In the fast-paced world of online retail, understanding customer behavior is crucial for success. Effective e-commerce tracking can enable you to gather insights into user interactions, optimize your sales funnel, and boost your conversion rates.

Why Should Use Google Tag Manager for E-commerce Tracking?

Google Tag Manager simplifies the implementation of tracking codes on your website, allowing you to manage tags without need to alter your website’s code directly. This flexibility makes it easier to track e-commerce events such as product views, add-to-cart actions, and completed transactions.

Step 1: Set Up Google Tag Manager

  1. Create Your GTM Account: If you don’t have an account yet, go to the Google Tag Manager website and create one.

Install GTM: After create up your account, you’ll receive a GTM container code. Add this code to your website’s header and body as per the instructions provided by GTM

Step 2: Enable E-commerce Tracking in Google Analytics

Before you can track e-commerce events, ensure that you have Google Analytics set up:

  1. Link GTM to Google Analytics: Go to your Google Analytics account and find the property you want to track.
  2. Enable E-commerce Tracking: Navigate to Admin > View Settings and enable E-commerce.

Step 3: Create E-commerce Tags in GTM

To track key e-commerce interactions, you’ll need to create specific tags for events:

  • Create a New Tag:
    • Tag Type: Google Analytics: Universal Analytics
    • Track Type: Event
    • Fill in the Category, Action, and Label based on your tracking strategy.

2. Track Add to Cart Actions

This monitors when customers add products to their cart.

  • Create Another Tag using the same process as above, but customize it for the Add to Cart event.

3. Track Completed Transactions

Capture data for successful purchases.

  • Create a Tag for Purchases:
    • Set Track Type to Transaction.

Step 4: Set Up Triggers for Your Tags

  • Page View Trigger: For product impressions.
  • Custom Event Trigger: For Add to Cart and Purchase events.

                                                        ‘ecommerce’: {

                                                        ‘currencyCode’: ‘USD’,

                                                         ‘add’: {

                                                         ‘products’: [{

                                                         ‘name’: ‘Product Name’,

                                                         ‘id’: ‘Product ID’,

                                                          ‘price’: ‘Product Price’,

                                                          ‘category’: ‘Product Category’,

                                                           ‘quantity’: 1

                                                             }]

                                                      }

                                               }

                                 });

Step 6: Test Your Setup
