Leave Noindexed Content Out of Site Search
Hides posts and pages that you set to noindex in Yoast SEO or Rank Math from your own site search, such as thank-you pages and thin landing pages.
Opens WPIDE on
Code
add_filter( 'posts_where', function ( $where, $query ) {
global $wpdb;
if ( is_admin() || ! $query->is_main_query() || ! $query->is_search() ) {
return $where;
}
// Yoast SEO: "Allow search engines to show this content" set to No.
if ( defined( 'WPSEO_VERSION' ) ) {
$where .= " AND NOT EXISTS ( SELECT 1 FROM {$wpdb->postmeta} wpide_ny WHERE wpide_ny.post_id = {$wpdb->posts}.ID AND wpide_ny.meta_key = '_yoast_wpseo_meta-robots-noindex' AND wpide_ny.meta_value = '1' )";
}
// Rank Math: "No Index" ticked in the robots meta.
if ( defined( 'RANK_MATH_VERSION' ) ) {
$where .= " AND NOT EXISTS ( SELECT 1 FROM {$wpdb->postmeta} wpide_nr WHERE wpide_nr.post_id = {$wpdb->posts}.ID AND wpide_nr.meta_key = 'rank_math_robots' AND wpide_nr.meta_value LIKE '%noindex%' )";
}
return $where;
}, 10, 2 );Notes
Uses each post's own robots setting; content type-wide noindex settings in the SEO plugin are not checked.
