  • WHO: E-commerce & CRO teams
  • INDUSTRY: Retail
  • IMPACTED PAGES: Product Detail Pages, Subscription pages

Experiment 1: Adding a refill quantity selector to the subscription page

Hypothesis: If a brush refill quantity selector is added to the product detail page, then conversion rates and subscription units will increase because users will have more control over their purchase and see clearer value in subscribing.

Faster time to launch tests

Takeaways:

  1. Adding a refill quantity selector increased conversion rates by +4.7%, showing that customer choice directly boosts engagement.
  2. Experiments launched at higher velocity (60+ total, 40x faster A/B testing) reinforced that decentralizing testing accelerates product development.
  3. Subscription units per transaction rose, highlighting that small UX enhancements can meaningfully improve customer retention strategies.

Experiment 2: Positioning a free trial as a built-in feature

Hypothesis: If a free trial is offered and positioned as a built-in feature rather than an add-on, enrollment will increase because trial framing reduces perceived risk and highlights convenience.
