Why Every Website Needs GA4 In the world of digital marketing, data is your compass. Google Analytics 4 (GA4) officially replaced the legacy Universal Analytics in 2023, introducing a brand-new event-driven tracking architecture. Many users feel lost after upgrading to the unfamiliar interface — where did the reports go? What happened to bounce rate? How do you set up funnels?
