Setting minimum word count for WordPress posts

By default, WordPress does not enforce a minimum word count for posts. If your site accepts content from multiple authors, you may want to ensure posts meet a minimum length for quality and SEO purposes. On ruachost.com, you can enforce this by adding a simple PHP function.

Why Set a Minimum Word Count?

• Ensures consistent content quality.

• Helps with SEO by avoiding thin content.

• Encourages authors to provide more detailed posts.

Steps to Add Minimum Word Count Rule

1. Log in to WordPress with an administrator account.

2. In the dashboard, go to Appearance → Theme Editor.

3. From the right‑hand column, select the file named functions.php.

4. Scroll to the bottom of the file and add the following code:

   function minWord($content) {
       global $post;
       $content = $post->post_content;
       if (str_word_count($content) < 100) { // set minimum word count here
           wp_die(__('Error: Your post is below the minimum word count. It needs to be longer than 100 words.'));
       }
   }
   add_action('publish_post', 'minWord');
   

    

5. Click Update File to save changes.

✅ Now, if a post has fewer than 100 words, WordPress will display an error message and prevent publishing.

Important Notes

• Always back up your theme files before editing.

• Consider using a child theme to preserve changes during updates.

• You can adjust the number 100 to any minimum word count you prefer.

• This rule applies only when publishing posts, not drafts.
