Why a single rank number misleads you
Search your main keyword from your desk and you will probably see yourself near the top. That result is real, but only for that spot. Google’s local results weigh three things: relevance, prominence and distance. Distance is measured from the searcher, so the same business can sit in position 1 on its own street and position 14 a short drive away.
Incognito mode does not fix this, because it hides your history, not your location. A standard rank tracker that reports one position per keyword has the same blind spot. It gives you an average that hides the streets where customers cannot find you, which are exactly the streets you need to know about.
What block-by-block tracking actually is
Block-by-block tracking uses a geogrid: a square grid of map coordinates centred on your business. A local rank checker runs the same Google Maps search from each point and records where your listing appears. The result is a map of coloured cells, one per point, each showing your position for that keyword at that spot.
A 7×7 grid is 49 searches; a 13×13 grid is 169. Together they show your google map ranking as a shape rather than a number: a strong core around your address, and edges where competitors take over. You can try one on our free Google Maps rank checker page, which explains each part of the grid.
Pick three to five keywords customers actually use
Start with the searches that bring paying customers, phrased the way they type them. For a dental clinic that might be “dentist”, “dentist near me”, “teeth whitening” and “root canal treatment”. For a plumber, “plumber”, “emergency plumber” and “water tank cleaning”.
- Include your main service as a plain one- or two-word search.
- Add one “near me” version; it is how many people search on their phones.
- Add your most profitable service, even if it has fewer searches.
- Leave out your business name. You will rank for it everywhere, so it teaches you nothing.
Fewer keywords tracked every week beat a long list you check once. You can add more once the first set is stable.
Set the grid size and spacing to match your service area
The grid should cover the area your customers come from, and no more. Two settings decide that: how many points the grid has, and how far apart they are.
- Dense city centre: a 7×7 grid with points about 300 to 500 metres apart. Map packs change quickly when there are competitors on every block.
- Suburb or small town: a 7×7 or 9×9 grid with points about 1 kilometre apart.
- Service-area business (plumbers, cleaners, movers): a wider grid, up to 13×13, spread over the districts you actually drive to.
Bigger grids show more detail but cost more scans, so start with the smallest grid that covers your customers. Whatever you choose, keep the same centre, size and spacing for every scan. Changing them breaks the comparison.
Read the grid: colours, average rank and the edges
NearPinn colours every cell with the same four bands across the app:
- 1–5, green. You are in or right below the map pack. These blocks bring calls.
- 6–10, amber. Visible if someone scrolls. Close enough to win with work.
- 11–15, orange. Slipping out of view. Few customers scroll this far.
- 16–20, red. Effectively invisible here; 20 means not found at all.
Then look at three things, in this order:
- The share of green cells. This is your real footprint for the keyword, and the number most worth growing.
- The average rank. Useful for trend lines, but one red corner can drag it down, so never read it without the grid.
- Which edges turn red first. A red edge towards a neighbourhood you serve is a target. A red edge towards the motorway is not worth chasing.
If your own address is not green for your main keyword, fix relevance before anything else: primary category, services and description. Our guide on how to rank higher on Google Maps walks through that order.
Track on a schedule and log every change
One grid is a snapshot. The value comes from repeating it. Scan each keyword once a week on the same day, and keep a short log next to the results: “changed primary category”, “added 12 photos”, “replied to every review”, “competitor opened on Main Boulevard”.
After a month you can match changes to movement. If the green core grew two weeks after you fixed your categories, that change worked. If nothing moved after a burst of posts, spend the time elsewhere. This is the whole point of tracking block by block: it tells you which effort earned the result.
Reviews are usually the slowest lever and the one people skip. If replying is what falls behind, our Google review reply generator drafts replies in your voice so the log does not stall there.
Turn the grids into a search engine ranking report
Owners and clients do not want 169 numbers. A good search engine ranking report for local SEO fits on one page:
- The first grid and the latest grid for each keyword, side by side.
- Green cells then and now, and the average rank then and now.
- The two or three changes made in between, from your log.
- The next target: the edge or keyword you will work on before the next report.
NearPinn exports rank results as PDF reports, so an agency can send every client a monthly report without rebuilding it in a spreadsheet. See how the rank grid works on the home page.
Mistakes that make the data useless
- Moving the centre. Centre the grid on your verified address and leave it there.
- Changing grid size between scans. A 9×9 grid and a 13×13 grid cannot be compared cell for cell.
- Reacting to one scan. Rankings wobble. Act on a trend across two or three weeks.
- Tracking only the head keyword. “Dentist” may be fine while “root canal” is red everywhere, and that is where the revenue is.
- Chasing every red cell. Proximity sets a limit. Grow towards the areas you serve, not the whole map.
Frequently asked questions
- How often should I track my Google Maps rankings?
- Weekly is enough for most businesses. Rankings move with your profile changes, your competitors and Google’s updates, and a weekly scan of the same grid shows the trend without reacting to day-to-day noise. Scan again right after a big change, such as a new primary category.
- Why do I rank first when I search from my shop?
- Because distance is one of Google’s three local ranking factors. Searching from your own address puts you at the centre of your strongest zone. A customer two kilometres away sees a different map pack, which is why a geogrid checks many points instead of one.
- What grid size should I start with?
- A 7×7 grid is a good first scan for a single location in a city. Use a wider grid, up to 13×13, when your customers travel further or you serve a whole district. Keep the size and spacing the same afterwards so scans stay comparable.
- Is a geogrid the same as a normal rank tracker?
- No. A normal rank tracker reports one position for a keyword, usually from one location. A geogrid repeats the search from a grid of coordinates around your business and shows the position at each point, so you can see where you win and where you disappear.
