On my google business listing for Southern Smiles. It doesn't display the reviews the same way it does with the other businesses. Instead of showing stars, it shows "1 review". Why is this?
1) Southern Smiles
2) 275 N Frontage Rd
Previously, it took 5 stars before reviews started showing. As of last February however, Google started displaying stars for businesses with 2 or 3 reviews. I even saw one with 0 reviews once (presumably Google was going off their 3rd party reviews on another site?)
Get another 2 or 3 reviews, you'll see the stars appear at some point in that process. You can make it much more straightforward when asking customers to leave a review by generating a review link. I like using this tool.
Here's the link for your business:
