How To Noindex Only From Googlebot, and Still Normal To Other Robots?

Hello @ichanx,

Thank you for contacting the support.

You can add the following filter to prevent GoogleBot from crawling and indexing your site:

add_action( 'wp_head', function() {
	   ?>
	   <meta name="googlebot" content="noindex, nofollow">
	   <?php
   } );

You can follow this guide to add the code:

Hope that helps.

That filter that you wrote will block googlebot from the whole site. I only want to implement it to some of my post page.

Hello @ichanx,

You can add a condition in the filter that applies the tag only to the required posts.

Here’s an example code:

add_action( 'wp_head', function() {
	$post_ids = [1044, 1033];    // Add required post IDs 	
	if(in_array(get_the_ID(), $post_ids)):
      ?> 
      <meta name="googlebot" content="noindex, nofollow"> 	   
      <?php 	
    endif; 
} );

You can replace the IDs in $post_ids variable with the IDs of posts where the tag is to be applied.

Here’s how you can get the post ID:
