This is a common issue with Google Tag Manager when tracking outbound links. When the outbound link has target=”_blank” attribute GTM doesn’t trigger the event tag to record the outbound click. An easy way to fix this is to remove the target=”_blank” attribute from your links, that said if you have hundreds of posts with external links that already open in a new tab this could take forever.

We came up with a quick workaround that allows you to still open external links in a new tab but you don’t have to set ‘open in a new tab’ in WordPress.

This method uses a short script to remove all target=”_blank” attributes from external links and we will create a tag in GTM to then add the attribute again using GTM.

Remove target=”_blank” Attributes

You can do this by adding a snippet to your site footer, we do this by adding the following function to your child theme functions.php.

function external_link_attribute() {
  	.forEach(link => link.removeAttribute('target'));
add_action( 'wp_footer', 'external_link_attribute', 20 );

This function will simply look for all links that contain target=”_blank” and remove the attribute.

Create a Tag in GTM to open outbound links in a new tab

This step requires creating a new tag in GTM that will then open outbound links in a new tab. This method follows the guide created

This involves adding the following script to a new tag that will open all external links in a new tab. This is done from GTM so it will trigger after the outbound event click.

Go into GTM and create a new tag named HTML – LinkOpener – All Pages. Set the Tag Type to Custom HTML. Paste the code below into the source code window. Set the Firing Trigger to All Pages.

var links = document.links;
for (var i = 0, linksLength = links.length; i < linksLength; i++) {
  if (links[i].hostname != window.location.hostname && links[i].protocol != 'tel:' && links[i].protocol != 'mailto:' ) {
    links[i].target = '_blank';
    links[i].rel = 'noopener noreferrer';

Your tag should look like this.
