Google Tag Manager

Website analytics provide insights and data that you can use to create a better user experience for your customers. Understanding customer behavior is the key to optimizing a website for key conversion metrics.

The Good Store comes with an out-of-the-box Google Tag Manager integration that allows your website to communicate with your Google Tag Manager account. Google Tag Manager allows you to configure and publish tags to your e-commerce website through its web-based user interface instead of having to manually add tags to your website code. Through tags, you can track and analyze how customers interact on your website.

Google Tag Manager supports Google products, like Google Ads and Google Analytics, and third-party vendors. Google Tag Manager also supports custom tags.

Prerequisites

A Google Analytics 4 account.
A Google Tag Manager account and container for your website.

To track events from your website, follow these steps:

For the NEXT_PUBLIC_GA_TRACKING_ID variable, set your Google Tag Manager container ID as the value. If you are working locally, you are set.
On production, set your Google Tag Manager container ID as the value of the environment variable on Netlify or any other provider.
