form is not being used? If you haven't noticed yet, take a quick look at the bottom right of your screen, and you'll spot the reCaptcha icon there.

To optimize the loading of plugin files and only load them on the pages where the contact form is actually used, you can simply add the following code to your functions.php file:

function wpcf7_dequeue_redundant_scripts() {

$post = get_post();

if ( is_singular() && !has_shortcode( $post->post_content, 'contact-form-7' ) ) {

wp_dequeue_script( 'contact-form-7' );

wp_dequeue_style( 'contact-form-7' );

wp_dequeue_script( 'wpcf7-recaptcha' );

wp_dequeue_style( 'wpcf7-recaptcha' );

wp_dequeue_script( 'google-recaptcha' );

}

add_action( 'wp_enqueue_scripts', 'wpcf7_dequeue_redundant_scripts', 99
