How to increase engangement and client retention in your business?

How to increase engangement and client retention in your business? I learned a lesson today spending all day on my couch playing a game, incapable of doing anything else. And this is how to use milestones and instant gratification to help your business have more engaged members or clients that will stay loyal for longer. What you need to do: 1. Create milestones of achievements for your community. 2. Celebrate them with your members/clients when they reach them. 3. Send them a physical gift when they do. Now the next one will push harder and all the rest will stay for longer just because there are "trophies" to ve earned. FB does it, forums do it, well established businesses do it too. Why don't you?
