A service-area business ranks on Google Maps from the single point where its hidden address sits, not evenly across the service area it lists. The further a searcher stands from that point, the lower the rank, in every direction at once. To measure the reach, centre a grid on the hidden address and space it to the drive radius.
What a service-area business is to Google
In Google’s terms, a service-area business visits or delivers to customers and does not serve them at its own address. A plumber, an electrician, a roofer, a cleaner, a locksmith, a mobile mechanic. The profile keeps the address for verification, removes it from public view, and lists a service area instead: up to 20 towns, postcodes or regions. Google asks that the whole area stay within about two hours’ drive, and it no longer accepts a radius drawn on the map. A business that does both, such as a showroom whose fitters travel, is a hybrid and shows its address alongside the area.
Two things follow. On the map, customers see a shaded area rather than a pin. In the ranking, nothing changes: the hidden address is still a point, and Google still uses it.
Google still ranks you from a point
Google ranks local results on relevance, distance and prominence, and describes distance as how far each business is from the customer who is searching. For a service-area business that distance is measured from the address Google holds on file. Hidden means hidden from customers, not from the ranking.
So a searcher 1 km from the plumber’s home sees the plumber as a near business, and a searcher 8 km away sees it as a far one, behind every plumber who lives nearer. The service area shading on the map has nothing to do with it. The rank behaves exactly as a storefront’s would if the shop stood at that address.
The service area setting does not extend your reach
The service area is a declaration: here is where I work. It helps a customer in a listed town know you will come, and it helps Google know what the business is. It is not a ranking radius. Listing a town 15 km away does not put you in the top 20 there. Your rank in that town is set by distance against the plumbers who sit in it and around it, and most of them are nearer to its searchers than you are.
That is the mechanism behind the most common service-area complaint, “I cover the whole county and I do not show up in half of it”. The profile is fine. The county is bigger than the rank can carry, and no setting changes that. A wildly large service area does nothing for the rank either. Why your business is not showing up runs through the other causes to rule out.
Why the grid fades evenly, and what to look for
A storefront’s grid is usually lopsided. A river, a ring road, a rival on the next corner or a dense estate to the north all bend the edge. A service-area business with few rivals nearby often gets a grid like the one above: clean rings, green in the middle, red at the rim, because distance is the one thing changing from point to point.
That makes the grid easy to read, and the thing to look for is a dent. A side where the green stops early is a side where someone else is nearer: a storefront with a real address in that neighbourhood, or another service-area business whose hidden address sits there. Click the weak point and see who holds the top 3. On a grid that draws every competitor in the top 20, the dent has a name.
Three other readings are worth taking off the grid:
- The top-3 radius. How far out you stay in the top 3. Compare it with your drive radius. The gap between the two is where you are driving to jobs that come from somewhere else.
- The keyword spread. “Emergency plumber”, “boiler repair” and “plumber” fade at different distances. Scan each one.
- The hidden rivals. Some trackers miss listings with no street address. A grid read by a real browser at each point sees them as a customer would.
How to set up the grid
Centre it on the hidden address. You know your own address even if customers do not; type it in. A grid centred on the town centre, or on a point inside your service area, measures the wrong thing, because the rings spread from the address, not from the town.
Space it to the drive radius. If you take jobs up to 20 km away, the grid should be about 40 km across. A 9×9 at 5 km spacing covers 40 km with 81 points; a 7×7 at 3 km covers 18 km for a tighter trade. A circle shape fits the even fade and skips the corners nobody calls from. Grid size and radius has the arithmetic.
Read it with a real searcher. RankShark Track takes each reading with a real browser located at that point, so a listing with a hidden address is seen as a customer standing there would see it, including yours and your rivals’. Grids run from 3×3 to 21×21 as a square, circle or hexagon, every competitor in the top 20 is drawn on the same grid, and 25 months of scans are kept.
What to do about the weak side
Distance cannot be changed. The address is where it is, and no setting moves the point you rank from. Relevance and prominence can be worked on, and for the far side of the grid they are what is left.
- A service page for that town. One page per area you want, saying what you do there, with the area’s own place names and real jobs described. It lifts relevance for searches that name the town, which is how many service-area searches are worded.
- Reviews that name the area. A review that says “fixed our boiler in Northfield” carries the place name into the profile. Ask customers on the weak side, and ask them to mention the job and the area.
- A second verified location, when it is a real office. A staffed office with its own hours in the far town gives Google a second point to measure from. A mailbox, a virtual office or an address you do not work from breaks Google’s rules and risks the profile, and it is not worth the rank.
Then accept some of the fade. At 20 km you will usually sit below the plumber who lives there, and that is how the system is meant to work. Measure whether you hold the top 10 at the edge, not the top 3. Why rankings change from street to street explains the same mechanism for a storefront.
The next step is one scan: run the free audit for your business and your main keyword, 49 points on a 7×7 grid, and find the side where the green stops early.
