How do you distinguish the layouts/GUIs?
I definatly have 2 different kind of SERPs which in every case seem to be an "old one" and an "updated one" with an algo-change (or at least more recent data influencing the SERPs while the "old one" seems to be stuck 2 or 3 month ago). I see them as Non-Caffeine and Caffeine (which might be discussed controversialy of course).
I identify "Caffeine" as well with some keywords where is not much flux in the SERPs and which has almost equel SERPs to the one on the test-DC we got last year. When I get this SERPs, I see the "udpated one" on other keywords, so for me this is "Caffeine" (or the resulting SERPs from the change of the infrastucture).
