When you do use YouTube to drive targeted traffic to any site you have that has AdSense, bear in mind that writing a keyword rich and unique video description with links to your website, blog or forum with AdSense in it has the potential to not only increase traffic from the video you've uploaded to YouTube with your links, but also increase your online ad revenue from AdSense, or other affiliate programs. This is the sole purpose of many webmasters and online marketers, in using YouTube, and other video sharing services, to make money from free YouTube video traffic and increase the popularity of their sites as the links are embedded in the video description, so that they can possibly earn a living on the world wide web doing things such as that.
In addition, if somewhere down the line you are approved as a YouTube partner, you can automatically have Google ads placed in all YouTube videos you upload. In addition to having Google AdSense on any site of choice and having the links placed in the video description everytime you upload a video, you have the extra potential as a YouTube partner to earn extra AdSense revenue, and have links to other affiliated sites in your YouTube channel, as a YouTube partner/content video provider. Just something for you to think about, and stay hopeful of =)
