Probably worth mentioning that the Google Content Experiments framework is in the process of being replaced with Google Optimize (currently in a private beta) which does NOT make use of multi-armed bandits much to my confusion and disappointment.
Huh. So do you know if they do anything help with repeat testing/peeking?
Optimizely takes an interesting approach: they apply repeat testing methods, segmenting the tests by user views of the results. Like 30x more complicated than multi-bandit, but they don't need a feedback mechanism.
