What is Checkout Velocity?
Checkout Velocity is the speed at which a user can seamlessly navigate from product discovery to a completed purchase. For D2C e-commerce stores, checkout velocity is heavily impacted by Navigation Latency-the hidden delay between a shopper clicking a link and the next page actually rendering on their mobile screen. Slow checkout velocity directly reduces Return on Ad Spend (ROAS).
