The beauty of this kind of advertising is that you will only pay when people actually watch your video. If searchers do not click on your video advertisement, you don’t pay a thing. Imagine doing newspaper advertising where you could determine if someone actually looks at your newsprint advertisement – great! That’s what you paid for – but if they don’t look at it – you don’t pay. Of course there’s no way to determine that, which means that you pay a flat rate, no matter who looks at your advertisement or not.
