The timing of your feedback request is one of the most decisive factor for customers to give you feedback or not. Make sure you are asking feedback at the right time and the right place.
Here're 3 tips:
1. Customers respond best in the moment, using a feedback pop-up to show right after a certain event will get you high respond rate and accurate feedback.
2. Don't ask irrelevant questions, if a customer is browsing shoes and you ask for feedback on your t-shirt collection, they will not be pleased to answer.
3. Ask for feedback only when the customer is engaged, the customers that interacts with you regularly are the ones that are more likely to respond to your feedback questions.
