Debugging Google Analytics 4 for Google Tag Manager

Even the most advanced Google Tag Manager users often run into issues while setting up new tags. Frustrated by the process we often ask ourselves, why doesn’t my tag fire, what data is sending to Google Analytics and why didn’t this trigger work?

One of the most overlooked, yet important steps while working with GTM is its preview and debugging mode. Google Tag Manager’s preview mode allows you to preview your container code as if the current container draft was deployed so that you can test your configuration before it is published.

For general debugging information see how to debug Google Tag Manager

How to debug productClick event not triggering

Unlike other Enhanced Ecommerce extensions that add hundreds of lines of JavaScript to your site, our extension was designed to minimize the amount of code injected in your site. Our extension was design to use Magento HTML and CSS classname to function correctly. In rear situation third party themes, extensions or developers my change the default Magento structure which cause our extension to not fire all events. Fixing this is as simple as remapping your site HTML structure in our extension.

In Chrome or any other browser, go to your Elements tabs and find the item collection elements.

Class Name | Selector

• #1 Should map to the outer wrapper or parent element of your items collection
• #2 Should map to the individual product element parent container
• #3 Should map to each hyperlink that when click on take you to the product detail page

Container Class Name | Selector

• #4 Should map to the individual product element parent container. eg li or div

You can quickly test your selector you run the code below in your browser’s console.

//should return each product link
jQuery('.products-grid .product-item a[class*="product-item-"]')

//should return the parent container for each item
jQuery('.products-grid .product-item')
