Product List Performance
A product list is a page where multiple products are listed such as a category page or search results. You can see views, clicks, add to carts and checkouts as well as unique purchases, revenue and CTR (click-through ratio).

Product performance tracks individual products by name and/or sku. You can see the metrics for each product: revenue, quantity, averages, cart-to-detail, buy-to-detail ratios. If you have a high cart-to-detail but low buy-to-detail ratio you’ll know you need to optimize the checkout process.
