This video is so smart. First, the information he sings about is right on, so he’s done some research. Second, its clever enough that people are passing it around the web. In the past year its been viewed 450k times. Would he have had the same amount of exposure otherwise? Plus, he’s singing about SEO, and distributing the message via social marketing. There’s a good chance that he knows both well.

Nicely done. Very clever.
