Google Places is something every dentist needs to be aware of. I am not sure what this new Hotpot feature will do but again you need to be aware of its existence and see what happens.
Hotpot takes all of Google Places‘ ratings and reviews features and adds a more personal touch. Currently, Place Pages mostly aggregate review data from sources such as Yelp. With Hotpot, users will be encouraged to rate and review businesses directly from their Google-linked profile.
