For local results this factor is confirmed. Google's Business Profile guide says local results are "mainly based on relevance, distance, and popularity", and that prominence reflects "how many websites link to your business and how many reviews you have"; there is "no way to request or pay for a better local ranking." Claim and complete your Business Profile, keep name, address and phone consistent with your site, and ask customers for reviews. Whether Google checks for an office address to judge brand strength in ordinary web results is unconfirmed.
