When Pinterest first started in 2010 many brands were skeptical of yet another social media site and no one expected it to grow as quickly as it did. Today, Pinterest boasts over 70 million users and 42 percent of online women are Pinterest users. Its incredible surge in popularity is due to its focus on visuals and its inspirational/aspirational aspect. It has also become popular among retailers as well as 69 percent of online consumers that visit Pinterest find something on the site that they have either purchased or want to purchase. Even with the growth in users, Pinterest still offers an excellent opportunity to build brand awareness and sales. So how do you use Pinterest as a marketing tool?
