How to exclude the main taxonomy page from sitemap ?

Hello @rstrah,

Thank you for contacting Rank Math support.

Please use the following filter to exclude the URLs from the sitemap:

add_filter( 'rank_math/sitemap/entry', function( $url, $type, $object ){
$excluded_urls = [
'https://site.com/blog/',
'https://site.com/case_studies/',
'https://site.com/services/',
'https://site.com/solutions/'
];
$post_url = get_permalink($object->ID);
if ($type === 'post') {
if (in_array($post_url, $excluded_urls)) {
return '';
}
}
return $url;
}, 10, 3 );

Please make sure to flush the Sitemap cache by following this video screencast after adding the filter: https://i.rankmath.com/pipRDp
