Does a seller-workflow third frame improve marketplace comprehension without reducing qualified buyer acquisition?
- Audience
- Eligible US English iPhone default-page visitors; comprehension research should recruit prospective buyers and prospective sellers separately.
- Control
- The captured fashion campaign, personalised feed and product-grid sequence.
- Treatment
- Replace only the third still with a verified listing draft showing representative photos and item details. Keep the campaign opener, second frame, metadata and offer fixed.
- Method
- Validate the current listing flow first, then run buyer/seller comprehension sessions and eligible randomized App Store product page optimization. Default-page test assignment does not itself reveal every visitor’s intent.
- Primary measure
- Platform-reported download conversion for eligible randomized visitors.
- Guardrails
- Buyers must still recognise fashion discovery; sellers must not expect guaranteed sales, fee-free transactions or universal protection. Track first-listing and shopping activation separately where valid attribution is available.
- Decision rule
- Predefine the useful effect and sample size from baseline traffic. Do not claim seller-specific lift from aggregate conversion; retain control if intent tradeoffs are unresolved or the result is inconclusive.
- What could muddy the result
- Fashion campaigns, seasonal inventory, shipping promotions, fee changes and shifts in buyer-versus-seller traffic may affect results.
