CPP, PPO, and Store Listing Tests

Use this for App Store Custom Product Pages, Product Page Optimization tests, product page variants, campaign pages, and conversion test planning.

MCP workflow

1. Use app-store-connect-mcp.
2. CPP/PPO tools are planned later. If a CPP/PPO tool exists, read the current page/test before editing.
3. If no CPP/PPO MCP tool exists in the active localhost server, produce a save-ready plan and clearly say live fill is not available yet.
4. Never overwrite default product page metadata while editing a CPP/PPO draft unless the user explicitly asks.

Decide the object

• PPO: native App Store A/B test against the default product page.
• CPP: targeted product page for a campaign, ad group, audience, keyword cluster, country, creator/partner link, or seasonal moment.
• Google Play Store Listing Experiment: use android-aso for Play-specific experiments.

Apple PPO facts

• Tests app icons, screenshots, and app previews.
• Up to 3 treatments per test.
• You choose the traffic proportion shown test treatments.
• Tests run for up to 90 days or until manually stopped.
• App Analytics may label results when confidence reaches 90%.
• PPO is not available for custom product pages, Apple Watch product pages, or iMessage product pages.
• App icon variants must be included in the current app binary and meet icon requirements.

Apple CPP facts

• Up to 70 custom product pages per app.
• Each page can vary screenshots, app previews, promotional text, and keywords.
• CPPs are targeted pages with unique URLs; they are not randomized A/B tests.
• CPPs can be used in Apple Ads and can appear in relevant search results when configured with keywords.
• CPP metadata must be approved before it is visible.

Test design framework

Write the hypothesis before variants:

If we [change], then [metric] will improve because [reason].

Good tests:

• Change one primary thing at a time.
• Make the variant meaningful enough to detect.
• Tie each variant to a user intent or conversion blocker.
• Define baseline, success metric, target locale/country, and minimum practical lift.
• Decide the confidence threshold and minimum runtime before launch; for PPO, treat 90% confidence as a minimum practical bar unless the user provides another standard.
• Avoid stopping early just because results look promising.
• Document the result and learning even when the test is inconclusive.

Test prioritization

Element	Why test it
App icon	Often high impact in search/listing attention; requires binary support for PPO icon tests
First screenshot	High impact in search and product page scanning
Screenshot order	Low effort, clarifies value sequence
Screenshot style/message	Tests benefit vs feature, proof vs workflow, audience angle
App preview	Useful when motion explains value better than stills

Do not promise lift percentages without app-specific data.

Strategy checklist

• Goal: conversion lift, ad relevance, market launch, seasonal campaign, or feature adoption.
• Audience: one intent segment per page/treatment.
• Traffic source: Search Ads, social ads, web, influencer, owned channel, or organic test.
• Locale and country are explicit.
• Screenshots and app previews match the promise in ad/keyword copy.
• Metadata does not make claims unsupported by the app or assets.
• Existing impressions/downloads are enough to run a meaningful PPO test, or the plan acknowledges low-sample risk.
• CPP performance is measured by page views, downloads, conversion, and downstream quality, not just click volume.

Result interpretation

When results are available:

• Check confidence, conversion rate, and confidence interval/uncertainty.
• Compare by territory, source type, device, and localization when available.
• For CPP, compare traffic quality and downstream events, subscriptions, or sales if available.
• Decide: apply winner, iterate, keep current, or run a new hypothesis.
• Do not apply a treatment if results are inconclusive or the winning segment is not the target segment.

Rules

• Keep each CPP/PPO variant focused on one promise.
• Do not duplicate the default page without a meaningful hypothesis.
• Do not invent performance metrics, audience data, or Search Ads results.
• For PPO, define the baseline and success metric before writing fields.
• For CPP, do not call it an A/B test unless traffic is externally randomized and measured.
• For Play Store experiments, use android-aso.
