# Payment Attribution Analysis

> Diagnoses payment rate anomalies and attributes payment changes to root causes by breaking down payment drivers (Revenue = Active × Rate × ARPPU), identifying key conversion nodes, and supporting multi-dimension analysis across channel, server, user segmentation, product node, activity/version, and time dimensions. Use when users need to diagnose payment rate anomalies, investigate revenue decline, or attribute payment changes to root causes.

---

## Language Policy

**CRITICAL**: Always respond in the user's language.
- If user writes in English → Respond in English
- If user writes in Chinese → Respond in Chinese
- Never translate the user's language; match their input language exactly

---

## Workflow

Multi-turn dialogue consultation, progressing through the following stages.
Execute "Stage Closing Guide" after completing each stage.

---

### Pre-Step 0: Context Check and Intent Confirmation

**Priority Check**: Whether the user's message is responding to another skill's question

| Context Scenario | User's Current Message | Judgment |
|-----------------|----------------------|----------|
| te-analysis asks "Which report type do you want?" | "Payment analysis" | ⛔ Intercept—this is a report name |
| te-analysis is configuring payment metrics | "Payment rate" | ⛔ Intercept—this is a metric selection |
| No other skill in progress, fresh conversation | "Payment rate dropped, what's the reason?" | ✅ Allow to start |

**Intent Confirmation**: If user description is vague (e.g., "payment issues"), first output introduction to confirm:

> 4. When did the change start? (Specific date or version)
> 5. Do you have a project ID? I can help query detailed data

---

Proceed to the next step after user confirmation.

---

### Stage 1: Problem Definition and Data Confirmation

**Objective**: Clarify the specific metric, time range, and magnitude of the payment change, and obtain traceable data through ae-cli.

#### 1.1 Collect Key Information

| Information | Description | Follow-up Approach |
|------------|-------------|-------------------|
| Core Metric | Payment rate / ARPU / ARPPU / Revenue / Paying users | "Which metric changed?" |
| Change Trend | Increase / Decrease / Fluctuation | "Did it get better or worse?" |
| Comparison Baseline | What to compare against (yesterday/last week/target/industry) | "What are you comparing against?" |
| Change Magnitude | Specific numerical change | "How much did it change? (e.g., from 5% to 3%)" |
| Anomaly Start Time | When the change started, comparison period | "From which date/version?" |
| Game Type | SLG/MMO/Card/Casual, etc. | "What type of game is it?" |
| Project ID | Used to query TE data source | "Please provide project ID, I'll help you query data" |
| Related Events | Version update / Activity / Operations adjustment | "Were there any version updates or activities during this time?" |

#### 1.2 Variant Routing: Payment Metric Breakdown Framework

Based on the user's stated metric, select the appropriate diagnostic variant:

**Variant A: Payment Rate Anomaly** — Triggered when user says "payment rate dropped / is anomalous / below expectations"

```
Payment Rate = Payers / Active Users × 100%

Focus: Numerator/denominator definition, data accuracy, rate-level change
```

**Variant B: Revenue Attribution** — Triggered when user says "what drove the payment change / revenue declined / ARPPU changed"

```
Revenue = Paying Users × ARPPU
        = Active Users × Payment Rate × ARPPU

ARPPU = Total Revenue / Paying Users

Focus: Revenue decomposition, which factor (Active, Rate, ARPPU) drove the change
```

**Three-Scenario Attribution Logic** (shared across both variants):

```
Scenario 1: Active users unchanged, paying users decreased
→ Check: Payment conversion funnel issues

Scenario 2: Active users increased, paying users unchanged
→ Check: New user quality decline / non-paying users flooding in

Scenario 3: Active users decreased, paying users decreased more
→ Check: Core paying users churned + insufficient acquisition
```

#### 1.3 Data Source Retrieval (Three Paths)

**Execution Logic**: Try Priority 1→2→3 in order, stop when data source is found.

---

**Priority 1: Find Existing Dashboard/Report**

```
[Applicable Scenario]
- User has provided project ID
- Project already has payment rate related dashboard or report

[Execution Steps]
1. Run `analysis report list` and `analysis dashboard list` with payment-rate keywords
2. Follow fuzzy-search fallback before concluding that no asset exists
3. If a matching report is found, use `analysis report get` and `analysis report-data run`
4. If a matching dashboard is found, use `analysis dashboard get` and `analysis dashboard-report-data run`
5. Generate and preserve the required request ID before each query
6. If no matching asset is found → Go to Priority 2
```

---

**Priority 2: Underlying Metrics Query**

```
[Applicable Scenario]
- Priority 1 found no relevant dashboard
- Project has payment rate related metrics or events

[Execution Steps]
1. Express active-user and payer metrics in an AI-facing event definition
2. Include the confirmed time range and any requested group/filter
3. Run `analysis adhoc run --model-type event --definition '<json>'`
4. Inspect `meta.resolved`, `meta.warnings`, and the effective query scope
5. If compilation needs clarification, select an exact returned candidate or ask the user
```

---

**Priority 3: Save a Verified Analysis (Requires Confirmation)**

```
[Applicable Scenario]
- No matching saved asset exists
- Priority 2 produced a successful, verified ad-hoc query
- The user explicitly asks to persist the analysis

[Execution Steps]
1. Explain the target project, report/dashboard names, metric definition, and write impact
2. Obtain explicit user confirmation
3. Reuse the verified AI-facing definition with `analysis report create`
4. Create the dashboard with `analysis dashboard create --initial-report-id <report_id>`
5. Complete the report and dashboard link loop with `analysis-meta asset url-get`

[Notes]
- Do not create assets automatically
- If a write fails, report the structured error and retain the successful query result
- Return a resource link after every successful report/dashboard write
```

---

#### 1.4 Data Accuracy Check

**Execute the following checks after obtaining data**:

| Check Item | Possible Issue | Verification Method |
|-----------|---------------|-------------------|
| Denominator definition | Active user count definition inconsistent | Confirm if it's DAU or startup count |
| Numerator definition | Payer count calculation error | Confirm if deduplicated, if free orders included |
| Time definition | Payment time vs order creation time | Confirm statistics time definition |
| Data delay | Partial data not yet loaded | Check for delayed reporting (compare today with same period yesterday) |
| Tracking anomaly | Payment event missing/duplicate reporting | Check event reporting logs (call search_events to verify event configuration) |

**Health Check Script**:

> Before diving deep into analysis, let's confirm data accuracy:
>
> 1. **Payment Rate Formula Confirmation**: Is your calculated payment rate `Payers / Active Users`?
> 2. **Time Definition Confirmation**: Is payer count based on payment time or order creation time?
> 3. **Data Completeness**: Is there any recent data delay or reporting anomaly?
>
> If data anomaly detected (e.g., today's data significantly low), I will promptly alert you.

#### 1.5 Industry Benchmarks and Lifecycle Reference

**Game Genre Payment Rate Benchmarks**:

| Game Genre | Payment Rate Benchmark | ARPPU Benchmark | Notes |
|-----------|----------------------|----------------|-------|
| Casual Games | 1.5%-3% | $5-$15 | Large user base, low payment rate |
| Card Games | 3%-8% | $10-$40 | Collection/progression-driven payments |
| SLG | 5%-12% | $30-$150 | High Spender contribution |
| MMO | 4%-10% | $15-$75 | Social + progression-driven |
| Idle Games | 2%-5% | $5-$25 | Light payments dominant |
| Board | 5%-10% | — | Strong user payment awareness |
| Simulation | 2%-4% | — | Medium-low payment rate |

Note: Benchmarks vary significantly with game lifecycle stage; evaluate with product phase.

**Product Lifecycle and Payment Metrics**:

| Stage | Payment Rate Characteristics | ARPPU Characteristics | Focus Areas |
|------|------------------------------|----------------------|-------------|
| Acquisition | Lower (mixed user quality) | Lower | Acquisition + Onboarding conversion |
| Growth | Rapid increase | Increasing | Payment point design |
| Mature | Stable | Stable | High Spender retention + activities |
| Decline | Declining | Fluctuating | Recall + Win-back |

---

### Stage 2: Dimension Breakdown Analysis

**Objective**: Through dimension drill-down, locate the main contributing dimension of the payment change.

#### 2.1 Data Retrieval Strategy

**If Stage 1 obtained data via ae-cli**:
- Directly use obtained payment rate trend data
- Rebuild and query one requested dimension at a time

**If Stage 1 didn't obtain data (user directly entered values)**:
- Logical deduction based on user-provided information
- Provide possible causes and investigation recommendations for each dimension

#### 2.2 Shared Output Format Template

All dimension analyses use the following format (columns may vary by dimension):

```
[Dimension Name Payment Analysis]

| [Dimension] | Active Users | Paying Users | Payment Rate | ARPPU | Change | Key Finding |
|---|---|---|---|---|---|---|
| ... | ... | ... | ... | ... | ... | ... |

[Key Findings]
- [Primary finding]
- [Secondary finding]
- Problem focus: [Specific area]
```

#### 2.3 Dimension Breakdown Framework

Investigate in the following priority order (**only query one dimension at a time, wait for confirmation after each**):

**Priority 1: Channel Dimension**

```
[Investigation Logic]
- Compare payment rates across channels: Find the channel with lowest payment rate
- Channel traffic structure change: Did low-payment channel proportion increase?
- Channel quality change: Did old channel payment rate drop?

[ae-cli Data Retrieval]
- Add the channel group to the AI-facing definition
- Execute `analysis adhoc run --model-type event --definition '<json>'`
```

**Priority 2: Server/Region Dimension**

```
[Investigation Logic]
- New server vs old server: New server payment rate usually lower
- Server merge impact: Payment rate fluctuates after merge
- Per-server payment rate: Payment rate distribution across servers

[ae-cli Data Retrieval]
- Add the server group to the AI-facing definition
- Execute `analysis adhoc run --model-type event --definition '<json>'`
```

**Priority 3: User Segmentation Dimension**

```
[Investigation Logic]
1. New Users vs. Returning Users
   - New user payment rate declined → Onboarding / first purchase design issue
   - Returning user payment rate declined → Content depleted / churn warning

2. Payment Tier Breakdown
   - Low Spender (<$5 per transaction): Price sensitive, heavily impacted by pricing
   - Mid Spender ($5-$50 per transaction): Value-driven, impacted by promotions
   - High Spender (>$50 per transaction): Status-driven, impacted by service/scarcity

3. Retention Days Breakdown
   - Day 1 payment decline → First purchase guide / starter pack issue
   - Day 7 payment decline → Mid-term content / payment point design issue
   - Day 30+ payment decline → Long-term progression / insufficient social drivers

[ae-cli Data Retrieval]
- Add the user-tier or registration-age group/filter to the AI-facing definition
- Execute `analysis adhoc run --model-type event --definition '<json>'`
```

**Priority 4: Time Dimension**

```
[Investigation Logic]
1. Daily Trend
   - Single-day plunge → Check if there was an anomaly that day (maintenance/Bug/config error)
   - Sustained decline → Systemic issue (user quality/product defect)
   - Periodic fluctuation → Weekend effect/activity impact

2. Hourly Trend
   - Certain hours plunge → Check operations actions/server status during those hours
   - Golden hours decline → Core user active hours payment decline

3. Pre/Post Version Comparison
   - Decline after version → Version content impacted payment experience
   - Increase after version → Version payment design took effect

[ae-cli Data Retrieval]
- Adjust `time_range` and `time_particle_size` in the AI-facing definition
- Execute `analysis adhoc run --model-type event --definition '<json>'`
```

**Priority 5: Product Node / Payment Point Dimension**

```
[Investigation Logic]
1. Level/Chapter Progress
   - Certain level failure rate spiked → Difficulty design unreasonable
   - Certain level churn rate high → Pain points causing user abandonment

2. Payment Point Conversion
   - Bundle view→purchase conversion rate declined → Bundle attractiveness/pricing issue
   - Shop visit→payment conversion rate declined → Product structure/price range issue

3. Payment Point Penetration Rate
   - First purchase / Monthly card / Gift pack / Direct charge penetration rate changes
   - New payment point vs old payment point performance

4. Feature Usage Rate
   - Core payment feature usage declined → Feature entry/guidance issue
   - Old feature payments declined after new feature launched → Payment point migration/cannibalization

[ae-cli Data Retrieval]
- Add the level or payment-point group to the AI-facing definition
- Execute `analysis adhoc run --model-type event --definition '<json>'`
- Inspect compiler candidates instead of guessing metadata names
```

**Priority 6: Activity/Version Dimension**

```
[Investigation Logic]
1. Pre/Post Activity Comparison
   - Payment declined after activity → Payment demand exhausted / activity dependency
   - Payment increased after activity → Activity drove new paying users

2. Activity Type Comparison
   - Recharge-type activity → Drives payments from existing high spenders
   - First-purchase-type activity → Drives new user conversion
   - Limited-time discount → Price-sensitive user conversion

3. Version Content Impact
   - New payment point launched → Payment rate short-term increase
   - Numeric adjustments → Payment structure changes
   - Gameplay updates → User activity→payment funnel changes

4. Version Bug Impact
   - Payment SDK anomaly → Payment conversion crash
   - Level Bug → User pain point churn

[ae-cli Data Retrieval]
- Add activity/version filters and groups to the AI-facing definition
- Execute `analysis adhoc run --model-type event --definition '<json>'`
```

#### 2.4 Main Cause Location Formula

**Payment Rate Change Attribution**:

```
Overall payment rate change = Σ(Each dimension payment rate change × That dimension DAU proportion)
                            + Σ(Each dimension DAU proportion change × That dimension baseline payment rate)

Simplified understanding:
- Structure effect: Low-payment group proportion increased → Pulls overall down
- Intrinsic effect: Each group's own payment rate dropped → Overall decline
```

### Stage 3: Root Cause Diagnosis and Recommendations

**Objective**: Based on dimension breakdown results, provide root cause diagnosis and actionable recommendations.

#### 3.1 Unified Root Cause Framework

| Root Cause Category | Symptoms | Possible Causes | Optimization Direction |
|---|---|---|---|
| A. Channel Quality | Certain channel payment rate continuously declining; New channel significantly below expectations | Channel user quality declining, fake traffic, channel-user mismatch | Communicate quality feedback, adjust bidding, reduce low-quality channels |
| B. New User Payment | New user payment rate lower than existing users; New user payment rate continuously declining | Onboarding too complicated, first purchase pack not attractive, buying materials over-promising | Simplify onboarding, optimize first purchase pack, A/B test new player gift pack |
| C. Server/Region Effect | New server payment rate significantly lower; New server proportion increase pulls overall down | New server users in experience period, high server opening frequency | New server exclusive first purchase event, control server opening rhythm, server merge strategy |
| D. Product Node / Payment Point | Level failure rate surge; Payment point penetration rate dropped; Bundle conversion rate declined | Difficulty design unreasonable, value proposition issue, exposure insufficient, pricing unreasonable | Adjust level difficulty, optimize reward content, add exposure entrance, pricing A/B test |
| E. Version / Activity Impact | Payment rate dropped after version update; Payment rate dropped after activity ended | Version Bug, payment point adjustments, activity demand exhausted, activity dependency | Rollback or hotfix, activity rhythm planning, post-activity follow-through design |
| F. Returning User / High Spender | Returning user payment rate declined; High Spender churn | Content depleted, High Spender care inadequate, economy unbalanced, insufficient social drivers | Accelerate new content, High Spender exclusive activities, strengthen social gameplay |
| G. External Factors | Channel quality changes, competitor activity, market environment changes | Channel user quality changes, competitor launches, market shifts | Channel strategy adjustment, competitive analysis, market monitoring |

#### 3.2 Key Scenario Deep-Dives

**Scenario 1: New User Payment Rate Declined**

```
[Root Cause Diagnosis]
Possible causes:
1. Onboarding too complicated, users didn't experience core fun
2. First purchase pack attractiveness insufficient / pricing too high
3. Opening design unappealing, mass churn on Day 2-3

## Internal Best Practices

### Payment Rate Analysis Three-Dimensional Framework

| Dimension | Analysis Points | Diagnostic Questions |
|-----------|---------------|-------------------|
| User Structure | New/existing user proportion, High/Mid/Low Spender distribution | Did new user proportion increase too much pulling overall down? |
| Payment Scenarios | First purchase/Monthly card/Gift pack/Direct charge penetration rate | Which payment point had the most penetration rate drop? |
| Reach Timing | New player guide nodes, progression bottlenecks, gameplay frustration points | Did payment prompts appear at the right timing? |

### User Tier Strategy

| User Tier | Characteristics | Payment Rate Benchmark | Optimization Strategy |
|-----------|---------------|---------------------|-------------------|
| High Spender | Historical cumulative payment ≥$150 | Monthly payment rate 60%-80% | Exclusive customer service, limited gift pack, VIP privileges |
| Mid Spender | Historical cumulative payment $15-$150 | Monthly payment rate 30%-50% | Monthly card/pass, growth gift pack, value tier |
| Low Spender | Historical cumulative payment <$15 | Monthly payment rate 10%-25% | First purchase double, $0.99 gift pack, low-threshold promotion |

**Payment Ability Evaluation Time Window**: Based on highest single payment in past 7-14 days to determine user tier.

### Scenario-Based Pricing Timing

| Scenario Type | Trigger Timing | Recommended Gift Pack Type | Value Benchmark |
|--------------|---------------|--------------------------|---------------|
| New Player Guide Period | 1-3 days after registration | First purchase gift pack, new player gift pack | 3-5x (Low tier) |
| Progression Bottleneck | When core materials insufficient | Material gift pack, speed-up gift pack | 2.5-4x (Mid tier) |
| Gameplay Frustration | After PVP losing streak/level stuck | Combat power improvement gift pack, limited discount | 2-3x (High tier) |
| Social Driven | Before guild battle/team formation | Team gift pack, competitive gift pack | 2.5-4x (Mid tier) |

### Price Anchoring Principles

| Tier | Value Range | Price Interval Principle | Goal |
|------|-----------|------------------------|------|
| Low tier | 3-5x | Interval with mid tier ≥2x | Low Spender penetration, payment ice-breaking |
| Mid tier | 2.5-4x | Interval with low/high tier 1.5-2x | Mid Spender main, revenue stability |
| High tier | 2-3x | Interval with mid tier ≥1.5x | High Spender exclusive, ARPPU improvement |

**Note**: Value = Item value / price, higher value = better user perception of value.

## Error Handling

**When encountering the following situations**:

1. **User cannot provide metric value**:
   > For more accurate diagnosis, recommend first querying current payment rate data.
   > You can provide a project ID, and I will verify the project and query it through ae-cli;
   > Or through [Analytics - Event Analysis] select payment event and startup event to calculate.

2. **ae-cli call fails (no permission/project ID error)**:
   > Cannot access project data, possible reasons:
   > - Project ID incorrect
   > - You don't have access permission to this project
   > - ae-cli authentication or service routing is unavailable
   >
   > Recommendations:
   > - Confirm project ID (check in TE system project list)
   > - Confirm you're logged into TE system and have access permission
   > - Or, you can directly tell me the payment rate value, I can analyze directly

3. **ae-cli returns an empty result (no matching dashboard/report)**:
   > No payment rate related dashboard or metrics found.
   >
   > Possible reasons:
   > - Payment rate dashboard hasn't been created in project
   > - Event name not pay/app_start (e.g., other custom events used)
   >
   > Recommendations:
   > - You can provide event name, I'll try querying with custom event
   > - Or directly tell me the payment rate value, I can analyze directly

4. **Data accuracy in doubt**:
   > Data anomaly detected (e.g., [specific issue]), recommend first investigating data reporting issues.
   > Investigation steps: [Step 1, 2, 3...]

5. **Insufficient payment data**:
   > Sample <50 or period <7 days → Recommend expanding period or providing more data.

6. **Need to query specific data**:
   > I can try querying data through ae-cli, but I need you to provide:
   > - Project ID
   > - Data dimensions to view (e.g., "by channel", "by server")
   >
   > If cannot query, I will tell you analysis method and investigation approach.

7. **Issue beyond payment attribution scope** (e.g., LTV/ARPU dropped):
   > This issue involves [LTV/ARPU] metrics, recommend using corresponding analysis skill.
   > I can help transfer or tell you investigation approach.

## Quick Reference Card

### Payment Rate Breakdown Formulas

```
Payment Rate = Paying Users ÷ Active Users
Revenue = Paying Users × ARPPU
        = Active Users × Payment Rate × ARPPU
```

### Three Scenarios of Payment Rate Decline

```
Scenario 1: Active users unchanged, paying users decreased → Check payment conversion
Scenario 2: Active users increased, paying users unchanged → Check new user quality
Scenario 3: Active users decreased, paying users decreased more → Check core paying users churn
```

### Main Cause Location Formula

```
Structure effect: Low-payment group proportion increased → Pulls overall down
Intrinsic effect: Each group's own payment rate dropped → Overall decline
```

### Investigation Priority

```
1. Data accuracy → 2. Channel → 3. Server → 4. User segmentation → 5. Time → 6. Product node → 7. Activity/Version
```

### Root Cause Quick Reference

```
A. Channel quality decline → Adjust targeting strategy
B. New user payment rate low → Optimize onboarding / first purchase
C. New server proportion high → New server exclusive activities
D. Product node / payment point issues → Optimize rewards / pricing / difficulty
E. Post-version / post-activity decline → Rollback or hotfix / activity rhythm planning
F. Returning user / High Spender decline → Content updates / High Spender care
G. External factors → Channel strategy / competitive analysis

### ae-cli Call Priority

```
Priority 1: Search and query an existing report/dashboard
Priority 2: AI-facing event definition → analysis adhoc run
Priority 3: Persist only after a successful query and explicit user confirmation
```

### Required ae-cli Context

```
projectId: Project unique identifier (required, ask directly if user cannot provide)
dashboardId: Dashboard ID (verify through analysis dashboard list when unknown)
reportIds: Report ID list (obtain from analysis report list or analysis dashboard get)
Time range: yyyy-MM-dd format, default last 7 days
definition: AI-facing event intent; never raw QP or a frontend DTO
requestId: Preserve the gateway request ID generated or supplied for query diagnostics
```
