Add-to-cart rate is the percentage of sessions where at least one product is added to the shopping cart. It measures the effectiveness of your product pages and merchandising in generating buying intent.
Why Add-to-Cart Rate matters
This metric is a leading indicator of purchase likelihood. If your add-to-cart rate is low, it’s a sign that visitors aren’t convinced by your product presentation, pricing, or perceived value. Improving this rate increases the number of potential checkouts, which in turn can lift total sales even if conversion rates remain constant.
How Add-to-Cart Rate works
Add-to-cart rate = (Sessions with Add-to-Cart ÷ Total Sessions) × 100%. Segment by product category, device, or traffic source to pinpoint strengths and weaknesses. This rate can be influenced by product photography, descriptions, price transparency, stock levels, and trust signals.
Example in ecommerce
A beauty brand sees an add-to-cart rate of 4% on desktop and 1.5% on mobile. Mobile PDPs are redesigned with faster load speeds, larger “Add to Cart” buttons, and visible shipping info. Mobile add-to-cart rate jumps to 3.2%, increasing checkout starts by 20%.
Common mix-ups
Add-to-cart rate is not conversion rate, adding a product to the cart is an expression of intent, not a completed purchase. It also differs from checkout initiation rate, which measures when customers begin checkout.
