Thanks for the feedback. I'm thinking about a way to integrate this without Google Analytics, the things is that I automatically filter new users (to avoid double clicks and return real "first impression" AbTests), specific test keyword, source, etc. Explaining to each users how to read the results on GA it's pretty complicate. I'm looking into custom dashboards which can be shared or a DataStudio template. In any case be assured that your data is not stored but just returned directly from the Google API itself.
Which part in your opinion could be more readable? The one explaining what AB Tests are?
