With Instagram users can come in through old and new posts as you can constantly build on your content and utilize older content to keep it fresh. You need to decide what works best for your business.

The UK is the 5th leading country by new user volume and platform market share for Snapchat, which is certainly something to keep in mind if you are UK based.
Snapchat is already attracting 25 percent more new users worldwide than Instagram, and in the U.S., U.K., Brazil, France and Germany, Snapchat is growing between 63 percent and 76 percent.
