Well, AdSense is where it stands today, giving benefits for everybody in the game because it exploits a gap in the Internet’s advertising model.
You see, the Internet is a very interactive environment, and its interactions come from the people who are browsing. They choose whether or not to follow a certain link and the term “navigating” is probably the most precise one at describing this situation.
So AdSense is great because it links together buyers and sellers. Yes, you have to hand it out to Google for a brilliant idea. They know there are people out there that want to buy stuff and people who want to sell them what they’re interested in. And Google AdSense helps members of the two categories find each other.
It works for the visitors, because the model is very transparent. You don’t see a huge graphic banner which tries to lure you into buying something. You just see a few words. And if you like what you see you can just click it. It works because visitors don’t have that feeling of someone trying to lure them into spending money. Ironically, however, they’re wrong.
