You checked Google from your shop and saw yourself near the top. Nice. But your customer isn’t standing in your shop. They might be three miles away, and Google may be showing them a different list.
Here’s what we mean. We searched “plumbers in salinas” once, from one spot. Then we ran the exact same search from 25 spots across Salinas with our geo-grid tracker. The answers didn’t agree.
One search, one spot
The graphic at the top is a single Google search for “plumbers in salinas” on September 23, 2026. It’s a valuable search: about 1,000 people a month make it, and advertisers pay almost $20 a click. No wonder two businesses paid to be on top. Here’s what showed up:
- Two ads first. Alvarez Plumbing paid for a web ad at the very top, and Family Home Plumbing Services paid for the first spot in the map pack.
- Three free map pack spots: Alvarez Plumbing (4.9 on 263 reviews, 45+ years), My Plumber Inc. (5.0 on 189 reviews, 7+ years) and MZ Plumbing (5.0 on 102 reviews, 25+ years).
- An AI Overview that named the same three free listings and skipped both ads.
Two things jump out. First, Alvarez shows up twice: once as an ad and once in the free listings. Paying and ranking are separate contests, and Google says there’s no way to pay for a better local ranking.
Second, MZ Plumbing made the top three without a website button and with a 5 PM closing time, while the other two show open 24 hours. One search can’t tell you why. That’s the real problem with one search: it’s one searcher, in one spot, at one moment.
So let’s run it 25 times.
What a geo-grid is
A geo-grid runs the same Google Maps search from many points on a map and records who ranks at each one. For this scan, our tracker dropped 25 points in a 5 by 5 grid over Salinas, 2.5 km (about 1.5 miles) apart. Together they cover a square about 10 km (6 miles) on each side, from Santa Rita down to Spreckels Junction and from Boronda across to Williams Ranch.
At every point it searched “plumbers in salinas” and recorded the top 20. Three terms you’ll see:
- Point: one simulated searcher’s location.
- Average rank: a business’s average position across the points where it showed up.
- Top 3 hits: how many points put it in the map pack’s top three.
Why bother? Because Google says distance, meaning how far a business is from the person searching, is one of the three main things local results are based on (Google Business Profile Help). When you check Google yourself, you’re seeing one point: usually your own shop, which is often your best-case view.
Reading the grid
Alvarez Plumbing across the grid Found at all 25 points and in the top 3 at all 25, with an average rank of #1.1. That’s what ranking well actually looks like. My Plumber Inc. across the grid #2 in the single search, but in the top 3 at only 12 of the 25 points, with an average rank of #3.4. Water Heaters Plumbing & Drains Not in the single search’s top 3, yet the third-best average rank on the whole grid (#5.2). 25 searches, one map Each X is one simulated searcher: 25 points, 2.5 km (about 1.5 miles) apart, covering a 10 km square over Salinas. The inspected point A spot in North Salinas. The panel on the right shows the actual top results from this one point. #1 here: Alvarez Plumbing 4.9 on 263 reviews. The same leader as the single search. #2 here: At Your Service Plumbing 5.0 on 37 reviews. A service-area business, so no street address shows. Google allows that for businesses that go to their customers. #3 here: CO Plumbing Salinas 4.8 on only 22 reviews, yet third at this point, above a business with 996. #4 here: Roto-Rooter 4.7 on 996 reviews, by far the most, and still fourth. Reviews help, but they’re not the whole story. #5 here, and who’s missing Smith & Sons Plumbing, 5.0 on 7 reviews. My Plumber Inc., #2 in the single search, isn’t in the top 5 at this spot. 
Rankings shift by searcher location. Colors mark visible signals, not Google’s scoring.

The top row is the scoreboard: who did best across all 25 points. The map is the grid itself, one X per search. The panel on the right is the full result from one of those points, the one circled in North Salinas.
What the grid revealed
Alvarez Plumbing is the benchmark. It was in the top three at all 25 points, with an average rank of #1.1. That’s what ranking well actually looks like: not first from your own counter, but near the top everywhere a customer might be.
My Plumber Inc. is weaker than one search made it look. It was #2 in the single search, but in the top three at only 12 of the 25 points, with an average rank of #3.4. At the inspected point in North Salinas, it isn’t even in the top five.
Businesses you didn’t see can be winning. Water Heaters Plumbing & Drains wasn’t in the single search’s top three at all, yet it had the third-best average rank on the grid (#5.2). And MZ Plumbing, third in the single search, made the top three at 10 of the 25 points.
Paying for the top spot isn’t the same as ranking. Family Home Plumbing Services, which bought the first map pack spot in the single search, didn’t show up in the free top 20 at any of the 25 points.
Reviews aren’t everything. At the inspected point, Roto-Rooter has 996 reviews and sits at #4, while CO Plumbing Salinas has 22 reviews and sits at #3. Google says more reviews and positive ratings can help your ranking, and they do, but relevance and distance weigh in too.
We double-checked that inspected point with a second, independent data source the same day. It came back with the exact same top five, in the same order.
What a grid can’t tell you
A grid is a measurement, not a verdict on why. A few honest limits:
- It simulates searchers; it isn’t real traffic. Each point shows what a customer standing there would likely see, not what real customers actually saw.
- It’s one day. Rankings move day to day. That’s why every scan should be dated and run again over time.
- It doesn’t say why. The grid shows where a business wins and loses. The reasons still come down to relevance, distance and prominence, and nobody outside Google knows exactly how they’re weighed.
- Closest doesn’t always win. Alvarez made the top three even at the far corners of the grid, several miles from its address. Distance matters, but it isn’t the only thing.
- No address doesn’t mean no business. Two of the top five at the inspected point are service-area businesses, so no street address shows. That’s normal for plumbers: Google lets businesses that go to their customers list a service area instead.
How to move your grid
You can’t pay your way up the free listings, but you can work on the three things Google says it uses:
- Relevance: the right primary category, every service listed on your Google Business Profile, and a website with a real page for each service.
- Distance: you can’t move your shop, but you can make sure your profile’s service area matches where you actually work.
- Prominence: steady, detailed reviews, plus being mentioned and linked by other local sites. Google says prominence includes how many websites link to your business and how many reviews you have.
We cover each of these in the 3 pillars of local SEO, the map pack itself in how to read the Google map pack, and the whole results page in how Google Search works.
For the website side of relevance, our Search Console lesson shows how to check that Google has your service pages at all.
Summary
One Google search shows you one spot. A geo-grid shows you the whole map: where you win, where you’re weak and where you don’t show up at all. In this Salinas scan, the business that looked second from one spot made the top three at fewer than half the points, a business you’d never have noticed had the third-best average, and the one that paid for the top spot didn’t rank for free anywhere.
