If you have a paypal merchant account, you are most likely selling products or services using a paypal buy button or a shopping cart. This insight will tell you which of your products are bringing you the most sales.The products that generate the most revenue are ranked and listed.
If a certain product or SKU is not generating any sales, you can focus your resources on either improving the visibility of the product, create more marketing around it or focus on the products that are generating more sales and make improvements. Try boosting sales on certain products by sending an email marketing promotion bundling products that make sense together. You might find that giving a discount on a bundle will increase sales for those products.
Note: You should have a paypal merchant account to see meaningful data in this insight. If you have connected a personal paypal account, you may not see any relevant data here.
