Answers: You'd make completely little, if any at all.
It's a awfully ineffective way of selling as, people simply freshly don't go on youtube to study slideshows, or are not very credible to visit a association you post up.
If you put some entertaining content up and then put a contact to a product related to what's in your video and it get a lot of hits, you enjoy a marketing opportunity there.
But unanimously, no, unless you know how to market youtube successfully.
