At long last, Instagram will come with analytics, as part of their new business profiles. There have been a few apps on the market to work out the best performing times, and check which of your Instagram posts were the most popular. However, it makes a lot of sense for Instagram to provide this in-house.
This is all part of a move to make Instagram align more closely with Facebook. Other features to look out for include a 'Contact' button and a 'Get Directions' feature.
It'll be a while before this is widely available, but this looks like great news for businesses everywhere...
