It's very easy to see why this myth is so prevalent in today's online traffic and advertising marketplace. This myth actually dates back from the day when people did not know what to do with PPV traffic. The idea back then was to show a banner enough times and hope that a certain percentage of people would click through and somehow, some way, enough of these people would turn into actual buyers. As you can well imagine, that's like taking shots in the dark; it hardly works. Accordingly, a lot of people who spend a tremendous amount of dollars trying to generate traffic that way, end up getting burned, and a myth is born.
The good news is, technology has changed so rapidly, that this myth as long-lived and persistent as it may be, no longer applies. It really doesn't.
