Notify when an item has been added to cart

When a shopper adds an item to their cart don’t make them guess whether the item has been added or not, provide a prominent confirmation message. You can either provide the confirmation message on the same page or redirect them to the cart page. When you keep the shopper on the same page, provide product recommendations along with the confirmation message so that they can buy more.

If most of your shoppers buy only one item at a time or if you sell high priced items, then redirect them to the cart/confirmation page after they add an item to cart.
