How to add an Ad Tag to <head> section in WordPress

Paste your EZmob code into the <head> section of your WordPress site using a plugin, a child theme or the wp_head hook. Note: wordpress.com addresses can't be validated. Only a site on a custom domain can be validated and receive premium demand.

Copy your ad code

1. In the EZmob dashboard, open Sites & Placements → Your Placements.
2. Click the code icon (View Script) on the placement.
3. Click Copy Script.

Option 1: Use a plugin (easiest)

1. Install any plugin that inserts code into the site header.
2. Paste the code into the plugin's header (<head>) field for all pages.
3. Save.

Option 2: Edit a child theme

1. Open your child theme's header.php. Don't edit the parent theme, or updates will remove your change.
2. Paste the code just above </head>.
3. Save the file.

Option 3: Use the wp_head hook

Add this to the end of your theme's functions.php, replacing the comment with your code:

function ezmob_insert_header() {
    ?>
    <!-- Paste your EZmob code here -->
    <?php
}
add_action( 'wp_head', 'ezmob_insert_header' );

Use any of these options to add your site's Validation Code too, then click Validate in EZmob.

Header Bidding banner

The Header Bidding code ends with <div id="container1"></div>, which marks where the banner shows.

1. Add the code without that <div> to <head>, as described above.
2. In WordPress, go to Appearance → Widgets.
3. Add a Custom HTML widget to your sidebar, paste <div id="container1"></div> and save.
