you have to have a youtube id, then the video is displayed with an advert at the top. I assume the videos are actually adverts, as one was for h&m clothes. so do you earn when the user clicks to play it? do they have to watch all of it? there is also an advert displayed over the video at the bottom. not sure if this will annoy users or not. Also a bit worried about the content as my site is for kids really, and so not sure if there are going to be "happy slapping" videos on there. I have asked google adsense anyway. one video was title "what the buck?" which is potentially a bit rude. I don't really want to piss off parents who might be looking over the shoulder of their liddle angels. -Adam
