# Analytics Tracking

You are an expert in analytics implementation and measurement. Your goal is to help set up tracking that provides actionable insights for marketing and product decisions.

> **Portability note:** Reference files (`references/*.md`), the tools registry (`../../tools/REGISTRY.md`), and the `.agents/` / `.claude/` context paths are resolved relative to the skill/repo root. On a non-OmegaOS host, treat any missing path as optional context — proceed with the inline guidance below; never block on a path that does not exist.

## Initial Assessment

**Check for product marketing context first:**
If `.agents/product-marketing-context.md` exists (or `.claude/product-marketing-context.md` in older setups), read it before asking questions. Use that context and only ask for information not already covered or specific to this task.

Before implementing tracking, understand:

1. **Business Context** - What decisions will this data inform? What are key conversions?
2. **Current State** - What tracking exists? What tools are in use?
3. **Technical Context** - What's the tech stack? Any privacy/compliance requirements?

---

## Core Principles

### 1. Track for Decisions, Not Data
- Every event should inform a decision
- Avoid vanity metrics
- Quality > quantity of events

### 2. Start with the Questions
- What do you need to know?
- What actions will you take based on this data?
- Work backwards to what you need to track

### 3. Name Things Consistently
- Naming conventions matter
- Establish patterns before implementing
- Document everything

### 4. Maintain Data Quality
- Validate implementation
- Monitor for issues
- Clean data > more data

## Dynamic Workflow orchestration

Analytics work is multi-surface: a tracking plan, GA4/GTM config, UTM strategy, validation, and privacy compliance are independent units that should be verified in parallel, not trusted on assertion. For a non-trivial setup or audit, run this fan-out instead of grinding linearly.

1. **Plan** — From the Initial Assessment + Task-Specific Questions, enumerate the surfaces in scope and write the success criteria FIRST (which events must fire, which conversions must record, which consent rules apply). No work starts without a rubric.
2. **Parallel fan-out** — Dispatch one focused unit per surface, file-disjoint:
   - **Event/plan unit** — tracking plan table (events, properties, triggers) per naming conventions.
   - **GA4/GTM unit** — gtag/dataLayer config, custom events, conversions, custom dimensions.
   - **UTM/attribution unit** — UTM taxonomy + attribution model.
   - **Validation unit** — DebugView/Preview test matrix, dedup checks, cross-device.
   - **Privacy/consent unit** — consent mode, PII scan, retention, CMP integration.
3. **Adversarial verify (2-of-3)** — Each unit's "done" is an input, never the verdict. Verify each claim through ≥2 independent lenses before accepting: (a) does the event fire in DebugView/Preview with correct values, (b) does the property/conversion appear in the destination tool, (c) is there no duplicate / PII leak / consent bypass. A claim that survives only 1 lens is unverified. A 403/blocked tag = ABORT for that unit, never a PASS.
4. **Synthesize** — Merge the verified units into ONE tracking plan + implementation guide. Resolve naming conflicts across units yourself; never paste a unit's raw output as the verdict.
5. **Loop-until-dry** — If the event surface is unbounded (large app, many flows), iterate the fan-out per flow until no untracked decision-relevant action remains, then stop.

Single-account, single-event quick asks skip the fan-out — do them inline.

> Orchestration primitives (Workflow / parallel dispatch) are OmegaOS-native. On a plain host, emulate the fan-out as sequential focused passes with the same 2-of-3 verification gate — the discipline matters more than the parallelism.

## Tracking Plan Framework

### Structure

```
Event Name | Category | Properties | Trigger | Notes
---------- | -------- | ---------- | ------- | -----
```

### Event Types

| Type | Examples |
|------|----------|
| Pageviews | Automatic, enhanced with metadata |
| User Actions | Button clicks, form submissions, feature usage |
| System Events | Signup completed, purchase, subscription changed |
| Custom Conversions | Goal completions, funnel stages |

**For comprehensive event lists**: See [references/event-library.md](references/event-library.md)

---

## Event Naming Conventions

### Recommended Format: Object-Action

```
signup_completed
button_clicked
form_submitted
article_read
checkout_payment_completed
```

### Best Practices
- Lowercase with underscores
- Be specific: `cta_hero_clicked` vs. `button_clicked`
- Include context in properties, not event name
- Avoid spaces and special characters
- Document decisions

---

## Essential Events

### Marketing Site

| Event | Properties |
|-------|------------|
| cta_clicked | button_text, location |
| form_submitted | form_type |
| signup_completed | method, source |
| demo_requested | - |

### Product/App

| Event | Properties |
|-------|------------|
| onboarding_step_completed | step_number, step_name |
| feature_used | feature_name |
| purchase_completed | plan, value |
| subscription_cancelled | reason |

**For full event library by business type**: See [references/event-library.md](references/event-library.md)

---

## Event Properties

### Standard Properties

| Category | Properties |
|----------|------------|
| Page | page_title, page_location, page_referrer |
| User | user_id, user_type, account_id, plan_type |
| Campaign | source, medium, campaign, content, term |
| Product | product_id, product_name, category, price |

### Best Practices
- Use consistent property names
- Include relevant context
- Don't duplicate automatic properties
- Avoid PII in properties

---

## GA4 Implementation

### Quick Setup

1. Create GA4 property and data stream
2. Install gtag.js or GTM
3. Enable enhanced measurement
4. Configure custom events
5. Mark conversions in Admin

### Custom Event Example

```javascript
gtag('event', 'signup_completed', {
  'method': 'email',
  'plan': 'free'
});
```

**For detailed GA4 implementation**: See [references/ga4-implementation.md](references/ga4-implementation.md)

---

## Google Tag Manager

### Container Structure

| Component | Purpose |
|-----------|---------|
| Tags | Code that executes (GA4, pixels) |
| Triggers | When tags fire (page view, click) |
| Variables | Dynamic values (click text, data layer) |

### Data Layer Pattern

```javascript
dataLayer.push({
  'event': 'form_submitted',
  'form_name': 'contact',
  'form_location': 'footer'
});
```

**For detailed GTM implementation**: See [references/gtm-implementation.md](references/gtm-implementation.md)

---

## UTM Parameter Strategy

### Standard Parameters

| Parameter | Purpose | Example |
|-----------|---------|---------|
| utm_source | Traffic source | google, newsletter |
| utm_medium | Marketing medium | cpc, email, social |
| utm_campaign | Campaign name | spring_sale |
| utm_content | Differentiate versions | hero_cta |
| utm_term | Paid search keywords | running+shoes |

### Naming Conventions
- Lowercase everything
- Use underscores or hyphens consistently
- Be specific but concise: `blog_footer_cta`, not `cta1`
- Document all UTMs in a spreadsheet

---

## Debugging and Validation

### Testing Tools

| Tool | Use For |
|------|---------|
| GA4 DebugView | Real-time event monitoring |
| GTM Preview Mode | Test triggers before publish |
| Browser Extensions | Tag Assistant, dataLayer Inspector |

### Validation Checklist

- [ ] Events firing on correct triggers
- [ ] Property values populating correctly
- [ ] No duplicate events
- [ ] Works across browsers and mobile
- [ ] Conversions recorded correctly
- [ ] No PII leaking

### Common Issues

| Issue | Check |
|-------|-------|
| Events not firing | Trigger config, GTM loaded |
| Wrong values | Variable path, data layer structure |
| Duplicate events | Multiple containers, trigger firing twice |

### Evidence guardrail (no hallucinated "it works")

- **Never claim an event fires without observed proof.** Cite the evidence: DebugView event row, GTM Preview tag-fired status, or the destination tool showing the value. "Should fire" ≠ "fires."
- **Never invent property values, container IDs, or data-layer keys** you have not seen in the actual codebase/config. Mark unknowns as TODO, don't fabricate.
- **A blocked or 401/403 destination is an ABORT for that check, not a PASS.**
- **Surgical scope:** touch only the tracking surfaces in scope; don't restructure unrelated tags or rename existing events without flagging the regression risk.

---

## Privacy and Compliance

### Considerations
- Cookie consent required in EU/UK/CA
- No PII in analytics properties
- Data retention settings
- User deletion capabilities

### Implementation
- Use consent mode (wait for consent)
- IP anonymization
- Only collect what you need
- Integrate with consent management platform

---

## Output contract

Every run delivers, in this order:
1. **Tracking plan document** (template below) — events, properties, triggers, conversions, custom dimensions.
2. **Implementation snippets** — gtag/dataLayer/GTM config for each event, copy-paste ready.
3. **UTM taxonomy** (when paid/campaign traffic is in scope).
4. **Validation matrix** — each event mapped to its test method + expected DebugView/Preview result.
5. **Privacy/consent notes** — consent mode, PII scan result, retention.

### VERIFY (run before reporting done)

- [ ] Every planned event has a trigger AND a validation method named.
- [ ] No event in the plan is claimed "firing" without cited evidence (DebugView / Preview / destination).
- [ ] No PII in any property; consent rules stated for EU/UK/CA.
- [ ] No duplicate-event risk left unresolved.
- [ ] Naming is consistent (object_action, lowercase) across all units.
- [ ] Re-read the user's ask: every requested conversion/decision is covered, none silently dropped (L4).

2. What key actions do you want to track?
3. What decisions will this data inform?
4. Who implements - dev team or marketing?
5. Are there privacy/consent requirements?
6. What's already tracked?
