product list performance report
I have made use of Enhanced Analytics and have access to the Product list performance report.
I've noticed that for some products, it records the value for checkout and revenue but not for add to cart.
And for some products it records add to cart activity but no record of this been checked out or generating revenue.
All products have had orders placed.
Re: product list performance report
this can happen if the action have not been performed inside a session but in multiple sessions so this kind of information is not stitched cross session.
For instance if the shop in question allows buying a product without actually having an add to cart action present OR if a person adds to cart and in a subsequent session buys from a permanent cart (if this feature exists).
Hope it helps!
