We know that A/B testing is an important part of managing content; however, as of August 7th, 2019, Google will no longer be supporting the Prismic Experiments feature in Analytics. This means that the feature will no longer work in Prismic starting on that date.
All existing experiments will continue to run, but you will not be able to create or start any new experiments from August 7th onwards.
Google has proposed the option of replacing the feature with their new Optimize product. At the moment Optimize does not provide an API - meaning that it is not a viable solution for Prismic users.
We will continue to explore different options and will keep all of our users notified of any changes or options that become available.
Do not hesitate to contact us if you have any questions.
