Keep Filtered and Sorted Shop Pages Out of Search Engines
Adds noindex to shop pages that have sorting, price or attribute filters in the URL, so search engines index your real category pages instead of thousands of variations.
Opens WPIDE on
Code
add_filter( 'wp_robots', function ( $robots ) {
if ( ! function_exists( 'is_woocommerce' ) || ! ( is_shop() || is_product_taxonomy() ) ) {
return $robots;
}
foreach ( array_keys( $_GET ) as $key ) { // phpcs:ignore WordPress.Security.NonceVerification
if ( in_array( $key, array( 'orderby', 'min_price', 'max_price', 'rating_filter', 'query_type' ), true ) || 0 === strpos( (string) $key, 'filter_' ) ) {
$robots['noindex'] = true;
$robots['follow'] = true;
unset( $robots['index'] );
break;
}
}
return $robots;
} );Notes
Links on those pages are still followed, and normal shop, category and paginated pages are not affected.
