Does explanation-led ingredient wording improve understanding of the app’s ratings while preserving qualified conversion?
- Audience
- Eligible US English iPhone default-page visitors, with separate research among food-information and cosmetic-information prospects.
- Control
- The current second-frame headline only after appropriate review substantiates its scope; correct any unsupported claim across variants before establishing a baseline.
- Treatment
- Change only the second-frame headline to verified ingredient-information wording, keeping the result view, sequence, metadata and other assets fixed after checking accuracy.
- Method
- Verify the current method and explanation path, then use comprehension research and eligible App Store product page optimization. This tests wording, not nutritional science, ingredient safety or health outcomes.
- Primary measure
- Platform-reported download conversion for eligible randomized traffic.
- Guardrails
- Participants should distinguish an app rating from individual medical or allergy advice and know that product details need checking. No conversion result establishes safety or health benefit.
- Decision rule
- Predefine useful effect, sample requirement and analysis timing from baseline traffic. Keep control if inconclusive; reject a lift caused by stronger mistaken certainty about product suitability.
- What could muddy the result
- Database updates, product reformulations, method changes, media coverage and the food-versus-cosmetic audience mix may affect results.
