Facebook and Twitter are still the top business networks, but businesses often tend to struggle with more visual platforms like Instagram, Pinterest, Tumblr and Snapchat. All of these platforms have huge consumer audiences, but many businesses don't realize how big they really are, how effective they can be and how to make them work for their brand. If you have a background in social media marketing and a passion for photography, focusing your consulting business on one specific platform, like Instagram, can be a great way to make money while helping other businesses improve their content and achieve their business goals.
However, this only further illuminates the exponential rise of online business today. Considering that the internet is still largely in its infancy, as the modern conveniences give way to near-instant delivery of products via drones, 3D printing and other means, and as virtual and augmented reality help to improve the online shopping experience, nearly all our commerce will eventually be conducted through online channels rather than offline channels.
