There is one thing I still don’t understand about the internet: I use google constantly and surf more than most people, especially since I don’t have TV in my home.
But I have NEVER bought anything advertised on the internet. Never. Where is the money being made? I don’t get it.
I'm not in advertising, but I'd guess "Volume".
Google charges a fraction of a cent per "click". Adds up.
Company that's advertising only needs to sell one widget, and that covers a whole bunch of "clicks".
Add in the fact that the advertising is directed at you, personally, based on your surfing habits, and I suppose that it's relatively effective. Well, maybe not on you, but on some people.
I, too, would need to think pretty hard as to whether I bought something based on internet advertising. I probably have, but not much.
