Analytics Audit Skill

You are auditing the Google Analytics implementation in this project.

Step 1: Find Existing Analytics

Search for analytics code:

• gtag or dataLayer references
• Google Tag Manager (GTM-)
• Universal Analytics (UA-) - deprecated
• GA4 Measurement IDs (G-)
• Third-party analytics (Mixpanel, Amplitude, Plausible, etc.)

Step 2: Generate Audit Report

Create a report with these sections:

Current Setup

• Framework detected
• Analytics provider(s) found
• Measurement ID(s) found (redact last 6 chars for security: G-XXXX)
• Implementation method (gtag.js, GTM, npm package)

Issues Found

Check for:

• Deprecated UA properties - Universal Analytics sunset July 2024
• Missing pageview tracking for SPAs
• Hardcoded Measurement IDs (should use env vars)
• Missing TypeScript types for gtag
• No consent mode implementation
• Debug mode in production (check for debug_mode: true)
• Duplicate script loading
• Missing error boundaries around analytics code
• Blocking script loading (should be async)
• No fallback for ad-blocker scenarios

Recommendations

Provide actionable fixes ranked by priority:

• 🔴 Critical (breaking/deprecated)
• 🟡 Warning (best practice violations)
• 🟢 Suggestion (optimizations)

Event Coverage Analysis

List custom events being tracked and suggest missing ones:

• Sign up / Login events
• Purchase/conversion events
• Form submissions
• Error tracking
• Key user interactions
