What This Documentation Covers
This is the technical reference for website auditing, analytics implementation, and tracking infrastructure. Every guide is written for practitioners — developers, analytics engineers, and technical marketers who need to solve real problems, not read marketing copy.
What you'll find here:
- Platform-specific integration guides for 80+ website platforms (WordPress, Shopify, Magento, Drupal, headless CMS, enterprise platforms, and more) — each with actual code, admin paths, and platform gotchas.
- Analytics platform documentation covering Google Analytics 4, Adobe Analytics, Matomo, Mixpanel, Amplitude, and 15+ other tools — setup, event tracking, ecommerce configuration, and debugging.
- Troubleshooting workflows for the issues audits actually find: events not firing, data layer misconfiguration, consent banner conflicts, Core Web Vitals failures, and security header problems.
- Compliance references for GDPR, CCPA, ePrivacy, Digital Markets Act, and other regulations that affect how you collect and process analytics data.

Learning Center
Foundational concepts for analytics implementation — useful if you're new to a topic or need a refresher on how consent management, server-side tagging, data layers, or attribution models work.
Getting Started
If you're setting up tracking on a specific platform: Go to Website Platforms, find your platform, and follow the GTM Setup guide first. GTM is the recommended foundation — once installed, you can add GA4, Meta Pixel, and other tags without touching your site code again.
If you're debugging a tracking issue: Start with Events Not Firing for the universal diagnostic workflow, then check your platform's specific troubleshooting guide for known conflicts.
If you're implementing ecommerce tracking: Your platform's GA4 Ecommerce guide covers the full purchase funnel. The data layer guide shows how to populate product and transaction data from your platform's backend.
If you need to understand a regulation: The Compliance section covers what each law requires and how it affects your analytics implementation — consent requirements, data retention rules, and cross-border transfer restrictions.
