GA4 Is Not Just an Upgrade — It Is a Different Way of Thinking
When Google forced the sunset of Universal Analytics in 2023, a lot of marketing professionals were caught flat-footed. Three years of working in GA4 since its introduction, and many agencies still had not made the conceptual shift from session-based to event-based analytics. I am Derick Downs, and the GA4 transition was something I started preparing for in 2020 — partly out of professional discipline and partly because I had too many clients depending on clean data to get caught scrambling.
This post is my honest take on the GA4 certification and what it means to actually use GA4 well for real client campaigns in San Diego and beyond.
What Changed: The Core Conceptual Shift
Universal Analytics was built around sessions and pageviews. A session was a container, and everything inside it — page visits, button clicks, form submissions — got attributed to that session. GA4 is built around events. Every interaction is an event: a page view is an event, a scroll is an event, a video play is an event, a purchase is an event. This is a more flexible model, but it requires rethinking how you set up and interpret your data.
For Derick Downs Digital Marketing clients, the GA4 migration required auditing every conversion tracking setup, rebuilding goals as conversion events, reconfiguring audience definitions, and reconciling data discrepancies between the old and new platforms. It was significant work across 25+ client accounts, and doing it right required genuine platform expertise — not just a surface-level migration checkbox.
What the GA4 Certification Covers
The Google Analytics 4 certification tests knowledge across several areas that are genuinely important for anyone running analytics for business clients. The exam covers event-based data collection and the GA4 data model, configuring key events (conversions) and custom events, using Explorations for custom analysis beyond standard reports, audience building for remarketing and Google Ads integration, cross-platform tracking (web plus app), and understanding BigQuery export for advanced data analysis.
The certification is not trivial. Practitioners who only worked in Universal Analytics and tried to apply the same mental model to GA4 struggled with the exam — and in practice, ran poorly configured accounts that gave clients misleading data. At Derick Downs Digital Marketing, passing the GA4 certification was validation that my transition from UA to GA4 was technically sound, not just functionally approximate.
Three Years of GA4 Practice: What I Have Learned
Certification gives you the framework. Daily practice with real accounts gives you the judgment. Here is what three-plus years of working in GA4 across 25+ client accounts has taught me:
Configuration matters enormously. GA4 out of the box gives you basic enhanced measurement events. But the clients who get real value from their analytics data have carefully planned event taxonomies, properly configured conversion events, and meaningful custom dimensions that capture business-specific data. A law firm needs to track phone call initiations and form submissions differently than a med spa tracking consultation bookings. Getting that right requires setup expertise.
Attribution in GA4 is different. The default Attribution model in GA4 is data-driven attribution, which uses machine learning to distribute credit across touchpoints. This is better than last-click attribution for understanding true campaign contribution — but it requires sufficient conversion volume to be reliable. For lower-traffic clients, Derick Downs uses first-click or linear attribution models to maintain interpretability.
The Exploration reports are underused. Most practitioners live in the standard GA4 reports and miss the Explorations section, which is where you build funnel analyses, path explorations, cohort analyses, and segment overlap reports. This is where the real analytical insight lives for businesses that want to understand user behavior, not just traffic volume.
GA4 and Google Ads: The Integration That Matters
The reason GA4 certification is increasingly inseparable from Google Ads expertise is the integration between the two platforms. GA4 audiences flow directly into Google Ads for remarketing and Smart Bidding. GA4 conversion events drive Google Ads Smart Bidding algorithms. Without a properly configured GA4 setup, Google Ads automated bidding is optimizing against imprecise or incomplete conversion data — which degrades campaign performance in ways that are hard to diagnose without understanding both platforms.
As a Google Partner with both Google Ads and GA4 certifications, Derick Downs manages this integration as a unified system, not two separate tools. That is what produces reliable attribution and accurate performance reporting for clients.

Frequently Asked Questions
Q: What is the Google Analytics 4 certification?
The Google Analytics 4 (GA4) certification is a professional credential from Google validating proficiency in the GA4 platform, including event-based data collection, conversion configuration, audience building, Explorations analysis, and Google Ads integration. Derick Downs holds active GA4 certification alongside Google Ads certification and Google Partner status.
Q: How does GA4 differ from Universal Analytics?
Google Analytics 4 uses an event-based data model rather than Universal Analytics session-based model. Every user interaction is an event, providing more flexibility for tracking complex user journeys. GA4 also integrates more deeply with Google Ads and supports cross-platform (web and app) tracking. Derick Downs managed GA4 migration for 25+ client accounts.
Q: Why does GA4 matter for Google Ads campaigns?
GA4 conversion events and audiences flow directly into Google Ads Smart Bidding algorithms. A properly configured GA4 setup provides clean conversion data that improves bidding optimization. Without GA4 expertise, Google Ads campaigns may be optimizing against incomplete or misconfigured conversion data, degrading performance.
