Hi all,

I have tried many things to optimise a website that having MySQL performance issue due to apparently Yoast

this is website have a sitemap of +1 300 pages with 1000urls each due to important bbpress forum

so I tried to exclude them and it work

but I would like something more advance like :
Keep only the 250 last URL of each type
or Kepp only the URL of the past week

The first function working but not the other one (I sued it once each not all function in same time)

/* Exclude Multiple Content Types From Yoast SEO Sitemap */
add_filter( 'wpseo_sitemap_exclude_post_type', 'sitemap_exclude_post_type', 10, 2 );

function sitemap_exclude_post_type( $value, $post_type ) {

        if ( strtotime( $post->post_date_gmt ) < strtotime( '-1 week' ) ) {

Do you have any ideas ?

I'm trying to optimise this SQL query actually :

SELECT l.ID, post_title, post_content, post_name, post_parent, post_author, post_status, post_modified_gmt, post_date, post_date_gmt
                        FROM (
                                SELECT WP_posts.ID
                                FROM WP_posts

                        WHERE WP_posts.post_status IN ('publish')
                                AND WP_posts.post_type = 'topic'
                                AND WP_posts.post_password = ''
                                AND WP_posts.post_date != '0000-00-00 00:00:00'

                                ORDER BY WP_posts.post_modified ASC LIMIT 100 OFFSET 101500
                        )
                        o JOIN WP_posts l ON l.ID = o.ID;

The first example, file-yoast_seo_sitemap_add_custom_type-php, is not complete. Function is not properly closed. Also, we don't know what create_TYPE_sitemap callable is and does, how to create our own implementation.

@djboris88 The plugin automatically detects most custom post types (CPT), so you'd only need this in some instances. You can check under Admin > Yoast SEO > Settings > Content types to see if your CPT was detected automatically.

The code requires that you replace TYPE with your CPT. For example, if your CPT is called recipe, the register sitemap line would change as shown here.

$wpseo_sitemaps->register_sitemap( 'recipe', 'create_recipe_sitemap' );
