Pinterest, for those who have never used it, is a social sharing/bookmarking site for the sharing of images. There are other photo sites, but Pinterest is the largest and most important. Here's how Pinterest works: Pinterest users create boards based around a common topic and pin images from around the web to their boards. It follows the model of a bookmarking site. Each pinned image is also a link back to your site. Here's a board I made for fun: https://pinterest.com/tastyplacement/ducati-italian-bikes/.

Pinterest has grown tremendously in popularity in recent years. For some businesses and bloggers, it can be a goldmine of web visitors. If you sell any type of visual product—clothing, art, interior design, cars—then Pinterest can spread your images like wildfire.
