You show up in the Google map results by having a complete Business Profile, reviews arriving steadily, your name and address and phone identical everywhere they appear online, and pages on your site about the towns you serve.

Distance from the searcher matters too and you cannot change that, which is why a business in Gilbert will struggle to appear for somebody searching in Scottsdale no matter what it does. Aim at the towns you can realistically reach.

The one owners neglect is consistency. If your address is written one way on Google, another on Facebook and a third on an old directory listing, Google trusts all of them slightly less. Pick one exact format and use it everywhere.
