Doing a comparison of the current google vs the new “google caffeine” using my tool fashioned from doing a split query of Ajax API:
http://www.cupofgooglecaffeine.info/googlevsgoogle.html
One finds that there is very little difference between the two other than more relevant results and even current ones are placed at the top of the list. One determines from such results that if you want to get higher rankings on google in the future, you are gonna need to get very social and update your websites fairly frequently with those same keywords.
Go ahead put in your own search terms and give the tool a whirl on your own keywords.
