The short answer
Google ranks local results partly by how close the business is to the person searching. That is why a business can appear in one area and vanish in the next. Distance cannot be changed, but relevance and prominence can, and they decide how far the business reaches.
Local results move with the searcher
When someone searches for a local service, Google does not show one fixed list. It builds the list for that person, at that moment, from where they are. Two people searching the same words a mile apart can see different businesses in the map results.
Google describes three main factors for local ranking: relevance, distance and prominence. Its own local ranking help page sets them out. Relevance is how well the business matches the search. Distance is how far the business is from the searcher, or from the place named in the search. Prominence is how well known the business is, judged from reviews, links, mentions and other signals.
So a business appearing near its office and fading further out is usually the distance factor doing exactly what it was designed to do.
Why the edge falls where it does
The point where a business drops out of the results depends on the competition. In an area with few similar businesses, Google may show the same business to searchers several miles away, because there is little else to show. In a dense area, other businesses closer to the searcher take those places, and the reach shrinks.
That is why rank tracking tools that check from a single point can mislead. A business can rank first from its own street and not appear at all from a postcode it serves every day.
What you can change
Distance is fixed by the business address. The other two factors are where the work goes:
- Relevance: the right primary category on the Business Profile, services listed in full, and a website with a clear page for each service.
- Prominence: a steady flow of genuine reviews, consistent business details across the web, and mentions or links from local sites.
- The website itself: a page about the area that says something specific, linked from the Business Profile where it fits.
Stronger relevance and prominence push the edge further out. They do not remove it.
What you should not do
Some fixes make things worse. Listing a fake address in a better location breaks Google's guidelines and can get a profile suspended. Adding town names to the business name on the profile has the same risk. Creating several profiles for one business is treated as spam.
How to see where you stand
Search for your main service from a few different places, or ask people in those areas to search and send screenshots. Note where the business appears and where it drops away. Then check the profile's performance data in Google Business Profile to see which searches lead to calls and direction requests. Our Google Business Profile work starts from that picture, and our answer on why a business is not showing on Google Maps covers the case where it does not appear at all.
