Pinterest offers a wide variety of sources covering multiple personal interests, and people often use Pinterest for inspiration or to promote their brands. Many people use Pinterest for inspiration or as an easier way to bookmark Web pages, but businesses have begun advertising their products on Pinterest. Some advertisement pins are interspersed with user's pins, but most businesses have their own Pinterest profiles with boards showcasing their products or talents.
Pinterest is free and easy to use. Each picture is called a "pin," and when the pin is clicked, it links the user to the website from where it was shared. Every pin is sorted into a descriptive category depending on what the pin is. As of September 2015, there are 36 categories that pins can be classified under.
Each user with his own Pinterest account creates boards to organize his pins. Each board is named and customized to the user's liking. The boards are made public or private, and other Pinterest users can choose to follow one or all of the public boards they find interesting. If a person does not want to pins on certain boards, she can simply "like" them instead, which lists them all into separate categories.
