Add to cart

Add to cart (ATC)

E-commerce

The action of putting a product in an online shopping cart, and the button that does it. Add-to-cart rate measures how many visitors take that step.

What is Add to cart?

Adding to cart is the first strong sign that a shopper intends to buy. It sits in the middle of the conversion funnel, after viewing a product and before checkout. Add-to-cart rate is usually measured as the share of sessions, or of product page views, that include at least one add to cart. Be clear which one you use, because the numbers differ a lot. What lowers it: - A button that is hard to find, especially on phones. - Missing information: size, ingredients, shipping cost or delivery time. - Too many choices with no clear default. - Slow pages and broken option pickers. - Prices that look different from the ad that brought the shopper in. What raises it: - A sticky button on mobile that stays visible while scrolling. - Reviews and photos near the price. - A clear subscribe option with the savings shown. - Bundles and quantity breaks that make a bigger order the obvious pick. Add to cart isn't a sale. Many carts are abandoned before checkout. Track cart abandonment and checkout completion next to add-to-cart rate, or you may celebrate carts that never turn into orders. Add-to-cart links skip a step entirely. On Shopify you can build a link that drops a product, and even a subscription plan, straight into the cart, which is handy in emails and texts.

Formula

Add-to-cart rate = Sessions with an add to cart ÷ Total sessions × 100

Example

A store has 20,000 sessions in a week, and 1,400 of them add something to the cart. Its add-to-cart rate is 7%. After making the button sticky on mobile, it rises to 8.2% the next week.

Why Add to cart Matters

It's the clearest early signal of whether your product pages persuade, long before you see the final sales numbers.
