Anyone who sells anything from croissants to chemicals knows the painful truth of so many product-focused businesses. You end up giving away a lot of services for free.

Now, no matter the size of your business, you have an easy tool for selling your knowledge with MindBites. Here’s how it works. Sign up to become an author, create your short video, upload it, promote it, and then, ideally wait for your viewers to show up. Every time someone views your video, you earn $1. Viewers pay between 1.69 and $1.99 to purchase your small video. It’s early going in the sale of video content, so you’re not likely to make a fortune.

If you or your brand already have significant star power, let this serve as an example that you can apply in a site of your own. In any case, no matter what business you’re in, think about how you might be able to monetize all of the services that you currently offer for free.
