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

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

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
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
