App Store Listing Optimizer

Craft high-converting, keyword-optimized App Store and Google Play listings through competitive research, strategic keyword selection, and data-driven screenshot planning.

Prerequisites

  • Chrome browser with Claude in Chrome extension (for browsing competitor listings)
  • No API keys required — all research uses live store browsing
  • Supports iOS App Store, Google Play Store, or both

Workflow Overview

1. App Analysis        — Understand the app, audience, differentiators
2. Competitive Research — Browse competitor listings, extract keywords
3. Keyword Selection    — Identify high-intent, low-competition keywords
4. Craft the Listing    — Write optimized metadata for each platform
5. Screenshot Strategy  — Plan visual sequence and caption copy
6. A/B Test Variants    — Generate 2-3 alternatives for split testing

Step 1: Analyze the App

Gather everything needed to position the app effectively. Ask the user:

  1. What does the app do? One sentence, plain language.
  2. Target platform? iOS, Android, or both?
  3. Who is it for? Primary audience, age range, expertise level.
  4. Top 3 features — What does it do better or differently?
  5. Differentiator — Why pick this over competitors?
  6. Monetization — Free, freemium, subscription, one-time purchase?
  7. Current listing (if updating) — Share the existing store URL.

Document the answers in a structured brief before proceeding.

Step 2: Competitive Keyword Research

Browse 8-12 competitor listings on the target store(s) using Chrome. For detailed methodology and search patterns, see references/keyword-research.md.

What to Extract Per Competitor
FieldWhere to Find
App nameTitle on store listing
Subtitle / shortBelow title (iOS) or short desc (Android)
Full descriptionStore listing body
Rating + countStore listing header
Category rankStore listing or chart position
ScreenshotsVisual carousel — note caption text
Keyword Extraction Process
  1. List every keyword and phrase from competitor titles and subtitles.
  2. Scan descriptions for repeated terms — these are intentional keyword targets.
  3. Note caption text on competitor screenshots — often contains keyword variations.
  4. Build a master keyword list of 40-60 candidate terms.
Platform Differences
  • iOS: Only the app name, subtitle, and keyword field are indexed for search. The description is NOT searchable — it exists purely for conversion.
  • Google Play: The full description IS indexed. Keyword density matters, but avoid stuffing. The short description carries extra weight.

Step 3: Keyword Selection

Narrow the master list to the highest-value keywords.

Selection Criteria
FactorWhat to Look For
RelevanceDirectly describes what the app does or solves
IntentUser searching this term wants what the app offers
CompetitionFewer top-rated apps ranking for this term = better chance
VolumeTerm appears across multiple competitor listings
LengthLonger phrases (2-3 words) = lower competition, higher intent
Prioritization Tiers
  • Tier 1 (must use): High relevance + clear intent + moderate competition. Place in title or subtitle.
  • Tier 2 (strong): Good relevance + decent volume. Place in iOS keyword field or Google Play description.
  • Tier 3 (supplemental): Related terms, synonyms, adjacent use cases. Fill remaining keyword space.
iOS Keyword Field Rules

The 100-character keyword field has specific optimization rules:

  • Comma-separated, no spaces after commas (wastes characters)
  • Do NOT repeat words already in the app name or subtitle
  • Do NOT include the word "app" (Apple adds it automatically)
  • Do NOT include plurals if the singular is present (Apple handles this)
  • Do NOT include common prepositions or articles
  • Use singular forms only
  • Include competitor brand misspellings only if ethical and relevant
Google Play Keyword Strategy
  • No keyword field exists — optimize within the description text
  • Repeat primary keywords 3-5 times naturally across the full description
  • Place highest-priority keywords in the first paragraph and short description
  • Use keyword variations and synonyms throughout
  • Avoid keyword stuffing — Google penalizes unnatural density

Step 4: Craft the Listing

Write optimized metadata for each target platform.

App Name (both platforms: 30 characters max)
  • Include the primary keyword naturally
  • Lead with the brand name if it has recognition; otherwise lead with the keyword
  • Format options: BrandName - Keyword Phrase or Keyword Phrase: BrandName
  • Test readability — truncation happens around 20-25 chars in search results
iOS Subtitle (30 characters max)
  • Reinforce the value proposition with secondary keywords
  • Do NOT repeat words from the app name
  • Focus on benefit, not feature: "Sleep Better Tonight" > "Sleep Tracker App"
  • Every character counts — use the full 30
Google Play Short Description (80 characters max)
  • Searchable and prominently displayed — treat as a headline + subtitle combined
  • Include 1-2 primary keywords
  • Communicate the core value proposition
  • More space than iOS subtitle — use it to differentiate
iOS Keyword Field (100 characters max)

Apply the rules from Step 3. Present the final keyword string with character count. Example format:

sleep,tracker,insomnia,white,noise,meditation,relax,bedtime,routine,calm
(87/100 characters)
Full Description

iOS (not searchable — optimize for conversion):

  • First 3 lines appear before "Read More" — hook immediately
  • Lead with the strongest benefit statement
  • Use short paragraphs and line breaks for scannability
  • Include social proof (awards, press, user count) early
  • End with a clear call to action
  • Unicode symbols (checkmarks, stars) draw the eye in bullet lists

Google Play (searchable — balance keywords + conversion):

  • First 3 lines appear before "Read More" — same hook principle
  • Weave primary keywords into the first paragraph naturally
  • Use keyword variations throughout (don't repeat the exact same phrase)
  • Structure: Hook > Features > Social proof > CTA
  • 4,000 character max — use 3,000-3,500 for optimal density
  • Include a "What's New" narrative for returning visitors
First 3 Lines Template

These lines appear in search results before the user taps "Read More." They must accomplish three things: (1) state the core benefit, (2) differentiate from competitors, (3) compel the tap.

{Primary benefit statement — what the user gets}
{Differentiator — why this app, not the others}
{Social proof or specificity — numbers, awards, or unique method}

Step 5: Screenshot Strategy

Plan the visual sequence for maximum conversion. For detailed caption formulas, device specs, and sequence patterns, see references/screenshot-formulas.md.

Key Principles
  • First 3 screenshots appear in search results — they must tell the story alone
  • Screenshot 1 is the most important asset in your entire listing
  • Show the app in action, not splash screens or logos
  • Every screenshot needs a caption — text above or below the device frame
  • Social proof screenshots (ratings, user count) measurably increase conversion
  • App preview videos autoplay in iOS search results — consider one if the app has visual appeal
PositionPurposeCaption Focus
1Hero / primary benefitStrongest value proposition
2Key feature #1Most differentiating feature
3Key feature #2Second strongest feature
4Social proofRatings, user count, press quote
5Feature #3Unique capability
6Customization / UIShow personalization options
7Before/after or resultOutcome the user achieves
8Pricing / valueWhat they get for the price
9-10Additional featuresRemaining noteworthy capabilities
Platform-Specific Limits
  • iOS: Up to 10 screenshots per device type. First 3 shown in search.
  • Google Play: Up to 8 screenshots per device type. First 3-4 shown in search. Feature graphic (1024x500) is required and prominently displayed.

Step 6: A/B Test Variants

Generate 2-3 alternatives for the highest-impact elements. Present all variants in a comparison table.

What to Test (in priority order)
  1. App subtitle / short description — Highest impact on conversion from search results
  2. First 3 description lines — Controls "Read More" tap-through rate
  3. Screenshot 1 caption — First visual impression
  4. App name keyword — Only test if willing to change the indexed name
Variant Generation Rules
  • Each variant should test ONE hypothesis (benefit-led vs feature-led, emotional vs rational, specific vs broad)
  • Keep variants meaningfully different — changing one word is not a real test
  • Label variants clearly: Variant A (control), Variant B, Variant C
  • Note the hypothesis each variant tests
Output Format
## A/B Test Plan

### Subtitle Variants (iOS)

| Variant | Text                 | Hypothesis           | Chars |
| ------- | -------------------- | -------------------- | ----- |
| A       | {current or default} | Benefit-focused      | XX/30 |
| B       | {alternative}        | Feature-focused      | XX/30 |
| C       | {alternative}        | Social-proof-focused | XX/30 |

### First 3 Lines Variants

| Variant | Lines          | Hypothesis       |
| ------- | -------------- | ---------------- |
| A       | {3-line block} | Emotional hook   |
| B       | {3-line block} | Data-driven hook |

### Screenshot 1 Caption Variants

| Variant | Caption   | Hypothesis      |
| ------- | --------- | --------------- |
| A       | {caption} | Problem-focused |
| B       | {caption} | Outcome-focused |

Localization Notes

  • Localizing the listing into 5-10 languages multiplies keyword reach significantly — each locale has its own keyword index
  • Prioritize: Spanish, French, German, Japanese, Korean, Portuguese, Chinese (Simplified)
  • At minimum, localize the app name, subtitle, keywords, and first 3 description lines
  • Google Play auto-translates listings but manual localization always outperforms
  • Each locale can target entirely different keywords for the same app

| **Intent**      | User searching this term wants what the app offers            |
| **Competition** | Fewer top-rated apps ranking for this term = better chance    |
| **Volume**      | Term appears across multiple competitor listings              |
| **Length**      | Longer phrases (2-3 words) = lower competition, higher intent |

Write optimized metadata for each target platform.

### App Name (both platforms: 30 characters max)

- Include the primary keyword naturally
- Lead with the brand name if it has recognition; otherwise lead with the
  keyword
- Format options: `BrandName - Keyword Phrase` or `Keyword Phrase: BrandName`
- Test readability — truncation happens around 20-25 chars in search results

- Include 1-2 primary keywords
- Communicate the core value proposition
- More space than iOS subtitle — use it to differentiate

### iOS Keyword Field (100 characters max)

Apply the rules from Step 3. Present the final keyword string with character
count. Example format:

```
sleep,tracker,insomnia,white,noise,meditation,relax,bedtime,routine,calm
(87/100 characters)

- Structure: Hook > Features > Social proof > CTA
- 4,000 character max — use 3,000-3,500 for optimal density
- Include a "What's New" narrative for returning visitors

### First 3 Lines Template

These lines appear in search results before the user taps "Read More." They must
accomplish three things: (1) state the core benefit, (2) differentiate from
competitors, (3) compel the tap.

```
{Primary benefit statement — what the user gets}
{Differentiator — why this app, not the others}

## Step 5: Screenshot Strategy

Plan the visual sequence for maximum conversion. For detailed caption formulas,
device specs, and sequence patterns, see
[references/screenshot-formulas.md](references/screenshot-formulas.md).

### Key Principles

- **First 3 screenshots** appear in search results — they must tell the story

- Show the app in action, not splash screens or logos
- Every screenshot needs a caption — text above or below the device frame
- Social proof screenshots (ratings, user count) measurably increase conversion
- App preview videos autoplay in iOS search results — consider one if the app
  has visual appeal

### Recommended Sequence (5-10 screenshots)

| Position | Purpose                | Caption Focus                     |
| -------- | ---------------------- | --------------------------------- |
| 1        | Hero / primary benefit | Strongest value proposition       |
| 2        | Key feature #1         | Most differentiating feature      |
| 3        | Key feature #2         | Second strongest feature          |
| 4        | Social proof           | Ratings, user count, press quote  |
| 5        | Feature #3             | Unique capability                 |
| 6        | Customization / UI     | Show personalization options      |
| 7        | Before/after or result | Outcome the user achieves         |
| 8        | Pricing / value        | What they get for the price       |
| 9-10     | Additional features    | Remaining noteworthy capabilities |

### Platform-Specific Limits

- **iOS:** Up to 10 screenshots per device type. First 3 shown in search.
- **Google Play:** Up to 8 screenshots per device type. First 3-4 shown in
  search. Feature graphic (1024x500) is required and prominently displayed.
