App Store Optimization (ASO)

Keyword Research Workflow

Discover and evaluate keywords that drive app store visibility.

Workflow: Conduct Keyword Research

1. Define target audience and core app functions:

- Primary use case (what problem does the app solve) - Target user demographics - Competitive category

1. Generate seed keywords from:

- App features and benefits - User language (not developer terminology) - App store autocomplete suggestions

1. Expand keyword list using:

- Modifiers (free, best, simple) - Actions (create, track, organize) - Audiences (for students, for teams, for business)

1. Evaluate each keyword:

- Search volume (estimated monthly searches) - Competition (number and quality of ranking apps) - Relevance (alignment with app function)

1. Score and prioritize keywords:

- Primary: Title and keyword field (iOS) - Secondary: Subtitle and short description - Tertiary: Full description only

1. Map keywords to metadata locations
2. Document keyword strategy for tracking
3. Validation: Keywords scored; placement mapped; no competitor brand names included; no plurals in iOS keyword field

Keyword Evaluation Criteria

Keyword Placement Priority

See: references/keyword-research-guide.md

Metadata Optimization Workflow

Optimize app store listing elements for search ranking and conversion.

Workflow: Optimize App Metadata

1. Audit current metadata against platform limits:

- Title character count and keyword presence - Subtitle/short description usage - Keyword field efficiency (iOS) - Description keyword density

1. Optimize title following formula:

   [Brand Name] - [Primary Keyword] [Secondary Keyword]

1. Write subtitle (iOS) or short description (Android):

- Focus on primary benefit - Include secondary keyword - Use action verbs

1. Optimize keyword field (iOS only):

- Remove duplicates from title - Remove plurals (Apple indexes both forms) - No spaces after commas - Prioritize by score

1. Rewrite full description:

- Hook paragraph with value proposition - Feature bullets with keywords - Social proof section - Call to action

1. Validate character counts for each field
2. Calculate keyword density (target 2-3% primary)
3. Validation: All fields within character limits; primary keyword in title; no keyword stuffing (>5%); natural language preserved

Platform Character Limits

Description Structure

PARAGRAPH 1: Hook (50-100 words)
├── Address user pain point
├── State main value proposition
└── Include primary keyword

PARAGRAPH 2-3: Features (100-150 words)
├── Top 5 features with benefits
├── Bullet points for scanability
└── Secondary keywords naturally integrated

PARAGRAPH 4: Social Proof (50-75 words)
├── Download count or rating
├── Press mentions or awards
└── Summary of user testimonials

PARAGRAPH 5: Call to Action (25-50 words)
├── Clear next step
└── Reassurance (free trial, no signup)

See: references/platform-requirements.md

Competitor Analysis Workflow

Analyze top competitors to identify keyword gaps and positioning opportunities.

Workflow: Analyze Competitor ASO Strategy

1. Identify top 10 competitors:

- Direct competitors (same core function) - Indirect competitors (overlapping audience) - Category leaders (top downloads)

1. Extract competitor keywords from:

- App titles and subtitles - First 100 words of descriptions - Visible metadata patterns

1. Build competitor keyword matrix:

- Map which keywords each competitor targets - Calculate coverage percentage per keyword

1. Identify keyword gaps:

- Keywords with <40% competitor coverage - High volume terms competitors miss - Long-tail opportunities

1. Analyze competitor visual assets:

- Icon design patterns - Screenshot messaging and style - Video presence and quality

1. Compare ratings and review patterns:

- Average rating by competitor - Common praise themes - Common complaint themes

1. Document positioning opportunities
2. Validation: 10+ competitors analyzed; keyword matrix complete; gaps identified with volume estimates; visual audit documented

App Launch Workflow

Execute a structured launch for maximum initial visibility.

Workflow: Launch App to Stores

1. Complete pre-launch preparation (4 weeks before):

- Finalize keywords and metadata - Prepare all visual assets - Set up analytics (Firebase, Mixpanel) - Build press kit and media list

1. Submit for review (2 weeks before):

- Complete all store requirements - Verify compliance with guidelines - Prepare launch communications

1. Configure post-launch systems:

- Set up review monitoring - Prepare response templates - Configure rating prompt timing

1. Execute launch day:

- Verify app is live in both stores - Announce across all channels - Begin review response cycle

1. Monitor initial performance (days 1-7):

- Track download velocity hourly - Monitor reviews and respond within 24 hours - Document any issues for quick fixes

1. Conduct 7-day retrospective:

- Compare performance to projections - Identify quick optimization wins - Plan first metadata update

1. Schedule first update (2 weeks post-launch)
2. Validation: App live in stores; analytics tracking; review responses within 24h; download velocity documented; first update scheduled

Launch Timing Considerations

See: references/aso-best-practices.md

A/B Testing Workflow

Test metadata and visual elements to improve conversion rates.

Workflow: Run A/B Test

1. Select test element (prioritize by impact):

- Icon (highest impact) - Screenshot 1 (high impact) - Title (high impact) - Short description (medium impact)

1. Form hypothesis:

   If we [change], then [metric] will [improve/increase] by [amount]
   because [rationale].

1. Create variants:

- Control: Current version - Treatment: Single variable change

1. Calculate required sample size:

- Baseline conversion rate - Minimum detectable effect (usually 5%) - Statistical significance (95%)

1. Launch test:

- Apple: Use Product Page Optimization - Android: Use Store Listing Experiments

1. Run test for minimum duration:

- At least 7 days - Until statistical significance reached

1. Analyze results:

- Compare conversion rates - Check statistical significance - Document learnings

1. Validation: Single variable tested; sample size sufficient; significance reached (95%); results documented; winner implemented

Test Documentation Template

TEST ID: ASO-2025-001
ELEMENT: App Icon
HYPOTHESIS: A bolder color icon will increase conversion by 10%
START DATE: [Date]
END DATE: [Date]

RESULTS:
├── Control CVR: 4.2%
├── Treatment CVR: 4.8%
├── Lift: +14.3%
├── Significance: 97%
└── Decision: Implement treatment

LEARNINGS:
- Bold colors outperform muted tones in this category
- Apply to screenshot backgrounds for next test

Platform Notes

When not to use this skill: web apps (use web SEO), enterprise/internal apps, TestFlight-only betas, or paid advertising strategy.

Proactive Triggers

• No keyword optimization in title → App title is the #1 ranking factor. Include top keyword.
• Screenshots don't show value → Screenshots should tell a story, not show UI.
• No ratings strategy → Below 4.0 stars kills conversion. Implement in-app rating prompts.
• Description keyword-stuffed → Natural language with keywords beats keyword stuffing.

Output Artifacts

Communication
