Instagram is a mobile platform and since 80% of social media browsing takes place on mobile devices there should be no doubt in your mind about building a presence on this platform. Users can view Instagram as a web page but can only post photos from their mobile devices.
This may seem like a con to some business owners but the way people are shopping has changed since the advent of the smartphone. 80% of shoppers use their mobile phones to look up product reviews or compare prices online.
It’s quick and convenient because smartphones are small and compact and most people have one with them 24/7. If you want your business to be successful, you will need to stay up with the trends. Source
