Remove junk from the WordPress header

If you ever view the source of your WordPress blog, you’ll notice that WordPress adds a bunch of unnecessary junk into the header.

It includes:

• A Really Simply Discovery link so other services - Flickr, for example - can easily publish to your blog.
• A Windows Live Writer link, which is only useful if you use Windows Live Writer.
• The version of WordPress you’re using, which matters to no one.
• Links to the next and previous posts, as well as a random older post, all uselessly hidden in the header.

Removing this junk is as simple as adding a few lines of code to your functions.php file. Here’s the code, courtesy of Theme Lab…

remove_action('wp_head', 'rsd_link'); // Removes the Really Simple Discovery link
remove_action('wp_head', 'wlwmanifest_link'); // Removes the Windows Live Writer link
remove_action('wp_head', 'wp_generator'); // Removes the WordPress version
remove_action('wp_head', 'start_post_rel_link'); // Removes the random post link
remove_action('wp_head', 'index_rel_link'); // Removes the index page link
remove_action('wp_head', 'adjacent_posts_rel_link'); // Removes the next and previous post links
