## Rating Impact on Conversion
| Rating Change | Conversion Impact |
| -------------------------- | --------------------------------------- |
| 3.0 to 4.0 stars | **+89%** |
| 4.0 to 4.5 stars | **+20-30%** |

| 0.4-star gap vs competitor | **~25% lost installs** from same search |
| 3-star vs 5-star app | **50% fewer conversions** for 3-star |
**Critical thresholds:**
- **4.0 stars** = minimum for Apple featuring, user trust, conversion viability
- **4.5+ stars** = optimal zone. Sweet spot: 4.1-4.9
- **5.0 stars** can look suspicious to users
- **Below 3.5** = sharp visibility drop on both stores
- **79% of users** check ratings before downloading
- **50% reject** apps below 3 stars
Sources: AppFollow, MobileAction, Sensor Tower, Troof.ai
## Preview Video Impact
**iOS:** +20-40% conversion lift (video autoplays on product page)
**Google Play:** Minimal lift (only ~6% of visitors tap to play)
- Autoplay introduced in iOS 11 caused **+47% conversion jump**
- Users who watch video are **2x more likely to install**
- Average watch time: **4-6.5 seconds** (first 5 seconds are critical)
- 50%+ of viewers watch to the end
**Takeaway:** Video is high-ROI on iOS, low-ROI on Google Play.

- Well-designed screenshots lift conversion **20-35%**
- A/B test winners see **10-25% improvement**
- **Optimal count:** 4-5 for utility apps, 5-6 for complex apps
- More than 6: diminishing returns, can cause decision paralysis
- Top 200 apps update screenshots **2-4 times/year**
- Top Google Play games update visuals **up to 8x/year**
- **57% of top games** A/B tested screenshots at least 2x in 2024

# ASO Scoring Criteria
Score each dimension 0-10 using the rubrics below.
**Apply brand maturity tier adjustments** from Phase 1.5 of the main skill.
---
## Brand Maturity Adjustments (apply to all dimensions)
Before scoring, determine the app's tier: **Dominant**, **Established**, or **Challenger**.
**Dominant apps (Instagram, Uber, Spotify, WhatsApp, Netflix):**
- Brand-only titles score 8+ (the brand IS the keyword)
- Lifestyle/brand screenshots score same as captioned UI screenshots
- Generic What's New at weekly+ cadence scores 8+
- Missing in-app events for utility apps is not a penalty
- Description scored on conversion quality only, not keyword presence
- Localization scored relative to actual market footprint
- Missing preview video is acceptable if brand awareness is near-universal
**Established apps (Duolingo, Strava, Notion, Calm, Cash App):**
- Brand-first titles with 1-2 keywords score normally
- Strategic description/visual choices get benefit of the doubt
- All other dimensions scored normally
**Challenger apps (most apps):**
- Scored strictly against textbook ASO — every character and feature matters
**Key principle:** Before docking points, ask: "Is this a mistake or a data-informed
choice by a team with more information than I have?"
---
## 1. Title & Subtitle (Weight: 20%)
**Challenger rubric:**
| Score | Criteria |
| ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 9-10 | Brand + high-value keyword in title, complementary keywords in subtitle, no word repetition across fields, near max character usage, instantly communicates app purpose |
| 7-8 | Good keyword presence, minor character waste (5+ unused chars), clear purpose |
| 5-6 | Has keywords but poor placement, some repetition between fields, purpose somewhat clear |
| 3-4 | Title is brand-only or generic, subtitle missing or weak, poor character usage |
| 1-2 | No keyword strategy, title doesn't communicate purpose, major character waste |
| 0 | Cannot assess (data unavailable) |
**Dominant/Established adjustment:** Brand-only titles (e.g., "Instagram") are
valid if the brand has high search volume. Score 8+ for Dominant apps where
brand recognition eliminates the need for generic keywords. Evaluate whether
unused characters represent waste or intentional simplicity.
**Check for:**
- Characters used vs limit (title: 30, subtitle/short desc: 30/80). "Near max" = within 3 chars of the limit (27+/30, 77+/80)
- Primary keyword in title
- Keyword duplication between title and subtitle
- Whether app purpose is immediately clear
- Unnecessary words (articles, prepositions) consuming space
- Special characters or claims ("#1", "best") that risk rejection (Apple)
---
## 2. Description (Weight: 15%)
### Apple App Store
| Score | Criteria |
| ----- | ------------------------------------------------------------------------------------------------------------------------------------------------------ |
| 9-10 | First 3 lines hook with clear value prop, structured with features/benefits/social proof/CTA, promotional text actively used, compelling and scannable |
| 7-8 | Good opening, decent structure, could improve scannability or CTA |
| 5-6 | Generic opening ("Welcome to..."), some structure, missing CTA or social proof |
| 3-4 | Wall of text, no clear value prop above fold, no promotional text |
| 1-2 | Minimal or boilerplate description, no effort |
| 0 | Cannot assess |
### Google Play
| Score | Criteria |
| ----- | -------------------------------------------------------------------------------------------------------------------------------------------- |
| 9-10 | Keywords in first 3 sentences, 2-3% natural density throughout, HTML formatting used, structured sections, strong CTA, keywords feel natural |
| 7-8 | Good keyword presence, some structure, density slightly off (1-2% or 3-4%) |
| 5-6 | Keywords present but sparse (<1%) or stuffed (>5%), weak structure |
| 3-4 | No keyword strategy visible, poor formatting, wall of text |
| 1-2 | Minimal description, no keywords, no structure |
| 0 | Cannot assess |
**Check for:**
- First 3 lines quality (visible before "Read More")
- Feature-benefit framing (not just feature lists)
- Social proof (downloads, awards, press mentions)
- Call to action
- Keyword density (Google Play only - count target keywords / total words)
- HTML formatting usage (Google Play)
- Promotional text presence and quality (Apple)
---
## 3. Visual Assets (Weight: 25%)
| Score | Criteria |
| ----- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
| 9-10 | 8-10 screenshots with clear messaging/captions, preview video present, screenshots tell a story in sequence, each communicates one benefit, icon is distinctive and memorable |
| 7-8 | 6-7 screenshots with captions, good icon, no video OR good video but some screenshot messaging unclear |
| 5-6 | 5+ screenshots but weak/no captions, basic icon, no video, screenshots are UI dumps |
| 3-4 | 3-4 screenshots, no captions, generic icon, no storytelling |
| 1-2 | Fewer than 3 screenshots, or screenshots are raw unedited UI, poor icon |
| 0 | Cannot assess |
**Check for:**
- Screenshot count (minimum 5, ideal 8-10)
- Caption/overlay text on screenshots (one message per screen, 5-7 words max)
- First 3 screenshots (highest conversion impact on Apple)
- Preview video presence and quality
- Icon distinctiveness (no text in icon, bold shapes, stands out)
- Feature graphic presence (Google Play - mandatory for featured placements)
- Screenshot storytelling flow (do they tell a coherent story?)
- Localized visual assets (for non-English markets)
- Caption keywords (Apple - indexed since June 2025)
---
## 4. Ratings & Reviews (Weight: 20%)
| Score | Criteria |
| ----- | ------------------------------------------------------------------------------------------------------ |

## Calculating Final Score
```
Final Score = (Title * 0.20) + (Description * 0.15) + (Visuals * 0.25)
+ (Ratings * 0.20) + (Metadata * 0.10) + (Conversion * 0.10)
Scale to 100: Final Score * 10
```
**Example:** Title: 7, Description: 6, Visuals: 8, Ratings: 9, Metadata: 5, Conversion: 7
```
(7 * 0.20) + (6 * 0.15) + (8 * 0.25) + (9 * 0.20) + (5 * 0.10) + (7 * 0.10)
= 1.4 + 0.9 + 2.0 + 1.8 + 0.5 + 0.7
= 7.3 → 73/100 → Grade: B
