Instagram is a match made in heaven for those looking to use social media for ecommerce and reach out to people who are on their phones, since it's not even that common for users to open up Instagram on regular computers.
For quite some time you weren't even able to access the Instagram homepage from a PC or MAC, and you still can't post images from the primary Instagram website. What does this mean? Instagram is one of the most intimate social media networks in the world, since you gain access to every follower's personal phone. In short, it's wonderful for generating sales and pushing more people to your online store.
