Pinterest is an online platform that allows users to collect and share images, videos and other content on virtual pinboards. It is popular among women aged under 44 and early adopters. Around 87% of Pinterest users make purchases influenced by content on the platform. Businesses can use Pinterest to connect with target audiences, showcase products and increase brand awareness through free marketing. Analytics tools provide metrics on user engagement, clicks and conversions to measure the effectiveness of promoted pins for businesses. Case studies show that companies like Lowe's saw increased click-through and lower costs per click from Pinterest advertising campaigns.
