“Does Yoast SEO Work With Custom Post Types?
Yoast SEO works with public custom post types which is the default option when creating a custom post type.
If the custom post type is defined with no public statement or ‘public’ => true, then Yoast SEO functionality will also be available.
If the custom post type is defined with ‘public’ => false, the Yoast SEO functionality will not be available.”
