Matagali Indian and Thai Restaurant
A great way to increase Google reviews is to ask. I know it sounds simple, but you'd be amazed at how many businesses don't. Especially after a customer has had a really great experience, that's the best time to ask for a simple review. If people are dining in, can you ask when the check is presented?
Some easy dialogue that can help, "As a local business reviews mean a lot to us. We would greatly appreciate your review on our Google page. Thank you and we look forward to seeing you again!"
As to how to rate higher, do you mean by getting more high-rated reviews?
