2 fingers on the pulse of search
Google has 2 different ways for those curious enough to wonder what people are searching for and how they search. Since July 2001, Google has had their Zeitgeist available. It shows what people are searching for in various areas of interest. The great thing about it is that they archive this information. So say you want to relive what was the big story 1 year ago in January, it is right there for you.
The fun doesn’t end there for stat freaks though. I just came across an area where Google posts marketing information in various business fields. If you are curious to know averages of what people are spending to get a ROI, the information is there for you. This is all very good information and time saving for marketers.
