Which metric might a client focus on for e-commerce performance?

• A. Email signups
• B. Add to cart
• C. Revenue per visitor
• D. Customer satisfaction score

Answer: (B)

In e-commerce analytics, you want a metric that shows how shoppers are moving toward a purchase, not just end results or marketing engagement. Add-to-cart captures that moment of intent: a visitor signals interest by selecting a product and placing it in the cart, indicating they’re considering buying. This mid-funnel action is highly actionable because you can directly influence it with on-site improvements—product page clarity, pricing visibility, shipping information, and streamlining the cart and checkout process. It also supports interventions like cart reminders or targeted offers to reduce friction and push toward checkout, making it a strong predictor of future sales.

Revenue per visitor is valuable but reflects actual purchases and can be affected by price changes or promotions, meaning it’s a downstream outcome. Email signups measure marketing reach rather than immediate purchasing behavior, and the customer satisfaction score focuses on post-purchase experience rather than current shopping activity. So, tracking add-to-cart provides a direct, actionable view of shopper intent and funnel progression, guiding practical optimization for conversions.
