WordPress: how to remove the ‘link rel=shortlink’ tag from your site


in ,

By default, WordPress adds <link rel="shortlink"> meta tag to the <head> of a website and uses the short url like https://mixable.blog/?p=4803 for this. When you already use nice slugs as permalink structure, such a tag is not necessary, because you already have unique urls.

To remove the shortlink tag, you can use an additional plugin or simply add some code to your themes functions.php:

add_filter('after_setup_theme', 'remove_redundant_shortlink');

function remove_redundant_shortlink() {
    // Remove HTML meta tag
    // <link rel='shortlink' href='http://mixable.blog/?p=12345' />
    remove_action('wp_head', 'wp_shortlink_wp_head', 10);

    // Remove HTTP header
    // Link: <https://mixable.blog/?p=12345>; rel=shortlink
    remove_action( 'template_redirect', 'wp_shortlink_header', 11);

This code will also remove a http header from each response.
