  • In Analytics, go to Property > Custom Definition > Custom Dimensions.

Step 3:

DataLayer Placement

  • In Google Tag Manager, we will start with dataLayer placement method.
  • Use this method if you have access to the backend.
  • You can place the code on different pages such as
    • product_listing_pages
    • search_results_pages
    • product_pages
    • coupon_code_pages
    • & so on
  • Here is the code you can place on search results page. You should dynamically replace
    • ecomm_totalvalue = total value of products on the pages
    • ecomm_prodid = array of product ids on the page.

 

  • On Product Pages

  • and so on

 

One HTML Custom Code

  • Create Custom HTML Tag in GTM & paste below code.
  • Trigger on All Pages.
  • Fire Google Analytics event tag with different custom events.
  • You can place a single code on all pages but add the page conditions.

 

Custom JS 

  • You can also trigger Custom JS on events like Add To Cart, Remove from Cart, Coupon Code Clicked, etc

 

Step  4:

  • Create custom dataLayer variables in GTM. (ecomm_prodid, ecomm_pagetype, ecomm_totalvalue)
  • Pass it with the analytics event tag or pageview tag in custom dimensions.
  • Verify the Index is proper with the metrics defined in Step #2.

  • You’ll see an error for 2-3 days until the data gets populated via analytics. So ignore it.
  • Also, an error might arise due to code not on all pages.
