#32: Do you have relevant interaction when users add products to cart?
There are different ecommerce stores with thousands of products or with one or only a few products.

There are stores that are only acquiring traffic directly to specific product page and stores that have mostly organic or direct traffic that comes to homepage and then browse the store. Hence shopping funnel and desired experience can be different in such cases.
In the same way, what happens after clicking the ATC button may differ.

A store with thousands of products can show just a sliding window or a popup to notify about added product to cart and then motivate users to continue shopping. While a store with one product may not have an Add to Cart button at all, and instead show the Buy Now button and send users directly to the Checkout process.

If users usually purchase just one product on your store, it's better to redirect them directly to cart page or even to checkout pages. That way you're taking them one step closer to making a payment. It's more streamlined purchasing funnel.

If users usually shop many products in your store or you have many related items (and you want to cross-sell them), it's better to show sliding cart window or modal. It tends to make it easier for users to continue shopping. But if you decide to send users to cart page, you can consider adding there promotion of related or completentary products.

Example of purchasing flow on Asos:
I guess they expect that users will continue to shop after adding product to cart. That's why they just show sliding window and don't try to streamline purchasing process.
