Pinterest is a visual site where users can collect and organize images and videos by creating boards on different topics. Users "pin" images to their boards and can also like, comment on, and repin pins from other users. To get started, users sign up for an account and select boards to follow based on their interests. To be successful on Pinterest, users should plan their strategy, check sources, pin across different boards gradually over time, engage with other users by liking and repining their pins, use visually appealing photos, showcase their lifestyle or business, and be creative in their profile and pin descriptions.
