Did you know that 80-90% of A/B tests often fail to deliver statistically significant results, frequently due to tracking issues? I've personally wrestled with ensuring accurate experiment group data integrity and reliable conversion attribution within GA4, especially when integrating with third-party testing tools.

My team now focuses heavily on meticulous pre-test validation of data layer events and custom dimensions for each variation *before* launch to catch discrepancies early. What specific methods are you using to robustly track and validate your A/B test results, particularly within GA4, to avoid those common tracking pitfalls? Any insights on reconciling platform data with GA4 events?
