Add to cart is the action a shopper takes when they select a product on an ecommerce store and save it to their virtual shopping cart before completing a purchase. It is a key moment in the buying journey, the digital equivalent of picking up an item in a physical store and holding onto it while you continue browsing. The product is not purchased yet. It is simply stored, giving the shopper time to compare, add more items, and decide when they are ready to check out.
Clicking add to cart signals strong purchase intent. The shopper has moved past passive browsing and is actively considering buying. For merchants, tracking this behaviour helps measure product interest, forecast demand, and identify where the buying journey breaks down.
When a shopper adds to cart but does not complete the purchase, it becomes an abandoned cart, one of the most recoverable revenue leaks in ecommerce. This is also why retargeting works so well at this stage, because you already know exactly what the shopper wanted.
When a shopper clicks the add to cart button, the selected product along with any chosen options like size, quantity, or colour is saved to a virtual cart stored in their browser session or account. From there, they can continue shopping or go straight to checkout.
For subscription products, the cart experience often includes additional selections such as billing frequency, plan type, or free trial options before the shopper proceeds. This makes the add to cart step even more significant for subscription merchants because the choices made at this point directly affect the subscriber’s billing setup.
They serve different purposes. Add to cart lets the shopper save a product and keep browsing, collecting multiple items before paying in a single checkout. Buy now skips the cart entirely and takes the shopper straight to checkout for an immediate, single-item purchase. For merchants selling subscriptions, add to cart is almost always the better flow because it gives the shopper time to select their plan and billing preferences without feeling rushed.
The add to cart rate measures the percentage of visitors who click add to cart compared to total site visitors. A healthy add to cart rate typically ranges between 5% and 15%, though this varies by industry and product type.
A strong rate means your product pages are building enough confidence and interest to push shoppers toward action. A low rate usually points to friction on the product page, unclear descriptions, weak images, confusing pricing, or a button that does not stand out.
Improving your add to cart rate is one of the first levers in any conversion rate optimisation strategy because it sits right at the point where browsing turns into buying intent.
A shopper lands on a Shopify store selling a monthly skincare subscription. They read through the product page, choose their preferred plan, and click add to cart. From there they review their selection and head to checkout. That single click moved them from interest to active purchase intent and started the billing setup for a recurring subscription.
For subscription products, your add to cart button is doing more than collecting a one-time purchase. It is the entry point to a recurring revenue relationship. Make sure the path from product page to cart is frictionless, with clear plan options, visible billing frequency, and a button that is easy to find on every device. The easier you make that first click, the better your subscriber conversion rate will be.
