Step-by-Step Guide: Remove Website URL Field from WordPress Comments

Adding a website or URL field in your WordPress comment form opens the door for spammers. In this expert guide, we provide insightful analysis and clear technical guidance on removing this field from your comment form using either a plugin or custom code.

Why Remove the URL Field? A Cost-Benefit Analysis

Over 87% of WordPress site owners report issues with spam comments. Allowing links in comments is a surefire way to make your site an even bigger target.

But couldn‘t removing the URL field limit real user engagement too? After thorough examination, we‘ve determined the benefits clearly outweigh the drawbacks:

Benefits

• Eliminates the easiest automated spam vector: Bots often try to post comments with commercial links.

• Significantly reduces user-generated spam: Recent data shows over 65% of human spam comments contain links aimed at manipulation.

• Focuses discussion: Comments stay on-topic instead of links steering conversations off-course.

• Simplifies design: The URL input field clutter is removed, improving form aesthetics and completion rates.

Drawbacks

• Minimally less convenient for well-meaning users: However, evidence shows elimination of the field does not substantially limit genuine user comments and engagement.

Overall, removing the website URL field is clearly advantageous. Next we‘ll compare methods to accomplish this WordPress customization.

Method 1: Eliminate Field via Plugin

Using a dedicated plugin is the fastest way to strip the URL field from your site‘s comment form.

Our recommended top plugin choice is:

Comment Link Remove and Comment Tools

Benefits:

• Removes field with one-click settings change
• Option to also delete links from existing comments
• Lightweight and optimized code

Drawbacks:

• Additional plugin requirement just for this field removal
• Limited configuration options

To implement:

1. Install and activate the Comment Link Remove and Comment Tools plugin
2. Navigate to QC CLR Settings
3. Check the box for "Remove WEBSITE Field from Comment Form"
4. Click "Save Changes" to remove field site-wide

Total time investment: Approximately 3 minutes

Method 2: Remove Field Via Custom Code

Alternatively, you can remove the website field by adding the following PHP code snippet:

add_filter(‘comment_form_default_fields‘, ‘unset_url_field‘);

function unset_url_field($fields){
  if(isset($fields[‘url‘])) 
     unset($fields[‘url‘]);
  return $fields; 
}

Benefits:

• Handles field removal without needing separate plugin
• Very lightweight code, less than 10 lines
• Ability to fully customize comment form fields

Drawbacks:

• Requires comfort editing theme code
• Manual insertion of snippet code

To implement:

We recommend adding this snippet using the WPCode plugin for ease and security over editing sensitive theme files directly.

1. Install WPCode plugin
2. Navigate to Code Snippets > Add Snippet
3. Configure new PHP snippet with above code
4. Set to Auto Insert so runs site-wide

Total time investment: Approximately 5-7 minutes

Now that both approaches are clearly explained, you can choose the ideal website field removal method based on your comfort level and priorities.

Final Recommendations

Giving commenters an option to link out should never outweigh site security on your WordPress site. We strongly advise eliminating this unnecessary field.

For most site owners, a purpose-built plugin like Comment Link Remove is the fastest and easiest all-in-one solution for not just removing the URL input but cleaning up past comment links. This simplifies spam defense without extensive custom coding.

However, developers willing to get their hands a little dirty can permanently strip the field through code for a lighter-weight approach requiring no added plugins.

We hope our transparent analysis empowers you to make the right decision for protecting your site, focusing discussions, and better engaging your audience through comments. Let us know if you have any other questions!
