    • Product ID [Required]
    • Page Type [Optional]
    • Total Value [Optional]

  • You are free to pass other values in optional attributes as per your needs.
  • In Analytics, go to Property > Custom Definition > Custom Dimensions.
  • Create 3 Hit level dimensions, (can name anything)
    • ecomm_prodid

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.

  • Also, an error might arise due to code not on all pages.

  1. Hi there Ritwik,

    This is an excellent guide and extremely helpful. I wonder if you could really breakdown steps 3 and 4 more as those are quite confusing. Also, I noticed you started using ecommerce business type instead of the custom business type which you used in part 1. It would be great if you could continue using the custom one.

    Thanks very much for this.

    1. Hi Brian,

      The naming doesn’t matter. I can even name it as ‘ mysite_id ‘ , ‘mysite_page’ , ‘mysite_val’. There are 2 important steps.
      1.) First is the STEP – 2, to assign mysite_id to Product ID & so on……
      2.) Second important step is the values filled in spreadsheet. The ids column in spreadsheet/excel should match the values in Product ID variable (step 2).

      Maybe I’ll create live setup video soon.

      Thanks,
