Sessions adding an item to cart ÷ total sessions.
"Our add-to-cart rate is 9% but only a third reach checkout."

What the metric captures

Add-to-cart rate is the share of visits where someone puts a product in the cart. It is the first behaviour that separates a browser from a potential buyer.

Because it sits early in the funnel, it reacts fast to merchandising, price clarity, product imagery, and how obvious the add-to-cart button is. A weak rate usually points to the product or detail page, not the checkout.

Where it sits in the chain

Add-to-cart rate, checkout rate, and purchase rate are a chain. A healthy add-to-cart rate with poor checkout completion tells you the problem is downstream — shipping cost, account walls, payment friction.

A low add-to-cart rate itself points upstream — traffic quality, product-market fit on the page, pricing, or a button buried below the fold. Diagnosing which link is weak is the whole point of tracking the steps separately.

Worked example. Suppose 100,000 sessions produce 9,000 with an add-to-cart, a 9% rate. Of those, 3,000 reach checkout and 1,800 buy. The add-to-cart step is healthy; the steep drop from cart to checkout is where the money leaks — likely a shipping surprise or a forced account creation.

Splitting the funnel this way turns one vague conversion rate into a map of exactly where to work.
Failure modes to watch. Reading add-to-cart rate without the steps after it; celebrating a high rate that comes from an aggressive auto-add or pre-filled cart; and comparing rates across traffic sources with very different intent as if they were equivalent.

Common questions

What is a good add-to-cart rate?
It varies widely by category, price point, and traffic source, so compare to your own segment and trend. Read it alongside checkout and purchase rates to locate the real leak.
Add-to-cart rate vs conversion rate?
Add-to-cart rate measures an early commitment; conversion rate measures the completed purchase. The gap between them is your cart-and-checkout abandonment.
How do I improve add-to-cart rate?
Work the product and listing page — clearer pricing, stronger imagery, an obvious button, and trust signals — before touching checkout, which affects later steps.
