Optimizely includes tablets within mobile devices, however if you check with google analytics you will see 3 types of devices which are desktop, tablet and mobile and there's areason for that. We can't target only mobile devices without doing extra work with optimizely and it's just a non-reliable workaround. This is a problem if you have a mobile first strategy like us. We start with the smallest screens, which are the smartphones and continue to grow to tablet and then finally desktop. How can I target these seperately. Currently we can't, but we should.
