Are you currently running experiments or personalisations on Google Optimize?
If so, you will have heard that the platform will officially be closed down at the end of September this year. Therefore, any experiments and personalisations still active on that date will come to an end.
The latest news from Google is that they are committed to moving its A/B testing function to Google Analytics 4 but it hasn't yet made clear which optimisation features it intends to integrate. Therefore, businesses that rely on Google Optimize today will have to find a new solution and should start researching alternatives.
