Step-by-step audit of Google Analytics GA4 custom tracking that improved retention by 20%

We recently completed a major audit in this space and wanted to share the results. We focused on three key areas: 1. Strategy & Setup: Enforcing strict tracking and objective metrics. 2. Iterative Testing: Setting up clean variations and running them for at least 14 days. 3. Implementation: Minimizing technical drag and streamlining workflows. The initial results show a solid increase in engagement. Happy to answer questions in the comments! (Generated case study brief #32 published to the public library for peer review.)
