Does a complete goal-to-phrase opening pair explain the needs-led proposition better than the current choice-and-social-proof pair?
- Audience
- Eligible US English iPhone default-page visitors, with separate research among travel-focused, self-study and returning learners.
- Control
- The intact first two frames after verifying the all-levels and scale claims remain accurate.
- Treatment
- Replace the entire opening pair with one verified travel-goal-to-lesson journey; retain the third frame, metadata and later assets.
- Method
- Validate course access and connected composition, then use eligible App Store product page optimization. This compares complete pair concepts, not a single headline or a measured teaching method.
- Primary measure
- Platform-reported download conversion for eligible randomized traffic.
- Guardrails
- Participants should identify the first practice action without expecting every language, level or feature to be available on the same terms. Learning progress requires separate evidence.
- Decision rule
- Specify useful effect, sample requirement and analysis timing from real baseline traffic. Keep control if inconclusive and avoid generalising a travel-led result to exam preparation.
- What could muddy the result
- Course changes, travel season, language mix and returning-learner campaigns can alter the result.
