I enabled the new automatic experiments feature a few weeks ago, but am slightly stumped. Do I need to manually do anything for this feature to work, or will Adsense eventually start giving me hints on tweaks I could make to the set-up in order to increate revenue?
I see the option of doing my own manual experiments (I haven't done any of these) and below it, "automatic experiments" with, so far, nothing in there.
Am i missing something?
