Remove Yoast SEO Comments in WordPress page source

Do you want to remove the comments printed by the Yoast SEO plugin in the page source? Well, this tutorial will explain how to remove Yoast SEO comments from WordPress pages. Yoast SEO is one of the popular WordPress plugins that lets you optimize your website with necessary keywords to improve search engine ranking. So if you want to improve your website’s position in search results, then I would strongly recommend Yoast SEO plugin. But for some reason, you might not want the plugin to leave comments in the page source. If you are someone like me who wants to remove those comments from the page sources, then here’s how you can do that.

Step 1: Copy the below code snippet.

For Yoast SEO plugin version less than 14.1, add the below code in functions.php

if (defined('WPSEO_VERSION')) {
 add_action('wp_head',function() { ob_start(function($o) {
return preg_replace('/\n?<.*?yoast seo plugin.*?>/mi','',$o);
 }); },~PHP_INT_MAX);
}

Step 3: Paste the code to the end of the file.

Step 4: Save and exit.

Step 5: Load your WordPress site and right-click to view the page source. That’s it, the SEO comments are removed from the page source.
