http://www.marketingovercoffee.com/ is an excellent podcast run by a pair of online marketing veterans who regularly hand out simple and effective advice for enhancing anyone's online marketing strategy. One recent tip for YouTube videos where they suggested placing an appropriate URl at the beginning of the description section of a video. YouTube automatically turns a plain URL into an active link, which can then point back to a blog, web site, or other online resource related to the video.
Before I made this very minor change, only those viewers who went out of their way to open the entire description, or who had the desire to watch the entire video would find the link. Now, even a casual visitor to one of AirSafe.com's YouTube videos will know where to go for more information. Time will tell if this leads to as significantly greater traffic on the web site.
