TL;DR
ASO is how users find your app. With millions of apps in each store, visibility determines downloads more than quality alone.
- Keywords drive discovery — Research what users actually search for
- Title and subtitle matter most — Front-load with primary keywords
- Screenshots sell the download — Users decide in 3 seconds
- Reviews affect rankings — Both quantity and sentiment
- Localization multiplies reach — Same effort, new markets
Why ASO Matters
App Store Optimization is SEO for app stores. When users search "budget tracker" or "meditation app," ASO determines whether your app appears on page one or page twenty.
The numbers:
- 65% of app downloads come from app store search
- Top 3 search results get 50%+ of downloads
- Moving from position 10 to position 3 can 5x your organic installs
Unlike paid ads, ASO improvements compound over time. One hour of optimization work can drive downloads for years.
Tactic 1: Keyword Research
Keywords are how users find apps. Your intuition about what users search isn't enough — you need data.
How to find keywords:
- Start with your app's core function — What problem does it solve?
- Use App Store Connect / Google Play Console — Both show search terms that led to your app
- Check competitor metadata — What keywords do top apps in your category target?
- Use ASO tools — Sensor Tower, App Radar, or AppTweak show search volume and difficulty
Example: A recipe app might think users search "recipes." Data shows "quick dinner ideas," "meal prep," and "healthy recipes under 30 minutes" have higher intent and lower competition.
What to target:
- High search volume (people actually search this)
- Low competition (you can rank)
- High relevance (matches what your app does)
Tactic 2: Optimize Your Title and Subtitle
Your app title is the most important ranking factor. Apple gives you 30 characters; Google gives you 50.
Best practices:
- Lead with your brand — If it's recognizable
- Include primary keyword — The term with highest volume
- Make it readable — Don't keyword stuff
Examples:
| Before | After |
|--------|-------|
| MoneyMinder | MoneyMinder: Budget Tracker |
| RecipeBox | RecipeBox - Meal Planner |
| FitDaily | FitDaily: Home Workouts |
Subtitle (iOS) / Short Description (Android):
Use this for secondary keywords. You have 30 characters (iOS) or 80 characters (Android).
Don't: "The best app for everything you need"
Do: "Track spending, save more money"
Tactic 3: Write a Better Description
The long description doesn't directly affect iOS rankings, but it does affect Android rankings and conversion rates on both platforms.
Structure that works:
- First line — Clear value proposition (this shows before "Read More")
- Features list — Bullet points with keywords
- Social proof — Press mentions, awards, user count
- Call to action — What to do next
Keyword placement:
- Include target keywords naturally in the first 250 characters
- Repeat primary keywords 3-5 times throughout
- Don't stuff — Google penalizes obvious manipulation
Tactic 4: Optimize Screenshots and Video
Users spend 3-7 seconds on your app store page before deciding. Screenshots are often the deciding factor.
What works:
- First two screenshots — Show your #1 and #2 features (these appear in search results)
- Add text overlays — Explain what the screenshot shows
- Show the app in use — Not just UI, but UI with realistic content
- Use device frames — Looks more professional
Video preview:
- Keep it under 30 seconds
- Show the app working, not a brand video
- Front-load the best feature (most users don't finish)
Testing: Run A/B tests on screenshots using Google Play Experiments or App Store product page optimization.
Tactic 5: Leverage Reviews for Rankings
Reviews affect ASO in multiple ways:
- Direct ranking factor — Apps with more (and better) reviews rank higher
- Keyword signals — Words in reviews influence what searches you appear for
- Conversion rate — Users check ratings before downloading
How to improve review metrics:
- Ask at the right time — After a successful action, not on first launch
- Use in-app prompts — iOS allows 3 per year per user
- Respond to reviews — Shows active development, can prompt updates
- Fix issues mentioned in reviews — Reduces new negative reviews
How AppReviewBot helps:
- Get notified of new reviews in Slack/Teams
- Track rating trends over time
- Respond quickly to prevent churn
- Identify keyword opportunities from review text
Tactic 6: Localize for New Markets
Localization is the highest-ROI ASO tactic for apps with international potential. You do the work once and reach entirely new user bases.
What to localize:
- App name and subtitle — Translate and adapt keywords
- Description — Full translation with local keywords
- Screenshots — Translate text overlays
- Keywords field (iOS) — Research local search terms
Priority markets by language:
- English (US, UK, Australia, Canada)
- Spanish (Spain, Mexico, Latin America)
- German (Germany, Austria, Switzerland)
- Japanese
- Portuguese (Brazil)
Important: Don't just translate — localize. Keywords that work in US English often don't work in British English. "Apartment" vs "Flat" changes search behavior entirely.
Tactic 7: Update Regularly
App stores favor actively maintained apps. Regular updates signal quality and ongoing development.
Update strategy:
- Frequency — At least monthly for most apps
- Release notes — Include keywords naturally ("Fixed crash in budget tracker")
- Feature releases — Announce improvements, not just bug fixes
- Seasonal updates — Holiday themes, timely features
Warning: Bad updates hurt more than no updates. Monitor reviews closely after each release. A buggy update can tank your rating quickly.
Measuring ASO Success
Track these metrics weekly:
| Metric | What It Tells You |
|--------|-------------------|
| Keyword rankings | Are you moving up for target terms? |
| Organic downloads | Are more people finding you? |
| Conversion rate | Are visitors becoming users? |
| Rating trend | Is user satisfaction improving? |
Tools for tracking:
- App Store Connect / Google Play Console (free)
- Sensor Tower, AppTweak, App Radar (paid, more detailed)
- AppReviewBot (review monitoring and sentiment)
Key Takeaways
- ASO compounds — Small improvements accumulate over time
- Keywords first — Research before optimizing
- Title is king — Highest-impact single change
- Screenshots sell — Invest in good visuals
- Reviews matter — For rankings and conversion
- Localize strategically — Same work, bigger audience
- Monitor everything — You can't improve what you don't measure
Next Steps
Ready to improve your app's visibility?
- Audit your current metadata — How does your title compare to competitors?
- Research 5-10 target keywords — Use tools or competitor analysis
- Update your first 2 screenshots — Make them self-explanatory
- Set up review monitoring — Try AppReviewBot to track rating trends
- Pick one market to localize — Start with the biggest opportunity
ASO isn't a one-time task. The apps that rank highest treat optimization as an ongoing process — testing, measuring, and improving continuously.
