Noindex all posts for custom post types

Hi @richardu,

Excluding CPT from sitemap doesn’t tell search engines to not index them. It’s simply doesn’t send CPT’s URL to search engines. If search engines can discover posts in another way (by crawling your site), then they still can index them.

To tell search engines to not index these posts, it’s better to use the robots tag. This snippet set robots tag to noindex for a CPT:

add_filter( 'slim_seo_robots_index', function( $value ) {
    if ( is_singular( 'your_cpt' ) ) {
        return false;
    }
    return $value;
} );

Thanks. That’s exactly what I needed. Perhaps this should be in your documentation.

Cheers, Richard

Thank you, Richard. I’ve updated the docs.
