Map-grid rank tracking explained: why one "ranking" number misleads you

Map-grid rank tracking exists because "Where do we rank on Google Maps?" doesn't have one answer. A homeowner two blocks from your shop and one eight miles away can type the same search and see completely different companies. If your agency, or your own quick check, reports a single ranking number, you're seeing one point on a map that has dozens. This post explains how map grids work, how to read one, and the mistakes that make grids look better or worse than reality.

Why one ranking number misleads you

Google says it ranks local results on three things: relevance, distance and prominence. Distance means the searcher's location changes the results. That has a few consequences contractors run into constantly:

• You look great from your office. Searching "plumber" from your shop puts you close to the searcher, so you'll often show in the top three.
• Your customers aren't at your office. They're spread across your service area, and in the towns farther out, closer competitors have the advantage.
• Personal results muddy it further. Your own search history and the fact that you've visited your own profile can affect what you see.

So "we're #2 for AC repair" is only true for one spot, one device and one moment. It's not wrong, just incomplete in a way that hides most of what matters.

How map-grid rank tracking works

A map grid places evenly spaced points over your area and checks your position in Google's local results for one keyword at each point, as if a searcher were standing there.

• A 5x5 grid has 25 points. A 7x7 has 49. More points, more detail.
• Spacing sets how far apart the points are, which determines how much territory the grid covers.
• The center point is usually your business location, because that's where distance works in your favor and it shows how far your reach extends.
• Each point displays a position, commonly color-coded: green for top three, yellow or orange for the middle, red for low positions or not found.

The result is a picture of your visibility: a cluster of green around your shop that fades out as you move away, and where it fades tells you a lot.

How to read a grid

When you look at a grid, ask these questions:

1. How far does the green extend? Top-three positions are where the map pack shows you without scrolling, so that's where most calls come from.
2. Which direction is weak? If you're strong to the south and weak to the north, there may be a strong competitor north of you, or your site and profile may not signal that you serve those towns.
3. Do the weak areas matter? If the red is over a lake, a farm field or a town you don't serve, it doesn't matter. If it's over your best neighborhoods, it does.
4. What's the average? An average position across all points is a useful single summary, as long as you remember it's an average.

Tip: Count the top-three points as well as the average. Moving from 6 to 11 top-three points on a 25-point grid means homeowners in more of your area see you without scrolling. That's closer to what affects your phone.

Choosing keywords to track

Track the searches that bring in jobs, not vanity phrases:

• HVAC: "AC repair," "furnace repair," "HVAC company."
• Plumbing: "plumber," "emergency plumber," "drain cleaning," "water heater repair."
• Electrical: "electrician," "panel upgrade," "EV charger installation."

Avoid padding a report with long phrases nobody searches, like "best licensed residential HVAC contractor in [small town]." You may rank first for those, and it won't ring the phone. Three to five core keywords per company is usually enough. See our trade pages for HVAC, plumbing and electrical for examples of what we track.

Mistakes that make grids misleading

• Changing settings between reports. A different grid size, spacing, center point or keyword makes month-to-month comparison meaningless. Lock the settings.
• Mixing devices. Mobile and desktop results can differ. Pick one, usually mobile because that's where home-service calls start, and stick to it.
• Too-tight spacing. A grid that only covers a mile or two around your shop will look green and tell you nothing about your service area.
• Too-wide spacing. A grid covering places you don't serve will look red for reasons that don't matter.
• Cherry-picked keywords. If the only keywords tracked are ones you already win, the report is marketing, not measurement.
• Reading one grid as a trend. Results fluctuate. Look at the direction over several months.

Using grids to decide what to do next

A grid doesn't fix anything by itself, but it points you to the right work:

• Weak everywhere, even near your shop: start with relevance, meaning your categories, services and website pages. Our GBP checklist is the place to start.
• Strong near your shop, weak farther out: work on prominence (reviews, local links) and pages that genuinely cover outer towns.
• Weak in one direction: look at who's winning there and what they have that you don't.

This is the measurement behind our Maps Pack Program: a 5x5 mobile grid on three agreed keywords, same settings every month, and a written day-60 check against the baseline. For trade-specific context, see ranking on Google Maps as an HVAC company.

Takeaway

Stop asking "what do we rank?" and start asking "where do we rank, and is that area growing?" Pick three money keywords, run a grid centered on your business with fixed settings, save it as your baseline, and compare against it every month. If someone sends you a single ranking number, ask to see the grid behind it. A free baseline grid is part of our free audit.
