What is ATC?
ATC means add to cart: an event indicating that a shopper placed an item in a cart.

A practical example
If 60 of 1,000 product-page visitors add an item, an ATC-per-visitor rate is 6%, assuming unique people and a consistent counting method.
How to use it
An add-to-cart is a step toward a purchase, not a sale. Check shipping costs, delivery dates, and checkout usability when carts rise without orders.
Put it in a creative brief
Write down the event, asset, or workflow you mean by ATC before sharing a brief or report. For campaign measurements, keep the source and reporting window with the number. For creative work, attach an example so the team can assess the same thing.
