How to clean headers in WordPress?
WordPress has by default inserts a lot of unnecessary code into the header of the HTML source code, sometimes we don’t need to use it.
I will talk about the components that should be removed to clean the header
These include:
- Really simple discovery link (rsd_link)
- WordPress version (wp_generator) : wordpress version <meta name =” generator ” content =” WordPress 5.7.2 ” />
- RSS feed links (feed_links and feed_links_extra)
- Link to index page (index_rel_link)
- wlwmanifest.xml (wlwmanifest_link)
- Random post link (start_post_rel_link)
- Parent post link (parent_post_rel_link)
- Next and previous post links (adjacent_posts_rel_link)
- WP shortlink (wp_shortlink)
To remove all the above code in the WordPress header, you just need to add the following code in the functions.php file of the theme or child theme you are using:
remove_action('wp_head', 'rsd_link'); // remove really simple discovery link
remove_action('wp_head', 'wp_generator'); // remove wordpress version
remove_action('wp_head', 'feed_links', 2); // remove rss feed links (make sure you add them in yourself if youre using feedblitz or an rss service)
remove_action('wp_head', 'feed_links_extra', 3); // removes all extra rss feed links
remove_action('wp_head', 'index_rel_link'); // remove link to index page
remove_action('wp_head', 'wlwmanifest_link'); // remove wlwmanifest.xml (needed to support windows live writer)
remove_action('wp_head', 'start_post_rel_link', 10, 0); // remove random post link
remove_action('wp_head', 'parent_post_rel_link', 10, 0); // remove parent post link
remove_action('wp_head', 'adjacent_posts_rel_link', 10, 0); // remove the next and previous post links
remove_action('wp_head', 'adjacent_posts_rel_link_wp_head', 10, 0 );
remove_action( 'wp_head', 'print_emoji_detection_script', 7 );
remove_action( 'wp_print_styles', 'print_emoji_styles' );
remove_action('wp_head', 'wp_shortlink_wp_head', 10, 0); // Remove shortlink<div>
