Online Advertising
Are you a business trying to decide how to advertise? Where to advertise and whom the advertisements need to be targeted for. Perhaps the business is going to target certain markets, such as teenagers. They are most likely going to have their ads pop up when then teenager logs on to Facebook. How does the advertiser know who is a teenager? Probably by the teenagers click stream. The advertiser will have a general idea of what this person is interested in by the websites they had visited.
Businesses may also chose to advertise by paying per click, on websites such as Google. That enables their business to show up at the top of the list when someone is searching for a specific need. Each time their link is clicked, one of their pay per clicks is used up. This would be a great way for most businesses to advertise if there wasn't click fraud occurring. Click fraud is when software or hired people click on the ads with no intent on purchasing their service, using up the number of pay per clicks the advertiser has paid for.
