Does Yoast SEO Work With Custom Post Types?
As of Yoast SEO 20.0, the settings interface inside our plugins has received a major overhaul. Please update to the latest version of Yoast SEO if your plugin does not look like the screenshots you encounter in our Help center.
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.
