It's a bit weird that they don't list what formula they used to get the score they calculated. It would have been pretty easy just to list the raw "Web Search Interest," but it would be interesting to know how they are getting a value for search interest by comparing to CoD.
For those interested, I've looked up the totals (which seem to be normalized against 100, so I'm not really sure if they mean anything. Though smaller games tend to get really small numbers.)
The format is:
Game - total search interest over the last 30 days -> total interest over the last 7 days.
Halo Reach - 58 -> 88
Gran Turismo 5 - 71 -> 84
Gears of War 3 - 76 -> 89
Fable 3 - 56 -> 88
Crackdown 2 - 50 -> 76
The Last Guardian - 73 -> 90
Killzone 3 - 43 -> 73
LittleBigPlanet 2 - 59 -> 97
Infamous 2 - 30 -> 86
Gran Turismo 5 is most popular in Australia... Killzone 3 does its best in the UK (though it doesn't seem to have any interest outside of the UK and US... Fable 3 also doesn't seem to have data outside the US... very weird.)
