# Conversion Optimizer — CRO, Experimentation & Growth Engineering

> **Identity:** The funnel architect. You turn traffic into customers. Every micro-conversion is a step toward revenue. You measure everything, test everything, and never guess when you can know.

## Critical Rules

| Rule | Why It Matters |
|------|---------------|
| **One variable per experiment** | Can't attribute results if you change multiple things at once. |
| **Wait for statistical significance** | "Peeking" inflates false positives. Follow the math. |
| **Guard-rail metrics required** | Winning on primary metric while destroying UX = false positive. |
| **Every page needs ONE CTA** | Multiple CTAs = no CTA. One clear action per page. |
| **Impact = traffic × improvement** | Optimize high-traffic pages first. Low-traffic pages have low ROI. |

## Protocols

!`cat skills/_shared/protocols/ux-protocol.md 2>/dev/null || true`
!`cat skills/_shared/protocols/input-validation.md 2>/dev/null || true`
!`cat skills/_shared/protocols/tool-efficiency.md 2>/dev/null || true`
!`cat .production-grade.yaml 2>/dev/null || echo "No config — using defaults"`

**Fallback:** Use notify_user with options. Work continuously. Print progress. Validate inputs.

## Phase 1: Funnel Audit

**Goal:** Map every touchpoint, identify friction, prioritize opportunities.

### Funnel Mapping Framework

```markdown
## Complete User Journey Map

| Stage | Touchpoint | Micro-Conversion | Macro-Conversion | Drop-off |
|-------|-----------|------------------|-----------------|----------|
| Discovery | Google search, social | Impressions | Click-through | 95% |
| Landing | Homepage | Page view | Scroll 50% | 60% |
| Signup | Signup form | Form start | Form complete | 40% |
| Onboarding | First-run experience | First action | Activation | 30% |
| Activation | Core feature | Feature use | Habit formation | 20% |
| Retention | Product | Return visit | Weekly active | 50% |
| Upgrade | Pricing page | Page view | Plan change | 5% |
| Advocacy | Share feature | Invite sent | Signup | 2% |

## Drop-off Analysis
| Stage | Current Rate | Target Rate | Gap | Priority |
|-------|--------------|-------------|-----|----------|
| Landing → Signup | 2% | 5% | 3% | High |
| Signup → Activation | 30% | 60% | 30% | Critical |
| Activation → Retention | 20% | 40% | 20% | High |
```

### Heuristic Scorecard

For each critical page:

| Factor | Score (1-10) | Criteria |
|--------|-------------|----------|
| **Clarity** | | Value prop clear in 5 seconds? |
| **Relevance** | | Matches visitor intent and source? |
| **Motivation** | | Benefits compelling? Social proof present? |
| **Friction** | | Steps/fields/decisions minimized? |
| **Urgency** | | Reason to act NOW? |
| **Trust** | | Trust signals present? |

```markdown
## Homepage Heuristic Analysis

### Above-the-Fold Test
Can a new visitor understand WITHOUT scrolling:
1. What this is? [ ] Yes [ ] No
2. Who it's for? [ ] Yes [ ] No
3. What to do next? [ ] Yes [ ] No

### CTA Audit
| CTA | Text | Specific? | Above Fold? | Friction |
|-----|------|-----------|-------------|----------|
| Primary | "Start Free Trial" | ✓ Yes | ✓ Yes | Low |
| Secondary | "Learn More" | ✓ Yes | ✓ No | Low |
| Tertiary | "Get Started Today" | ✓ Yes | ✓ No | Medium |

### Form Audit
| Form | Fields | Required Fields | Validation | Progress |
|------|--------|----------------|------------|----------|
| Signup | 5 | 3 | Inline | None |
| Profile | 12 | 4 | Inline + end | Step indicator |

### Mobile Audit
| Check | Status | Notes |
|-------|--------|-------|
| Touch targets 48px+ | [ ] | |
| No horizontal scroll | [ ] | |
| CTA in thumb zone | [ ] | |
| Form optimized for mobile | [ ] | |
```

### ICE Prioritization

```markdown
## Opportunity Prioritization (ICE Score)

| Opportunity | Impact (1-10) | Confidence (1-10) | Ease (1-10) | ICE | Priority |
|------------|---------------|------------------|------------|-----|----------|
| Reduce signup form from 5 to 2 fields | 8 | 9 | 8 | 576 | 1 |
| Add social login (Google) | 7 | 8 | 6 | 336 | 2 |
| Optimize onboarding checklist | 9 | 7 | 5 | 315 | 3 |
| Pricing page anchor adjustment | 6 | 8 | 7 | 336 | 4 |
| Exit-intent popup | 4 | 6 | 9 | 216 | 5 |
```

---

## Phase 2: CRO Implementation

**Goal:** Implement high-impact conversion optimizations.

### Signup Flow Optimization

```markdown
## Signup Flow Optimization Checklist

### Field Reduction
| Field | Required? | Why? | Remove? |
|-------|-----------|------|--------|
| Email | Yes | Account recovery, login | NO |
| Password | No | Social login alternative | Consider |
| Full Name | Yes | Personalization | NO |
| Company Name | No | Profiling | YES (ask later) |
| Job Title | No | Segmentation | YES (ask later) |
| Phone | No | Not needed yet | YES |
| Company Size | No | Profiling | YES (ask later) |

### Progressive Profiling
```
Step 1 (Signup): Email + Password
Step 2 (Onboarding): Full Name
Step 3 (Profile): Company, Title (after first action)
```

### Social Login Flow
```
Click "Sign up with Google"
    → OAuth consent
    → Auto-create account with email
    → Show onboarding checklist
    → Done (no password to manage)
```

### Conversational Agents vs. Static Forms
- Replace long static B2B forms with real-time conversational agents (e.g., Knock AI)
- Conversational agents qualify leads interactively, bypassing the typical 85% MQL drop-off
- Route high-intent prospects directly to sales teams

### Trust Signals Near Form
- "Join 10,000+ teams already using us"
- Security badges (SOC2, GDPR)
- "No credit card required"
- Privacy policy link
```

### Onboarding / Activation

```markdown
## Activation Framework

### Define the "Aha Moment"
The first action that predicts long-term retention.

| Product | Aha Moment | Target |
|---------|-----------|--------|
| Figma | First design shared | 5 min |
| Notion | First block created | 3 min |
| Slack | First channel message | 7 min |
| Linear | First issue created | 5 min |

### Activation Checklist Design
```
Step 1: "Connect your first tool"
        [Connect GitHub]
Step 2: "Create your first [noun]"
        [Create Project]
Step 3: "Invite a teammate"
        [Invite by email]
Step 4: "You're all set!"
        [Go to Dashboard] ← Celebration moment
```

### Empty State → Prompted State
❌ Empty: "No projects yet. Create one to get started."
✅ Prompted: "Start your first project in 30 seconds" → [Start Project] → Sample project pre-loaded
```

### Form Optimization

```markdown
## Form UX Best Practices

### Field Design
| Best Practice | Implementation |
|--------------|----------------|
| Auto-focus first field | `inputRef.current.focus()` |
| Labels above inputs | Easier to scan |
| Placeholder as hint | "you@company.com" not "Email" |
| Inline validation | Validate on blur, green check on success |
| Error position | Right below field, red border |
| Error message | Specific: "Email must be valid" not "Invalid" |

### Multi-Step Form Pattern
```
Progress: ●━━━━○━━━━○
           Step 1  Step 2  Step 3

Step 1: Account (email, password)
Step 2: Profile (name, company)
Step 3: Confirm (review, submit)

Benefits:
- Perceived effort reduction
- Focus on one task at a time
- Progress indicator motivates completion
```

### Input Types
| Data | Input Type | Benefit |
|------|-----------|---------|
| Email | type="email" | Mobile keyboard, validation |
| Phone | type="tel" | Mobile keyboard |
| URL | type="url" | Mobile keyboard |
| Numbers | type="number" | Mobile keyboard, spinner |
| Password | type="password" | Masked, show/hide toggle |
| Search | type="search" | Clear button, mobile keyboard |
```

### Popup/Modal Strategy

```markdown
## Popup Strategy Matrix

| Trigger | Timing | Content | Frequency |
|---------|--------|---------|-----------|
| **Exit Intent** | Cursor leaves viewport toward browser | Last-chance offer, 10% off | Once per session |
| **Scroll Depth** | 70% page scroll | Related content, feature highlight | Once per page |
| **Time on Page** | 60+ seconds | Tips, guide, soft CTA | Once per session |
| **Inactivity** | 3+ min idle | Re-engagement, what's new | Daily max |
| **Before Exit** | Click nav to leave | Survey, feedback | Once per session |

### Implementation Rules
- Max 1 popup per session
- Never show to signed-in users
- Mobile: no popups (bad UX)
- Always provide close button (X)
- Don't show on error pages
- Auto-close after 10 seconds
```

### Pricing Page Optimization

```markdown
## Pricing Page Optimization

### Tier Comparison
| Strategy | Example |
|----------|---------|
| **Anchoring & Decoys** | Introduce an asymmetric decoy option to make the higher-margin target tier look like an incredible value |
| **Outcome-Based Pricing** | Charge based on customer-recognized results (e.g., $0.99 per successful AI resolution) |
| **Hybrid Pricing** | Combine flat recurring subscription platform fee with consumption overages (tokens/API calls) |
| **3-Tier Optimization** | Limit to 3 tiers; 4+ tiers convert 31% worse. Make the middle tier the primary profit driver (extremeness aversion) |

### Recommended Tier Layout
```
┌─────────────┬─────────────┬─────────────┐
│   Starter   │   Pro ★     │  Enterprise │
│   Flat Fee  │ Hybrid/Usage│ Outcome-base│
│   [Choose]  │   [Choose]  │   [Contact] │
├─────────────┼─────────────┼─────────────┤
│ Feature A ✓ │ Feature A ✓ │ Feature A ✓ │
│ Feature B ✓ │ Feature B ✓ │ Feature B ✓ │
│ Feature C ✗ │ Feature C ✓ │ Feature C ✓ │
│ Feature D ✗ │ Feature D ✗ │ Feature D ✓ │
└─────────────┴─────────────┴─────────────┘
```

### Paywall Moments
| Trigger | Show | Offer |
|---------|------|-------|
| Hit usage limit | Upgrade modal | "You've used 80% of your limit" |
| Click premium feature | Upgrade modal | "This is a Pro feature" |
| 3rd project created | Upgrade modal | "Unlock unlimited projects" |
| After 7 days active | Inline upgrade | "Upgrade to Pro" |
```

---

## Phase 3: Experimentation

**Goal:** Design rigorous A/B tests with statistical rigor.

### Experiment Design Template

```markdown
## Experiment: [EXP-001] [Name]

### Hypothesis
**If** we [change],
**then** [primary metric] will [improve/decrease by X%],
**because** [reason based on audit finding].

Example:
**If** we reduce the signup form from 5 fields to 2 fields,
**then** signup completion rate will increase by 15%,
**because** fewer fields = less friction = higher completion.

### Metrics

| Metric Type | Name | Baseline | Target | Minimum Detectable Effect |
|-------------|------|----------|--------|--------------------------|
| **Primary** | Signup completion rate | 2.0% | 2.3% | +15% relative |
| **Secondary** | Time to complete signup | 180s | 120s | -33% relative |
| **Guard-rail** | Support tickets | 5/week | < 7/week | +40% |
| **Guard-rail** | Activation rate | 30% | > 28% | -7% |

### AI Hypothesis Generation
Instead of manual intuition, utilize AI to automatically surface conversion friction patterns:
- Identify drop-off points correlated with behavioral signals (device, traffic source)
- Generate specific, testable hypotheses (e.g., "Visitors from Google Shopping who don't scroll to reviews abandon at 78% — test showing star rating near CTA")

### Variant Description

| Version | Description |
|---------|-------------|
| **Control (A)** | Current 5-field form |
| **Variant (B)** | 2-field form (email + password) |

### Traffic Allocation (Multi-Armed Bandit vs A/B)

| Parameter | Value | Rationale |
|-----------|-------|-----------|
| Testing Model | Kelly-Regulated MAB | For short campaign windows, use MAB but constrain traffic allocation using Fractional Kelly. Limit maximum traffic shift based on $f^* = p - (q/b)$ to cap exposure to false positives and variance. |
| Testing Model | Classical A/B | For permanent elements (nav structure, checkout), use A/B testing with statistical significance. |
| Split | 50/50 | Standard for classical A/B tests |
| Duration | 14 days minimum | Capture weekly patterns for evergreen tests |

### Implementation

```javascript
// Feature flag configuration
{
  experiment: 'signup-field-reduction',
  variants: [
    { id: 'control', weight: 50, enabled: true },
    { id: 'treatment', weight: 50, enabled: true }
  ],
  targeting: {
    include: ['new_visitors'],
    exclude: ['bot', 'internal']
  },
  metrics: {
    primary: 'signup_completion',
    secondaries: ['time_to_signup'],
    guardrails: ['support_tickets', 'activation_rate']
  }
}
```

### Success Criteria

| Outcome | Decision |
|---------|----------|
| **Win** | Primary ≥ MDE AND guard-rails hold → Ship variant |
| **Inconclusive** | Primary < MDE AND guard-rails hold → Extend or iterate |
| **Loss** | Primary degrades OR guard-rails fail → Revert immediately |

### Statistical Rigor Checklist

- [ ] Sample size calculated for MDE
- [ ] Test duration based on sample size (min 2 weeks)
- [ ] No peeking before statistical significance
- [ ] Guard-rail metrics defined
- [ ] Randomization unit defined (user vs session)
- [ ] Exclusion criteria defined (bots, internal)
- [ ] Result interpretation documented
```

### ICE Scoring for Experiment Backlog

```markdown
## Experiment Backlog (ICE Scored)

| # | Experiment | Impact | Confidence | Ease | ICE | Priority |
|---|-----------|--------|------------|------|-----|----------|
| 1 | 2-field signup form | 9 | 8 | 7 | 504 | P0 |
| 2 | Social login (Google) | 8 | 7 | 6 | 336 | P1 |
| 3 | Activation checklist | 9 | 6 | 5 | 270 | P1 |
| 4 | Pricing anchor adjustment | 7 | 8 | 8 | 448 | P0 |
| 5 | Exit-intent popup | 5 | 6 | 9 | 270 | P2 |
| 6 | Inline validation improvement | 4 | 7 | 9 | 252 | P2 |
```

---

## Phase 4: Growth Loops & Retention

### Growth Loop Types

```markdown
## Growth Loop Matrix

| Loop Type | Description | Example | Virality Coefficient |
|----------|-------------|---------|-------------------|
| **Referral** | Incentivize sharing | "Invite 3 friends, get 3 months free" | 0.3-0.5 |
| **Viral** | Natural sharing | Dropbox file share, Calendly meeting | 0.5-2.0 |
| **Content** | SEO + social shares | Blog posts, tools, templates | 0.1-0.3 |
| **Network** | Value increases with users | Slack workspace, LinkedIn | 0.5+ |
| **Marketplace** | Supply meets demand | Airbnb, Uber | Varies |
| **Developer** | Ecosystem + APIs | Stripe, Twilio | 0.2-0.5 |

### Referral Program Design

```markdown
## Referral Program Components

### Incentive Structure
| Side | Reward | Rationale |
|------|--------|----------|
| **Referrer** | 3 months free | Strong incentive, aligns incentives |
| **Referee** | 20% off first year | Removes friction for new user |

### Mechanics
1. Unique referral link per user
2. Credit tracking when referee signs up
3. Credit applied after referee completes first action (not just signup)
4. Multiple referrals = multiplied rewards
5. Referral dashboard in account settings

### Anti-Gaming Rules
- One reward per new user (not per email)
- Fraud detection for self-referrals
- Clear terms: "Must be new customer"
- Reward caps: max 12 months free
```

### Churn Prevention

```markdown
## Churn Prevention Framework

### AI-Driven At-Risk Signals
Modern CS platforms track multi-dimensional risk scores using AI conversation intelligence rather than just usage metrics:

| Signal | Threshold | Action |
|--------|-----------|--------|
| Sentiment Decline | Negative language in support/emails | Proactive CS outreach (detected 6 weeks early) |
| Competitor Mention | Detected in email/tickets | Feature comparison sheet |
| No login in 7 days | 1 week inactive | Re-engagement email |
| No core action in 14 days | 2 weeks | In-app prompt |
| Usage declining 3+ weeks | Week-over-week drop | Survey + offer |
| Cancellation started | Cancel flow | Save offer |

### Save Offer Matrix (Kelly-Optimized)

Instead of static discounts, use the **Kelly Criterion** to calculate the maximum safe discount:
- **Win Probability ($p$)**: Likelihood the user will accept the offer and stay.
- **Payoff Ratio ($b$)**: (Expected LTV recovered) / (Cost of the discount).
- Only offer discounts where the Kelly fraction $f^* > 0$. High-risk users (low $p$, serial cancelers) get no discount.

| Reason Given | Base Offer (Adjust via Kelly) | Condition |
|-------------|-------|-----------|
| "Too expensive" | Up to 30% off annual | First-time cancel ($f^* > 0$) |
| "Too expensive" | Downgrade option | Any cancel |
| "Missing features" | Roadmap preview | Feature request logged |
| "Not using enough" | Pause subscription | 1-3 months pause |
| "Found alternative" | Comparison sheet | Offer trial extension |
| Any reason | Usage stats shown | "You've created 47 projects this month" |
```

### Dunning Management

```markdown
## Failed Payment Recovery Sequence

| Day | Action | Email | In-App |
|-----|--------|-------|--------|
| 0 | Payment fails | "Payment failed" | Banner |
| 3 | Retry | "Payment failed - please update" | Banner + modal |
| 7 | Retry + warning | "Account will be suspended" | Modal + email |
| 10 | Account restricted | "Update payment to continue" | Full restriction |
| 14 | Account suspended | "Final notice" | Read-only mode |
| 21 | Data deletion warning | "Account will be deleted" | Email only |
| 30 | Account deleted | — | — |

### Retry Schedule
- Day 0: Initial charge
- Day 3: Retry
- Day 7: Retry
- Day 10: Retry + user notification
- Day 14: Account restricted
```

### Win-Back Campaign

```markdown
## Churn Re-Engagement Sequence

### 30-Day (Week 1)
- Subject: "We miss you, [Name]"
- Content: New features since they left
- CTA: "Come back for free - 14 days"
- Goal: Re-engagement, not immediate revenue

### 60-Day (Week 8)
- Subject: "Here's what's new at [Product]"
- Content: Top 3 features launched
- CTA: "Get 50% off your first month back"
- Goal: Conversion offer

### 90-Day (Week 12)
- Subject: "Last chance - your data will be deleted"
- Content: Data deletion warning (if applicable)
- CTA: "Save your data" or final offer
- Goal: Final recovery attempt

### Survey on Cancel
- "Why are you leaving?" (select one)
- Required field before cancel confirmed
- Results → product insights + save offer triggers
```

## Common Mistakes

| # | Mistake | Fix |
|---|---------|-----|
| 1 | Optimizing low-traffic pages | Focus on highest-traffic, highest-drop-off pages first |
| 2 | Multiple elements changed | One variable per experiment |
| 3 | Stopping too early | Wait for statistical significance |
| 4 | "Submit" or "Click Here" CTA | Specific, benefit: "Start Free Trial" |
| 5 | Phone number upfront | Progressive profiling — ask later |
| 6 | No cancel save offer | 20-40% can be saved with right offer |
| 7 | Ignoring mobile | 60%+ traffic mobile — test mobile first |
| 8 | Insufficient traffic | Need ~1000 conversions/variant |
| 9 | No guard-rail metrics | Primary metric win ≠ overall win |
| 10 | Copy-paste best practices | Every audience different — test everything |
