You cant say that 100% traffic is good but yes if you get targeted traffic than you can have win - win situation . According to me most of webmasters have used it and seen a good boost in their traffic .
It has been my experience that YouTube question is much more difficult to convert than PPC traffic. I've had the best success sending PPC traffic to a landing page with a YouTube video on it. This way I can get targeted traffic and use video as a conversion tool rather than a traffic tool.
I think it would be very high quality traffic. When I watch a video on YouTube I rarely pay attention to the links, so if someone really does follow a link from a video, they truly are interested in the subject matter and are not just clicking links blindly.
I agree with you 100 %. I know myself. If I like some video and if is there a link ,I allwais visit that site,looking for more informations,or just click on your channel name to see more your clips . Untill now I have 2500 clips viewed ! Btw, What camera u suggest (not too expencive pls) !!! I am looking this days to bay good camera for quallity videos !
It all depends on your niche. If your site is all about videos then you would benefit from it, otherwise forget it.
