How local results are chosen, and what you can actually update
Maps and local Search weigh relevance, distance, and how well known the business is. The profile is how you keep that information accurate.
Based on Google's Tips to improve your local ranking on Google

When someone searches for a business or a place nearby, Google shows local results in Search and on Maps. A search like “Italian restaurant” on a phone is the everyday version of this. Google’s stated goal is to show the nearby business that person would actually want to visit. You cannot pay Google for a better local rank, and you cannot file a request for one. The details of the algorithm stay private on purpose.
Three factors Google names
Local results rest mainly on relevance, distance, and prominence.
- Relevance is how well the Business Profile matches the search. Complete, specific information helps Google understand what you do.
- Distance is how far the business is from the person searching. If they do not share a location, Google uses what it already knows.
- Prominence is how well known the business is. Links from other sites, review volume, and positive ratings all feed that picture. Well-known places are more likely to appear.
What to keep current on the profile
Verification tells Google you are allowed to represent the business. After that, accuracy matters. Incomplete or wrong details can keep the profile out of searches it should match. Google asks for a full address when customers can visit, hours including special hours, the right business category, and practical attributes such as parking or Wi-Fi.
Reviews are part of prominence and part of trust. Replying shows you read them. Photos and videos show what the business actually looks like and offers. Retailers in eligible regions can also list in-store products so people can see what is on the shelf.
Distance is not something a profile edit can invent. A business in one town will not outrank a closer match for a searcher across the region just by adding keywords. The work that is in your control is relevance and prominence: a true category, complete details, real photos, and a steady habit of responding to reviews. The website still matters, because links and the information on your own pages contribute to how well known and how well described the business is.
Paraline treats the Business Profile as part of the same loop as the website. We compare what the profile says with what the site says, and with the searches people use, so local results and the pages behind them describe the same business.
