This is the best thing I’ve seen on YouTube for a long time:

Are you using video to market your website? If you’re not, you’re really missing out. Although this video isn’t really marketing anything except a really cute and talented little singer, you can use video the same way to promote your products.

A video like this is the “viral” quality: it will get viewed and passed along to millions of people. Find a way to tie it (or a fun video like it) in to your marketing campaign and “viola” - you have traffic that you can’t even handle with tons of backlinks too.

Now go and do likewise
