Enjoy making silly videos? Even short, silly videos can sell products online. Find an product worth promoting that has an affiliate program, then target your video toward potential customers of that product. In your video summary on YouTube, place your affiliate link for the product, and after the video, do a 30-second still frame showing a short URL where people can buy the product. If your video is funny, informative, or useful, you may sell some products. Big tip: Try to promote a product that makes you a fair amount of money for each sale, but doesn't cost a whole lot for the potential customer. You can find products on Commission Junction. for one.
