I think that today youtube is less poweful for clickbank than it was couple of years ago. Anyway, I see lots of very low quality and not valuable product movies on youtube. I hope that these are only for a backlink matter and nobody really expects sales from them. Today, the name of the game is to give value, real value, and if your movie doesn't provide that additional, new free value, then the effect may not be as you wish it would be = no sales. I assume that today the main purpose of the movie should be to redirect to a landing page with a opt in and less to expect to make a sale just from the youtube movie itself. What do you think?
