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.

Initial Assessment

Check for product marketing context first: If .claude/product-marketing-context.md exists, 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:

Business Context - What decisions will this data inform? What are key conversions?
Current State - What tracking exists? What tools are in use?
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

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

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

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

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

Custom Event Example

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

For detailed GA4 implementation: See 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

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

For detailed GTM implementation: See 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 |

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
