Exclude category and tag archive pages from being indexed

Hello Nirr! The breadcrumbs you see in search results are derived from schema markup.
This filter should help:

add_filter( 'slim_seo_breadcrumbs_links', function( $links ) {
    if ( is_singular( 'post' ) ) {
        unset( $links[1] );
    }
    return $links;
} );

To ensure that the category is no longer visible in the schema markup, check the post page here:
https://search.google.com/test/rich-results

Thanks for the reply, Dmitry!

I tried that snippit, and unfortunately it didn’t work for me.

However, I created the below snippet with the help of ChatGPT and it did work!

add_filter( 'slim_seo_breadcrumbs_links', function( $links ) {
    if ( is_singular() ) { // For singular posts, pages, or custom post types
        foreach ( $links as $index => $link ) {
            if ( strpos( $link['url'], '/category/' ) !== false ) {
                unset( $links[$index] );
            }
        }
        $links = array_values( $links ); // Reindex the array
    }
    return $links;
});

Or this?

add_filter( 'slim_seo_breadcrumbs_links', function( $links ) {
    // Filter the links to remove any that contain '/category/'
    $links = array_filter( $links, function( $link ) {
        return strpos( $link['url'], '/category/' ) === false;
    });

    // Reindex the array after filtering
    $links = array_values( $links );

    return $links;
});

I think 2nd code is more concise and efficient.

Which do you recommend @anh Tran? Can we use them safely?
