So I have read over the Product List Attribution, and can not really understand why my addToCart, checkout and purchase data is not coming through in the product list performance reports in GA.
Product Attribution
In Enhanced Ecommerce, the Product List Performance report includes useful Product Attribution data. The report includes a "last action" attribute which gives product level credit to the last Product List (i.e. add to cart, checkout, or purchase) that the user interacted with prior to the conversion event.
Product Attribution data helps you understand which Product Lists are driving conversions and allows you to optimize your merchandising efforts and drive sales. For example, you can now understand whether users are purchasing a product as a result of clicking on a merchandising block, category page, or on the search results page.
To get started with Product Attribution, make sure to specify the list attribute on your ecommerce action data. This list field will be used to then attribute Product Adds To Cart, Product Checkouts, Unique Purchases, and Product Revenue in the Product List Performance report accordingly
I'm implementing this in GTM. I'm trying to track each one of my category pages performance however, I would like to track the Product List through the whole checkout process "Product Adds To Cart, Product Checkouts, Unique Purchases, and Product Revenue"
Does this mean I will have to assign the product list value for each product on checkout event & purchase events? if so how do you recommend I do this.
For example if a person views a product on category A, clicks a product and then continues through the addToCart checkout and purchase do I need to record that it was product list A that lead to the addToCart, checkout and purchase at each step???
