Video is a great tool....I`ve used it for many projects this year alone and I`m ecstatic with the results. Here is one of my sample projects --- and this site on average pulls in 400 students per day --- I don`t pay any advertising, I have several videos planted on YouTube as lead generators-- ignore the quality of the video (sometimes when you do your own stuff, the quality goes out the window)
Let me warn you...this was my first video of me actually doing something for myself, so I look kinda crazy, but just too lazy to go back and record over it, but its fun:
I`ve also used video to sell domain names (telling `targeted prospects` why they needed the domain name)...here is another client of mine who uses video, we shot that in my garage --- in fact, he`s coming over so we can reshoot the video (i just purchased a better camera and bought more lighting when I realized I`d be doing video full-time): http://www.KenCompton.com
Use video -- I and my clients are getting great results.
