Rarely would I ever give advice that included putting material on an external site rather than your own site. But when considering videos I have to say that making sure it is branded correctly and posted to YouTube.com is critical. YouTube.com gives small businesses the possiblity to have national exposure, possibly even more than a a network advertising campaign. It would require an extremely viral video but it has been done by many companies as well as individuals.
There are just too many viewer on YouTube.com to pridefully say you are going to post your video on your site and wait for the video linkbait to catch on. With YouTube.com this can happen overnight with the right video and your traffic would be derived from the grass roots marketing of your video on YouTube.com.
Once the video is posted on YouTube.com you can post it on your site and YouTube.com will pick up the link to your site. It will be tagged with NoFollow, so no link juice, but it will provide traffic through the link. You will also want to brand the video with your web address.
