How do you make your customers happy?

Deadline for this story: End of Day June 9 

This is part of a weekly list post series, where we ask entrepreneurs questions outside of our standard catalog. We’ll publish this on IdeaMensch and Medium and potentially other publications about a week after our deadline. You’ll receive a link back directly to your project, company or organization’s homepage. Also, we’ll support every post with a paid and organic social advertising campaign.

Happy customers lead to successful businesses. Happy customers end up staying with you for longer. Happy customers spend more with your company or organization. Happy customers tell their friends about you. Happy customers are the bomb. So what do you do to make your customers happy? What’s your favorite strategy to increase customer retention? What do you do so customers come back more often and buy more? How do you track your customer’s satisfaction?

Don’t worry about answering them all but do tell us your favorite strategy to make your customers happy? What’s working for you?
