Remove WordPress headers and goals

Last Revised: October 2, 2021

Like most content management systems, WordPress clearly identifies itself and offers certain services that we will later use (or not). And usually this fact involves small elements that let you see information and decrease security.

This is why it is highly recommended to hide certain headers that appear in the <head> (or other elements, such as feeds) of the page. There are a couple of dozens of codes that can be deleted if we do not want to have certain elements working.

Disable headers

 * Remove feeds and wordpress-specific content that is generated on the wp_head hook.
 * @link
    function () {

    // Remove the Really Simple Discovery service link
    remove_action( 'wp_head', 'rsd_link' );

    // Remove the link to the Windows Live Writer manifest
    remove_action( 'wp_head', 'wlwmanifest_link' );

    // Remove the general feeds
    remove_action( 'wp_head', 'feed_links', 2 );

    // Remove the extra feeds, such as category feeds
    remove_action( 'wp_head', 'feed_links_extra', 3 );

    // Remove the displayed XHTML generator
    remove_action( 'wp_head', 'wp_generator' );

    // Remove the REST API link tag
    remove_action( 'wp_head', 'rest_output_link_wp_head', 10 );

    // Remove oEmbed discovery links.
    remove_action( 'wp_head', 'wp_oembed_add_discovery_links', 10 );

    // Remove rel next/prev links
    remove_action( 'wp_head', 'adjacent_posts_rel_link', 10, 0 );

    // Remove prefetch url
    remove_action( 'wp_head', 'wp_resource_hints', 2 );


I recommend that if you want to know what each function is, analyze it with the WordPress Codex documentation. The actions commented on are because they are of old versions, in principle already obsolete.
