App Store Optimization isn't a mystery—it's a system. The 30-point audit breaks down your listing across five categories that directly predict store visibility and ranking.
The Five Pillars
Keyword Optimization (8 points)
Your title, subtitle, and keywords field form the indexing layer. App stores crawl these first.
- Title alignment: Does your primary keyword appear in the title?
- Subtitle leverage: The subtitle (30 chars on iOS) is often ignored—but it's free real estate for secondary keywords.
- Keywords field: 100 characters on iOS. Use them strategically.
Action: Run your listing through the Score Checker. Most apps leave 20–30% of keyword coverage unused.
Metadata Integrity (6 points)
Your screenshots, preview video, and app icon are the first visual signals.
- Icon clarity at 120×120px (iOS) and 192×192px (Play)
- Screenshot text readability and message hierarchy
- Video engagement (if submitted)
Localization Readiness (8 points)
If you're planning international growth, stores rank translated listings lower if they're obviously machine-generated.
- Language correctness in description
- Cultural relevance of screenshots
- Pricing strategy per region
Rating & Review Health (5 points)
App Store algorithms do inject ratings into ranking. A 4.2-star app ranks higher than a 3.8-star app in the same category.
- Recent review velocity
- Response rate to reviews
- Average sentiment drift
Version Release Cadence (3 points)
App stores reward active maintenance.
- Updates every 2–4 weeks = signal of a live app
- Longer gaps (3+ months) = drop in recency score
What Moves the Needle Fastest
From analyzing thousands of apps:
- Keyword in title — +15% visibility in 48 hours
- A/B testing screenshots — +8–12% in 2 weeks
- Fixing review response rate — +5–7% in 1 month
- Localizing for top markets — +20% in new regions
The Median App
The median app scores 18/30. Getting to 24+ puts you in the top 20% for your category.
