  2. Which mobile analytics event is most critical to track for optimizing a checkout funnel?

    A/B testing the home screen reveals which content hierarchy and design choices maximize clicks, add-to-carts, and revenue.

  7. An ecommerce brand launches a mobile loyalty program. Which in-app feature drives the highest repeat purchase rate?
