Which KPI is most appropriate to measure the success of an e-commerce optimization activity aimed at reducing cart abandonment?

Question

Options

• APage Views
• BAdd-to-Cart Rate
• CBounce Rate
• DCheckout Completion Rate

• A
  4% (2)
• B
  8% (4)
• C
  18% (9)
• D
  71% (36)

Explanation

Checkout Completion Rate directly measures how many users who initiated checkout actually completed a purchase - making it the ideal KPI for a cart abandonment reduction initiative, since a successful optimization would move this number upward.

Page Views (A) measures traffic volume, not purchase intent or conversion behavior, so it tells you nothing about whether cart abandonment improved. Add-to-Cart Rate (B) tracks users moving items into the cart, which happens before abandonment - improving it could actually increase abandonment in absolute terms. Bounce Rate (C) measures single-page exits before any shopping behavior begins, making it irrelevant to users who already reached the cart stage.

Memory tip: Think of the funnel stages - Browse → Add to Cart → Checkout → Purchase. Cart abandonment lives between "Checkout" and "Purchase," so your KPI must measure that final transition: Checkout Completion Rate.
