If you are still thinking about why to track add-to-cart event then,

This blog might feel a little advanced for you. However, let’s quickly wrap up why tracking add to cart event for your WooCommerce store is essential. 

Add to cart event is one of those crucial events that gives you a better analysis of how the users behave on your WooCommerce store. It helps you understand the cart-to-purchase ratio, total website visitors to add-to-cart, and more!

Not just that, with some advanced audience segmentation, you can segment add-to-cart event audiences in the last 45 days and retarget them across to increase the overall conversion rates and ad campaign performance. 

So, in short, add-to-cart event tracking is crucial because it helps:

  • Run targeted and personalized ad campaigns
  • Increase ad campaign performance with a better ROAS (Return on ad spend)

Now that you know how important it is, let’s see

Common issues with tracking add-to-cart event effectively

Most marketers think they have setup conversion tracking in Google Ads and are tracking the add-to-cart event correctly. 

However, they often realize that the numbers do not add up correctly, causing huge discrepancies in the data (GA4, and Google Ads, show different numbers). It is because you are tracking them the wrong way. There are many scenarios why this discrepancy pops up. Some of them include redirection, buttons not tracked correctly, Buy Now button beside the add-to-cart button, and more. 

The default plugins available track add to cart event on the browser side and lack customization flexibility. Although these plugins have a direct one-click data synchronization with Google Ads, fail to collect the user data effectively without any signal loss. 

The right way to track add-to-cart event for your WooCommerce store

To stay ahead of the game, WooCommerce marketers have to adapt to the advanced tools that help collect data effectively, play around with it, and sync with Google Ads without any signal loss. 

One of the advanced tools that helps you track all the events including add to cart event effectively is the CustomerLabs WooCommerce conversion tracking plugin. It also feeds Google Ads with the right audience signals. It offers a robust conversion tracking feature that powers your Google Ad campaigns with the right audience signals.

Note: CustomerLabs WooCommerce conversion tracking plugin also helps you track events on any website built on WordPress.

Now, let’s say your ad campaign optimized for purchase event does not work as expected, due to insufficient purchase data. In this scenario, you must optimize your ad campaign for the second most valuable action – checkout made/add payment info.
