How to get customer reviews on google
Make sure your business is listed on google plus.
Ask your customers if they will do you a favor and write a review for your business.
It's important to use the word " favor " because people are more willing to do favors for people they like.
Ask them to write a review for you when they're at the peak of their happiness with your service. If you're an escrow officer, it's when they receive their check.
