If your customer gives you five stars (they’re a promoter), you might want to include an additional request for a Google Review. Simply drop in the link to your Google Business page and add a message like, "We're so glad you had a great experience! Would you mind sharing your thoughts on our Google page?"
If your customer gives you one or two stars (they’re a detractor), consider a different message like, "We're sorry you didn't have a good experience. We appreciate you letting us know, so we can fix the problems you encountered." If you have a discount, free service or another way to possibly change their mind or ease their complaint, offer this as well.
Please keep in mind that the terms of service on some third-party review sites require that all customers be given equal opportunity to share their feedback, whether positive or negative. Read the terms of service of each site carefully before asking your customers to leave reviews on other sites.
To make a field visible to only certain customers depending on what they rated you, edit the message or redirect by clicking on it. In the Field Settings, under Field Visibility, select By Sentiment. You can then choose to only show the field to those who fall into each category.
