Lightweight WordPress Meta Tag Description Plugin in 5 Minutes

No child themes. No heavy plugins. No file hacks that vanish on updates. Just your own lightweight WordPress plugin to add a global meta description tag.

1. Connect to your WordPress hosting server via FTP.
2. Create a new folder:
   wp-content/plugins/mymetadescription
3. Inside that folder, create a file:
   mymetadescription.php
   Add the code provided below into this file.
4. Activate your plugin in the WordPress Admin Dashboard.
   

<?php
/*
Plugin Name: MyMetaDescription
Description: Adds a global meta description to the header.
Version: 1.0

*/

function add_meta_description() {
    echo '<meta name="description" content="Enter your blog description here." />' . "\n";
}

add_action('wp_head', 'add_meta_description');

To verify it works, reload a page on your blog, view the page source, and search for:

<meta name="description"
