Do you think this is only associated with GMB’s or also SERP results?Yes, it does apply. I can tell it based on my competitors. I have noticed that the strategy has changed, and more and more businesses are getting extra GMB listings associated with their company. They are getting away with it because Google thinks the new listing is a secondary "branch."
Now, the one with the most listings wins the most clients. Proximity is key.

That’s nice to hear, it seems my theory that individualized city pages would beat state wide pages is coming true.
