一步数据昨天谷歌分析官方博客给出了GA4替换UA的时间表，核心传达信息就是
1、普通用户有15个月的过渡期，直到2023年7月1日；
2、360用户有18个月的过渡期，直到2023年10月1日；
还没熟悉GA4的可以demo站玩起来了，虽然相比UA有不小的改动，不过总体而言化繁为简还是体验更好的，尤其是目标追踪和可视化分析方面新GA4下了不少功夫。
官方关于新旧更替的原话是：
Without a modern measurement solution, you leave essential insights on the table that can impact your business. So now is the time to make Google Analytics 4 your cross-platform Analytics solution. We will begin sunsetting Universal Analytics — the previous generation of Analytics — next year. All standard Universal Analytics properties will stop processing new hits on July 1, 2023. Given the new Analytics 360 experience was recently introduced, Universal Analytics 360 properties will receive an additional three months of new hit processing, ending on October 1, 2023.
