Google Analytics 4 (GA4) Manager

This skill provides a standardized approach to setting up, verifying, and optimizing Google Analytics 4 properties. It covers programmatic setup via the Google Analytics Admin API, manual code integration, and optimization audits.

How to use this skill

1. Assess Current State: Check if the website currently has Google Analytics. Use web scraping tools (like Firecrawl or native page requests) to look for G-XXXXXXXXXX IDs in the source code.
2. Setup Strategy: Determine if you need to create a new GA4 property or integrate an existing one.
3. Programmatic Creation (Optional): If the user provides a Google Cloud Service Account with Analytics Admin access, use the included ga_admin.py script to create properties and data streams programmatically.
4. Code Integration: Inject the correct GA4 implementation code into the project (e.g., using @next/third-parties/google for Next.js, or raw gtag.js for plain HTML).
5. Optimization & Auditing: Review the site's layout and suggest custom events for key interactions (e.g., lead forms, e-commerce purchases, outbound clicks).
