How to Remove the “Website” Field from the WordPress Comment Form

By default, WordPress includes a “Website” or “URL” field in its comment form. While this may be useful in some cases, it often attracts spammers who leave low-quality comments just to insert backlinks. If you’re looking to reduce spam and keep your comments section clean, removing the URL field is a simple and effective step.

You can do this easily by adding a small PHP snippet to your theme’s functions.php file. Here’s the code you need:

// functions.php

function remove_comment_url_field($fields) {
    if (isset($fields['url'])) {
        unset($fields['url']);
    }
    return $fields;
}
add_filter('comment_form_default_fields', 'remove_comment_url_field');

This function uses the comment_form_default_fields filter to remove the url input from the default comment fields. After you add this code and save the file, the “Website” field will no longer appear in your comment form.

This small adjustment can help discourage spammy behavior and improve the quality of engagement on your site. Visitors will still be able to leave their name, email, and comment — but without the temptation of promoting their website.

Just be sure to add this code in a child theme or custom plugin if you want to preserve the change when updating your theme. This method is lightweight, effective, and doesn’t require any additional plugins.
