When a file closes and a client provides us with glowing feedback, we respond by thanking them for their feedback and asking them to provide a Google rating or review. We have been doing this for about a month, and so far no one has provided any reviews or ratings. Likewise, we previously had customer survey at the end of files (to establish a NPS), but no one completed them... Are there magic words or a better time in the process to improve engagement?
What would make you WANT to leave a review if you were them? .... a future discount? knowing it helps the staff who helped you?
Without knowing what you sell, it's difficult to give you specific ideas. But here's an out-of-the-box example.... print simple business cards with instructions on the back that offer to share a secret password which activates a game you can play on Google search.... "Review us on Google Maps and then email us to get the secret word"... etc
