Taken from the Wall Street Journal:

First - how does Google make money? They collect and use your information to have sponsored ads on places (like even this blog). If you do a Google search, they put relevant information on the top of the search and collect because the company paid to be among the top results - and collect more if you click on the ad / link.
Safari was intended to not allow tracking software - so if you went to HomeDepot.Com and looks for a new kitchen countertop; and then used Google to search for countertops, Safari would not know that you had already been to HomeDepot.com.
BUT ... Google found a way around this with what acted like an 'invisible form' - but opened Safari to be tracked.
When the Wall Street Journal found this and asked, Google (supposedly) stopped this.
(For us PC users, I think everything I do is tracked - and I need to occasionally 'clean-out' my tracking cookies!)
