That’s a poor example. I wouldn’t do that for a dentist since people go to the dentist. If you’re building a lead gen site specifically for rank and rent then go after businesses that service customers at their location and not where the customer comes to them. If it’s a dentist and you hide the address on GMB it’s obvious that it’s a lead gen site. Plus you can’t control citation sources where the address is shown, ie - yelp, yellowpages.
