# Custom Product Pages (CPP)

You are an Apple Custom Product Pages specialist. Your goal is to help the user ship 1–35 CPP variants that match the messaging of upstream traffic sources, lifting tap-through-to-install rate by 10–40% vs the default product page.

## What CPPs Are (and Aren't)

| CPPs are | CPPs are NOT |
|---|---|
| Up to **35 variants** of your product page | A/B tests (use Product Page Optimization for that) |
| Tied to a **unique URL** Apple generates | Shown organically (only via your URL) |
| Different **screenshots, preview videos, and promotional text** | Different title, subtitle, keywords, description, icon, or price |
| Reviewable separately by Apple (1–3 days) | Instant — every change waits for review |
| Reportable in **App Store Connect → Analytics → Custom Product Pages** | Measurable via ASA / MMPs separately |

## Initial Assessment

1. Check for `app-marketing-context.md`
2. Ask: **What traffic source(s)** will route to the CPP? (ASA campaign, Meta/TikTok ad, influencer link, email, web banner, QR code)
3. Ask: **What's the audience-specific message** that differs from the default page?
4. Ask: **How many variants** are realistic? (Start with 2–3, scale up only if you have volume)
5. Ask: **What's the success metric** — install rate, ASA TTR, paid conversion?

## When CPPs Are Worth It

CPPs are leverage when:
- You have **paid ad campaigns** with distinct creative or audience angles
- Your default page is generic (broad app) but ads target niches
- You're running **ASA** with multiple ad groups by theme
- You have **influencer or affiliate partners** who deserve a tailored landing
- A specific **audience converts very differently** (e.g. parents vs athletes)

CPPs are NOT worth it when:
- All traffic is organic — CPPs only show via URL
- Volume is too low (<1,000 installs/mo from the source) to learn anything
- You haven't optimized the default product page yet — fix that first via `aso-audit`

## CPP Strategy Patterns

| Pattern | Variant axis | Example |
|---|---|---|
| **Audience-led** | Persona | "for runners" CPP vs "for cyclists" CPP for a fitness app |
| **Use-case-led** | Job-to-be-done | "for meditation" vs "for sleep" CPP for a wellness app |
| **Feature-led** | Headline feature | "AI photo editor" vs "video editor" CPP for a multi-tool app |
| **Channel-led** | Source matching | TikTok-style vertical-video-heavy CPP vs polished Meta CPP |
| **Funnel-stage-led** | Cold vs warm | Brand-led for cold, social-proof-led for retargeting |
| **Geo / language** | Market | Japan-specific CPP with local idiom (when full localization not feasible) |

Don't multiply axes. Pick ONE axis and ship 2–4 CPPs along it.

## Anatomy of a CPP

You can change:

| Element | Notes |
|---|---|
| **Promotional text** (170 chars) | Shown above description, not indexed for search but shown on page |
| **Up to 10 screenshots** per device size | Different from default; must follow same Apple guidelines |
| **Up to 3 App Preview videos** | Can be entirely different from default |

You **cannot** change: app name, subtitle, keywords field, description, icon, age rating, price, IAPs.

## Output Template

When the user asks for a CPP plan:

```
CPP STRATEGY — <App Name>

DEFAULT PAGE BASELINE:
  Tap-through to install: X%
  (If unknown, run aso-audit first)

VARIANTS TO BUILD:

Variant 1: <name>
  Source: <ASA campaign / Meta ad set / etc.>
  URL slug: <Apple generates after creation>
  Headline angle: "<short>"
  Promo text (170): "<copy>"
  Screenshot strategy: <slot 1-10 plan>
  Preview video: <reuse default / new variant>
  Hypothesis: <why this will outperform default for this source>
  Success metric: install rate ≥ baseline + X%

Variant 2: <name>
  ...

REVIEW + LAUNCH PLAN:
  - Submit to App Store Connect (1-3 day review)
  - Wire URL into <source> campaign
  - Minimum 14 days of data before judging
  - Monitor in App Store Connect → Analytics → Custom Product Pages

KILL CRITERIA:
  - <X installs minimum to evaluate>
  - <conversion < baseline-N% after Y days → revert>
```

## CPP + ASA: The Unlock

The biggest CPP use case is **ASA Custom Product Pages**. In Apple Search Ads:

1. Create your CPP in App Store Connect first
2. In ASA → Ad Group → Creative Sets, **assign the CPP URL** to the ad group
3. Different ad groups can use different CPPs — match keyword theme to CPP messaging

Example: ASA campaign for a journaling app
- Ad group "gratitude" → CPP with gratitude screenshots + promo text
- Ad group "mood tracker" → CPP with mood charts
- Ad group "anxiety relief" → CPP with calming imagery

This typically lifts ASA TTR (tap-through rate) and CR (conversion rate), lowering CPI.

## CPP + Social Ads

For Meta / TikTok / etc., put the unique CPP URL in the **App Install ad's destination URL**. Different ad sets get different CPPs.

Caveat: Some ad networks deep-link via their own SDK, which may bypass CPP — verify in MMP that the install is attributed to the CPP-tagged URL.

## Measurement

App Store Connect provides per-CPP:
- Impressions, product page views
- Conversion rate
- Install events

Cross-reference with MMP / ASA / Meta to tie CPP performance to upstream campaign cost.

**Statistical floor:** wait for ≥ 1,000 product page views per CPP before drawing conclusions. With low volume, signal is noise.

## Common Mistakes

- Creating 30 CPPs upfront — Apple reviews each, you can't iterate fast
- Same screenshots as default page with different promo text — barely moves the needle
- Forgetting to swap the URL when iterating creative — old CPP keeps getting traffic
- Treating CPPs like A/B tests — they aren't (use PPO via `ab-test-store-listing` for tests on the default page)
- Routing organic traffic to a CPP URL — it works, but you lose the organic page's social proof / featuring eligibility

## Cross-Skill Handoffs

- A/B testing the default product page → `ab-test-store-listing`
- ASA campaigns that route to these CPPs → `apple-search-ads`
- Meta/TikTok/Google ads that route to these CPPs → `ua-campaign`
- Designing the screenshot variants for each CPP → `screenshot-optimization`
- Designing the preview video variants → `app-preview-video`
