Depending on how secure or insecure, as the case may be, about your privacy you may have noticed that Google has not only become a leader in the world of search engines. Google is also a competitor in browsing software, ecommerce and soon a leader in the internet market. Now in terms of individual products each of these offers us something new as consumers, a new way to find things, a new way to buy and search the internet. However, this does come at a price in terms of our privacy and we ourselves may not the true extent to what they know.

Now one thing you might not know about supermarkets that give you cards is that they actually track what you buy and when. Individually this may not seem like anything that bad, but when this is done on a mass scale it means that companies are able to see what is most bought and least bought and adjusts the prices as such. IN the same way Google also collects information from what you search to what sites you go on to possibly what you buy (Google checkout). By using all of these things they can see what people most want and then simply create a better, cheaper or even open source version of it to cut out competition.

In terms of what they can do for us, the sellers on the net, it will mean that when you use their PPC system you will get better tailored ads showed to those people who are actually actively looking for that kind of stuff. Meaning less useless clicks, better conversion rates and possibly, lower costs per click as well.

However, would the cost of Google knowing everything about you be worth the trade? Only time and customer reactions will tell.
