They can be used for a wide variety of purposes, including identifying you as a unique user. In most cases, they're used for the first time you visit a site, or for each time you come back to the site later. For instance, if you go to the Google Play Store and look at an app you bought recently, you'll see a cookie for that site in your browser. When you come back to the site later, that cookie is used to show you additional information about the app, such as reviews.
