The first code works!

Thank you very much!

It almost works!

If I put that code with “noindex”, without the double-quotes:

add_action( 'pre_get_posts', function( \WP_Query $query ) {
	if( ! is_admin() && $query->get( 'crp_query' ) ) {
		$meta_query = [
			'relation' => 'OR',
			[
				'key' =>  'rank_math_robots',
				'value' => 'noindex',
				'compare' => 'LIKE',
			],
			[
				'key' =>  'rank_math_robots',
				'value' => '',
				'compare' => 'NOT EXISTS',
			]
		];

		$query->set( 'meta_query', $meta_query );
	}

	return $query;
});

Only posts with noindex appear.

But, if I put “index”, it does nothing.

Thank you very much

Hello Ajay,

I received a reply from RankMath:

“Rank Math uses these values in the database for the index/noindex (wp_postmeta table):

meta_key: rank_math_robots
meta_value: a:1:{i:0;s:5:"index";} or a:1:{i:0;s:5:"noindex";}

So I guess if I use the following code in the functions.php, it should works:

<?php

add_action( 'pre_get_posts', function( \WP_Query $query ) {
	if( ! is_admin() && $query->get( 'crp_query' ) ) {
		$meta_query = [
			'relation' => 'OR',
			[
				'key' =>  'rank_math_robots',
				'value' => '1',
				'compare' => '!=',
			],
			[
				'key' =>  'rank_math_robots',
				'value' => '',
				'compare' => 'NOT EXISTS',
			]
		];

		$query->set( 'meta_query', $meta_query );
	}

	return $query;
});

Am I right?

Thank you very much

Thank you very much for you reply

I have been researching and RankMath works with filters. For example, to set noindex for product filters, it uses:

add_filter( 'rank_math/frontend/robots', function( $robots ) {
if (is_paged() || is_product_category() || isset($_GET['filters'])) {
	$robots['index'] = 'noindex';
	return $robots;
}
return $robots;
});

How could I adapt it?

Thank you very much for your support!
