When you're trying to grow your repeat customers you want to get as much feedback as you can. You can always choose to ignore or not follow bad ideas but the more data you have, the better.
That's why you'd want to ask customers what made them come back after they place their second order.
I wanted to ask, what caused you to come back and place this second order?
Keep it simple. Don't worry about turning them into reviews, testimonials, or have a large survey for them to fill out. Just ask them and collect their responses in a document.
Do this enough and you'll start to hear a variety of reasons that no one thought of. Pick out the good ones and find ways to improve your messaging so those get in front of all customers.
This works especially well when you combine it with numeric data analysis. Then you have actual data backing up opinions and feelings.
