For any search with a local intent (a trade and a city, or "near me"), Google shows three businesses on a map above the classic results. Those come from Business Profiles, ranked by relevance, distance and prominence. A complete profile with the right category, regular photos and answered reviews is the single biggest lever of local visibility for a service business.
The profile also feeds the entity Google holds for the company, which AI assistants reuse when asked for a provider in a city. Name, address and phone should match the website and the directories where the company is listed.
