One may ask, where does Google make all their money? Most would think the money comes from all the services and products they offer. The answer to that is no. Google makes most of its money from advertisements.
Google AdWords features key words that visitors can click on, with each click putting money in Google's deep pocket. A few of these popular key words are insurance, loans and mortgage. Wait a minute. Those three seem to be closely related and just a touch shady!
Google doesn't just make money out of thin air by running these advertisements. Its the 1 billion, completely unique visitors that use Google every month. That's 1 in 7 people on the entire planet using Google!
