Consolidated PDP accordion stack

The old PDP had a long accordion of dropdowns competing for attention. Reducing them to two well-grouped sections and reorganising what lived inside each one cut the visual decision-cost — and the conversion math moved.

Cognitive ease

Hypothesis

IF we simplify and consolidate the dropdown section layout on the PDP by reducing the number of accordion items and reorganising the information inside each one, THEN ARPU will increase, BECAUSE a cleaner, more intuitive design reduces cognitive load and makes it easier to find relevant product information.

Voice note describing the product on men's PDP

Reading specs is work. A 20-second voice clip from the team explaining what makes the product different turned the PDP into a conversation — different sensory channel, lower cognitive load. Marginal in significance, but a real research insight worth publishing.

Dual-coding (auditory + visual)

Hypothesis

IF we provide a voice note describing the product on the PDP, THEN ARPU will increase, BECAUSE auditory information enhances user engagement and understanding (Dual Coding Theory), making the product more appealing and reducing decision-making time.
