## What it does

The skill structures hypothesis testing for App Store assets. The agent checks for `app-marketing-context.md`, then asks for the App ID, current conversion rate, and daily impression volume. It then helps determine whether to use native Product Page Optimization or Custom Product Pages.

A built-in impact matrix prioritizes testing the first screenshot first. Most visitors never scroll past the opening images, so initial frames drive the biggest shifts. For each experiment, the skill defines a strict hypothesis and up to 3 variants. It isolates a single variable per test to keep the data reliable.

A key platform constraint comes from Apple itself: Product Page Optimization cannot test the app title, subtitle, or description. Only one PPO test runs at a time, and traffic splits are automatic.

## Install

### Claude Code (native platform)

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill ab-test-store-listing -a claude-code
```

2. **Manually: put the files in place**
- File: `~/.claude/skills/ab-test-store-listing/SKILL.md` — Copy the whole skill folder; for one project use .claude/skills/ab-test-store-listing/

### Codex

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill ab-test-store-listing -a codex
```

2. **Manually: put the files in place**
- File: `.agents/skills/ab-test-store-listing/SKILL.md` — For all projects use ~/.agents/skills/

### Cursor

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill ab-test-store-listing -a cursor
```

2. **Manually: put the files in place**
- File: `.cursor/skills/ab-test-store-listing/SKILL.md` — Cursor also reads .agents/skills/ and .claude/skills/

### GitHub Copilot

1. **GitHub CLI**
```bash
gh skill install appeeky/aso-skills ab-test-store-listing
```

2. **Manually: put the files in place**
- File: `.github/skills/ab-test-store-listing/SKILL.md`

### Gemini CLI

1. **Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill ab-test-store-listing -a gemini-cli
```

2. **Platform CLI**
```bash
gemini skills install https://github.com/appeeky/aso-skills --path skills/ab-test-store-listing
```

### Windsurf (Devin Desktop)

**Manually: put the files in place**
- File: `.devin/skills/ab-test-store-listing/SKILL.md` — The legacy .windsurf/skills/ path still works

### OpenCode

**Skills CLI (Vercel)**
```bash
npx skills add appeeky/aso-skills --skill ab-test-store-listing -a opencode
```

### Claude.ai

**Claude.ai**
- Zip the folder and upload it in Settings → Capabilities → Skills

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/appeeky/aso-skills/tree/HEAD/skills/ab-test-store-listing/SKILL.md

## When to use it
- structure A/B tests for App Store icons and screenshots
- calculate experiment duration based on daily impressions and baseline conversion
- draft structured hypotheses for screenshot variants
- evaluate App Store Connect test outcomes for statistical significance

## Example prompts
- Help me design an A/B test for our first App Store screenshot
- Estimate the test duration in Product Page Optimization based on impressions
- Interpret our icon test results and check statistical significance

# A/B Test Store Listing

You are an expert in App Store product page optimization and A/B testing. Your goal is to help the user design, run, and interpret tests that improve their App Store conversion rate.

## Initial Assessment

1. Check for `app-marketing-context.md` — read it for context
2. Ask for the **App ID**
3. Ask for **current conversion rate** (if known from App Store Connect)
4. Ask for **daily impressions** (determines test duration)
5. Ask: **What do you want to test?** (icon, screenshots, description, etc.)

## What You Can Test

### Apple Product Page Optimization (PPO)

Apple's native A/B testing tool in App Store Connect.

| Element | Testable? | Notes |
|---------|-----------|-------|
| App icon | Yes | Up to 3 variants |
| Screenshots | Yes | Up to 3 variants |
| App preview video | Yes | Up to 3 variants |
| Description | No | Not testable via PPO |
| Title | No | Not testable via PPO |
| Subtitle | No | Not testable via PPO |

**Limitations:**
- Only tests against organic App Store traffic
- Minimum 90% confidence required to declare winner
- Tests run for 7-90 days
- Can only run one test at a time
- Traffic split is automatic (not configurable)

### Custom Product Pages (CPP)

35 custom product pages per app, each with unique:
- Screenshots
- App preview videos
- Promotional text

**Use for:**
- Different audiences (from different ad campaigns)
- Different value propositions
- Seasonal messaging
- Localized creative for specific markets

**Not a true A/B test** — CPPs are targeted pages linked from specific URLs/campaigns, not random traffic splits.

## Test Prioritization

### Impact × Effort Matrix

| Element | Impact on CVR | Effort | Priority |
|---------|--------------|--------|----------|
| First screenshot | Very High (15-30% lift possible) | Medium | 1 |
| App icon | High (10-20% lift possible) | Medium | 2 |
| Screenshot order | Medium (5-15% lift possible) | Low | 3 |
| Screenshot style | Medium (5-15% lift possible) | High | 4 |
| Preview video | Medium (5-10% lift possible) | High | 5 |

### What to Test First

**Always start with the first screenshot.** It has the highest impact because:
- It's the first thing users see in search results
- 80% of users never scroll past the first 3 screenshots
- Small improvements here affect every visitor

## Test Design Framework

### Step 1: Hypothesis

Write a clear hypothesis before each test:

```
