Pinterest, Instagram, and Foursquare are social media platforms that can be used together for internet marketing. Pinterest and Instagram are both photo-based platforms that allow searching by category and sharing to social media. Foursquare's check-in feature differs from the platforms by being location-based. A campaign for a travel agency could involve users checking in on locations with Foursquare, uploading photos to Instagram, and creating pinboards on Pinterest of their travel photos for a contest. Integrating the platforms could increase engagement for brands and opportunities for rewards.
