ASO Optimization: The Ultimate Checklist for Indie Developers

I've launched 12 apps as an indie developer and PM. The first 3 failed miserably. The next 9 succeeded. The difference? A systematic approach to ASO (App Store Optimization).

Here's the exact checklist I use before every launch. Follow this, and you'll rank higher, convert better, and get more organic downloads.

Phase 1: Pre-Launch Research (Week 1-2)

Keyword Research

Goal: Find keywords you can actually rank for

✅ Use AppTweak or Sensor Tower to find:

• Search volume for your category keywords
• Keyword difficulty scores
• Competitor rankings

✅ Create a spreadsheet with:

• 10 high-volume keywords (10K+ searches/month)
• 20 medium-volume keywords (1K-10K)
• 30 long-tail keywords (100-1K)

Pro Tip: Long-tail keywords convert 2.5x better than generic terms. "Meditation app for anxiety" beats "meditation app" every time.

Competitor Analysis

Goal: Learn what's working in your category

✅ Download top 10 apps in your category ✅ Screenshot their store listings ✅ Analyze:

• What benefits do they lead with?
• What screenshots get the most attention?
• How do they structure their descriptions?
• What keywords are they targeting?

I use a simple scoring system: Rate each competitor 1-10 on:

• Icon design
• Screenshot quality
• Description clarity
• Social proof display

Then I aim to score 9-10 on everything my best competitor only scores 7-8 on.

Market Positioning

Goal: Find your unique angle

Ask yourself:

• What do I do that no one else does?
• What problem do I solve better?
• Who is my ideal user?

Write one sentence: "I help [specific user] do [specific thing] so they can [specific benefit]."

Example: "I help busy professionals meditate in 5 minutes so they can reduce stress without disrupting their day."

Phase 2: Asset Creation (Week 3-4)

App Name Optimization

Goal: Include your #1 keyword without sounding spammy

Formula: [Brand Name] - [Main Benefit/Keyword]

Good Examples:

• Calm - Sleep & Meditation
• Headspace - Mindfulness & Sleep
• Duolingo - Language Lessons

Bad Examples:

• Meditation Sleep Relax Yoga App (keyword stuffing)
• MeditatePro (no context)

Your Action:

• Primary keyword in name
• Keep under 30 characters
• Make it memorable

Subtitle Optimization (iOS)

Goal: Expand on value prop with more keywords

You get 30 characters. Use them wisely.

Formula: [Secondary benefit] + [social proof]

Examples:

• "5-Min Meditation - 10M Users"
• "Track Habits - Top Productivity App"
• "Learn Languages - #1 Education App"

Screenshot Creation

Goal: Show value in 7 screenshots

Use the 7-screenshot formula:

1. Hook - Biggest benefit
2. Problem/Solution - Show the pain point
3. Feature 1 - Your best feature
4. Feature 2 - Second-best feature
5. Social Proof - Ratings, testimonials
6. Use Case - Real-world scenario
7. CTA - Final conversion push

Design Checklist: ✅ High contrast text (80%+ opacity background) ✅ Readable on small screens (test on actual device) ✅ Consistent branding (same colors, fonts) ✅ Benefits, not features (focus on outcomes) ✅ No Lorem Ipsum or placeholder text ✅ Real UI or high-quality mockups

Tools I Use:

• Screenify (AI-generated in 30 seconds - shameless plug)
• Figma (if I need custom design)
• Canva (quick templates)

App Preview Video (Optional but Recommended)

Goal: 20-40% conversion boost

3 Rules:

1. First 3 seconds = hook (show the benefit immediately)
2. Keep it under 30 seconds (attention span)
3. Show real usage, not marketing fluff

I've tested this repeatedly: A simple screen recording with voiceover often outperforms expensive produced videos.

Phase 3: Description Optimization (Week 5)

Short Description (Google Play)

Goal: Convince in 80 characters

Formula: [What] for [Who] to [Benefit]

Example: "5-minute guided meditation for busy professionals to reduce stress and improve focus."

✅ Include primary keyword ✅ State clear benefit ✅ Mention target user

Long Description

Goal: Keyword-rich but readable

Structure:

1. Opening paragraph - Hook with main benefit
2. Features section - Bullet points, benefit-focused
3. Social proof - Users, ratings, awards
4. Use cases - "Perfect for..."
5. CTA - "Download now and..."

Keyword Strategy:

• Primary keyword in first sentence
• Secondary keywords in subheadings
• Long-tail keywords naturally throughout
• Keyword density: 2-3% (don't stuff)

My Template:

[App Name] helps you [main benefit] in just [time/effort investment].

Key Features: ✅ [Feature 1] - [Benefit] ✅ [Feature 2] - [Benefit]
✅ [Feature 3] - [Benefit]

Why Users Love [App Name]: ⭐ "[Testimonial]" - [User Name] ⭐ 4.8★ from 50,000+ reviews ⭐ Featured by Apple

Perfect For: • [Use case 1] • [Use case 2] • [Use case 3]

Download [App Name] today and start [benefiting] immediately!

Phase 4: Launch & Monitor (Week 6+)

Launch Checklist

✅ App Store Connect - All assets uploaded ✅ Google Play Console - Listing complete ✅ A/B test plan - 2-3 variations ready ✅ Analytics setup - Track everything ✅ Press kit - Ready for journalists ✅ Social media - Announcement posts scheduled

First 48 Hours

Critical Period: Apple/Google watch early performance

Your goal:

• 100+ downloads in first 24 hours
• 50+ ratings by day 3
• <5% crash rate
• Positive sentiment

How to get there:

1. Email your beta testers
2. Post in relevant communities
3. Ask friends/family to download
4. Reach out to app review sites

Do NOT:

• Buy fake reviews (instant rejection)
• Use incentivized downloads
• Ask for 5-star reviews specifically

Week 1-4: Monitor & Optimize

Daily Checks:

• Download numbers
• Conversion rate (impressions → downloads)
• Keyword rankings
• Reviews and ratings

Weekly Optimization:

• Test new screenshot variations
• Try different descriptions
• Adjust keyword targeting
• Respond to reviews

Phase 5: A/B Testing (Ongoing)

What to Test First

Highest Impact Changes:

1. Screenshot 1 - Your hook

   • Test different benefits
   • Try different visual styles
   • Test with/without text overlay

2. App Icon - First impression

   • Test different colors
   • Try abstract vs literal
   • Simplify vs detailed

3. App Name/Subtitle - Keyword targeting

   • Different keyword combinations
   • Various value props

How to Run Tests

iOS (App Store Connect):

• Go to App Store Connect
• Select "Product Page Optimization"
• Create up to 3 variations
• Test runs 90 days or until statistical significance

Android (Google Play Console):

• Go to "Store presence"
• Click "Experiments"
• Create variations for icon, screenshots, description
• Automatic traffic split

What I've Learned:

• Test one element at a time
• Need 1,000+ impressions per variation minimum
• Win rates of 5-10% are significant
• Sometimes "ugly" designs win (simplicity beats perfection)

Phase 6: Localization (Month 2-3)

Why Localize?

• 65% of users prefer apps in their language
• 30-100% increase in downloads per market
• Lower competition in non-English markets

Priority Markets

Start with:

1. Spanish - 400M+ potential users
2. Portuguese - Brazil market (huge Android user base)
3. German - High-value users
4. French - Growing market
5. Japanese - High-converting users

What to Localize

✅ Must Localize:

• App name (keep brand, translate subtitle)
• Screenshots (text overlay)
• Description (full translation)
• Keywords (research local terms)

❌ Don't Localize:

• Brand name/logo
• UI (unless you have budget)
• App preview video (expensive)

Tools:

• Google Translate (first pass)
• Professional translator (refinement)
• Local beta testers (validation)

Cost: $100-300 per language for store listing
