Effective customer satisfaction surveys include three main sections:

* Overall Satisfaction Questions
* Dimension Questions
* Demographic Questions

Here are some good overall satisfaction questions to ask:

* How would you rate your overall experience with our service?
* How likely are you to return to our store?
* How likely are you to recommend our services to your friends and family?
