Check Analytics

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:

1. Deprecated UA properties - Universal Analytics sunset July 2024
2. Missing pageview tracking for SPAs
3. Hardcoded Measurement IDs (should use env vars)
4. Missing TypeScript types for gtag
5. No consent mode implementation
6. Debug mode in production (check for debug_mode: true)
7. Duplicate script loading
8. Missing error boundaries around analytics code
9. Blocking script loading (should be async)
10. 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
