IP Changers to the Rescue
Every one can remember the old days of online advertisements when you would have all sorts of ads pop up on your screen that had absolutely nothing to do with you, your interests, or your life. Consider the sports enthusiast; if while surfing his fantasy football account, making some tweaks here and there, he encounters an ad for the latest new miracle grow for your garden. Likely this ad will simply be getting in the way of him and the screen, so away it goes. Advertisers wised up though, and they can’t make any money unless you buy their stuff, so they have to sell better.
Thus came the advent of the behavioral advertising. These advertisers are a bit more invasive than the previous pop-up ads, which were just annoying. These systems actually scan your browsing history without your consent or knowledge and determine your likes and dislikes based on them.
It works like this; let’s use the fantasy football user again. The program will sift through his browsing history, and upon seeing many sites related to sports (perhaps ESPN and its affiliates) will determine those would be the best things to throw at him. Gone are the gardening and baby doll ads, and here are the new custom football gear ads, meet a player ads, etc. This man is much more likely to click on these than he is to order ten bundles of miracle-gro garden solution.
