Once users add an item to their cart, let them know about it by implementing a cart item count badge next to the shopping cart icon. According to the NN Group, a clear indication, such as a visible badge, of the number of added items in the cart gives users a sense of control. As a result, they feel more confident about continuing to shop or completing their checkout. Make sure the cart badge stands out — the color red is a great choice for adding a strong accent.^[1]
