How to Remove the URL Field From WordPress Comments

WordPress’s default comment form includes three fields: Name, Email, and Website (URL). The URL field was originally intended to let commenters link to their own blog, a convention from the early days of WordPress when blog networks were common.

Today it is a spam magnet for a specific reason: link equity. A link from a real, indexed website passes a small amount of PageRank to the destination. Spambots are not leaving comments to express an opinion — they are placing links at scale across thousands of sites to improve their target domain’s authority in search results. The URL field is the easiest way to do this because it creates a published link without requiring the comment body to contain anything useful or get past spam filters.

Removing the URL field has two effects:

• It eliminates the primary incentive to submit spam comments. Bots targeting the URL field stop submitting once there is nothing to submit to.
• It reduces your moderation workload, since fewer spam comments are submitted in the first place rather than just caught after submission.

The trade-off is minor: genuine commenters who want to share their site can no longer do so via the comment form. In practice, most readers on content-focused sites do not use the URL field anyway. And those who do can always include a link in the comment body, where it will be moderated alongside the comment text.

WooCommerce note: If your site runs WooCommerce, product reviews use a separate comment template. The PHP method below also removes the URL field from WooCommerce product reviews. If you want to remove it from blog comments only and keep it on product reviews, use the plugin method, which gives you more granular control per form type.

The quickest way is to add a small function to your theme’s functions.php file. This method requires no plugin and the change takes effect immediately:

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

Add this to your functions.php file and the URL field will be removed from all WordPress comment forms on your site. The function hooks into the comment_form_default_fields filter and unsets the url key from the fields array before WordPress renders the form.

If the above filter does not work (some themes call a different hook), try the comment_form_fields filter instead — it fires later in the rendering pipeline and catches cases the default fields filter misses:

function scanwp_disable_comment_url_late($fields) {
    unset($fields['url']);
    return $fields;
}
add_filter('comment_form_fields', 'scanwp_disable_comment_url_late');

Use only one of these two functions, not both. The second filter is the fallback if the first does not remove the field.

A few notes:

• This only affects the default WordPress comment form. If you are using a third-party comment plugin (Disqus, Jetpack Comments, etc.), the plugin controls its own form fields.
• Existing comments that already have a URL stored are unaffected. The URL data remains in the database; it just will not be collected from new comments.
• If you are using a child theme, add the function to the child theme’s functions.php to avoid losing it on theme updates.
• On multisite networks: this function only affects the site whose functions.php you edited. To apply it across all sites in a network, add it to a must-use plugin (mu-plugins folder) so it loads for every site automatically.

If you are not comfortable editing PHP files directly, see Method 2 for a plugin alternative. You can also read about WordPress antispam plugins for a broader approach to comment spam reduction.

If you would rather not edit PHP files, a plugin like Comment Form Fields Editor (free on the official WordPress plugin repository) lets you control which fields appear in the comment form from the WordPress admin without any code.

To use it:

1. Install and activate Comment Form Fields Editor from Plugins > Add New.
2. Go to Settings > Comment Form Fields.
3. Locate the Website (URL) field and uncheck it or toggle it off.
4. Save. The field is immediately removed from your comment form.

This approach is fully reversible. You can turn the field back on at any time from the same settings screen. It is the better choice if you are managing a site for a client who may want to re-enable the field later without needing a developer.

Zero-plugin option if you have Yoast SEO: Yoast SEO includes a built-in toggle to disable comment URLs. Go to Yoast SEO > Site Settings > Site Features, scroll to the Comments section, and look for the “Comment author URLs” toggle. Switching this off removes the URL field sitewide without installing anything extra. This is the fastest path if Yoast is already active on your site.

Other plugins that include comment form field control:

• Jetpack: Replaces the comment form entirely with its own system. The URL field behavior depends on Jetpack’s own settings, not WordPress defaults.
• Security plugins (Wordfence, iThemes Security): Some include comment spam options, but few offer field-level control. These are better suited to blocking spam submissions after the fact rather than removing the URL field specifically.

For most sites, either the PHP snippet or Comment Form Fields Editor is the right tool. The PHP approach is permanent and requires no plugin management; the plugin approach is better when you want a toggle you can control from the admin panel.

If your site uses a Block Theme (introduced in WordPress 5.9) and the Full Site Editor rather than a Classic Theme, the standard PHP snippet still works for the comment form, but there is an important difference to be aware of.

Why this matters for Block Themes:

Block Themes render the comment form through a block-based template, typically the comments.html template part in your theme’s /templates/parts/ folder. The comment_form_default_fields filter still fires and still removes the URL field from the PHP-rendered output. However, some newer Block Themes override the comment block with a custom block implementation that may not go through the standard filter at all.

How to check whether the PHP snippet is working in your Block Theme:

1. Add the PHP snippet to your active theme’s functions.php or a site-specific plugin.
2. Navigate to any post on your site that has commenting enabled.
3. Scroll to the comment form. If the Website field is gone, the snippet worked.
4. If the field is still showing, your theme is using a custom block for comments. In that case, proceed to the Site Editor steps below.

Removing the URL field directly in the Site Editor:

1. Go to Appearance > Editor in your WordPress admin to open the Full Site Editor.
2. In the left navigation, click Patterns, then find the Comments template part (it may also be listed under Templates).
3. Click into the Comments template part to edit it.
4. Click on the comment form area. You should be able to select a Comment Form block or a Post Comments Form block.
5. Inside that block, look for an Author URL field block or a block labeled “Website.” Click it to select it.
6. Press Delete or use the block’s three-dot menu and choose Remove block.
7. Click Save to apply the change to the template.

For themes like Twenty Twenty-Four, Twenty Twenty-Five, or Kadence’s block theme, the PHP snippet approach works without issue. You only need the Site Editor route if the PHP snippet leaves the field visible after adding it.

Plugin alternative for Block Themes:

The plugin approach (Comment Form Fields Editor) typically works with Block Themes because it hooks into the same filter. But if the theme bypasses standard WordPress filters entirely, the plugin will not work either. In that situation, editing the block template directly in the Site Editor is the most reliable fix.

After making the change with either method, do a quick verification before considering the task done.

Verify the URL field is removed:

1. Open your site in a private/incognito browser window. This ensures you are not seeing a cached version of the form.
2. Navigate to any published post with comments enabled.
3. Scroll to the comment form. The Website field should be absent. The form should show only Name, Email, and the comment text area.
4. Right-click the comment form and choose Inspect Element. Search the form’s HTML for id="url" or name="url". If those attributes are gone, the field has been removed at the HTML level, not just hidden with CSS.

What to expect from your spam queue afterward:

Most sites see a drop in spam comment submissions within 24 to 72 hours. The reduction is not always immediate because some spam networks cache target URLs and keep submitting for a short period even after the field disappears. After about a week, the volume typically drops to near zero for the lowest-effort bot traffic.

Akismet and similar tools still catch the small amount of keyword-stuffed spam submitted through the comment body. Removing the URL field does not eliminate all spam, but it removes the category that was specifically targeting your site for link building.

Cleaning up existing comments that have spam URLs:

The removal methods above stop collecting new URL data, but they do not touch URLs already stored in your database. If you want to clean those up:

Using phpMyAdmin:

1. Log into phpMyAdmin via your hosting control panel.
2. Select your WordPress database.
3. Click SQL and run: SELECT comment_ID, comment_author, comment_author_url FROM wp_comments WHERE comment_author_url != '' LIMIT 100;
4. Review the results. To clear a specific URL: UPDATE wp_comments SET comment_author_url = '' WHERE comment_ID = [ID];
5. To clear all stored URLs in one pass (use only if you are certain you want this): UPDATE wp_comments SET comment_author_url = '' WHERE comment_author_url != '';

Using WP-CLI (faster for large sites):

wp comment list --fields=ID,comment_author_url --format=csv | grep -v "^ID" | grep -v ",,$"
# Then to clear all:
wp db query "UPDATE wp_comments SET comment_author_url = '' WHERE comment_author_url != ''"

Database cleanup is optional. It only matters if you have a large number of approved comments with spam URLs that are still pointing to low-quality sites. For most sites, simply removing the field going forward is sufficient.
