We measured every grocery store listing that ranks on Google Maps in 40 US cities. 796 listings. The typical one carries 153 reviews and a 4.2 rating. The part that surprised us: that number barely moves between the largest metros and mid-sized cities. What changes is how far below it you can still rank.
In plain terms: a mid-pack ranking listing has around 153 reviews and a 4.2 rating. The middle half of everything that ranks sits between 48 and 1,197 reviews, which is a very wide spread. And 73% ranking listings is rated below 4.5, so the rating is not the gate people assume it is.
Method. Google Maps results for “grocery store in {city}” across the 40 largest US cities, collected 1 September 2026, signed out, twenty results deep per city. 800 listings returned. 4 were removed because Google classifies them as something other than a grocery store, leaving 796. Of those, 759 display a review count. Sponsored listings are stored and counted but never averaged into these figures. Ratings and review counts are Google’s own displayed values. Rankings vary with the searcher’s exact position, so treat city-level figures as a benchmark rather than a forecast. Full methodology. Re-measured quarterly, and this block stops rendering if a reading goes more than 180 days stale.
The common advice is that Google will not rank you below 4.5 stars. Across 796 ranking listings, 27% sit at 4.5 or above. Which means 73% does not. The lowest rating we recorded on a listing that was ranking was 1.0.
That cuts both ways, and the second half matters more.
A high rating does not rank you. 9% of ranking listings are already at 4.8 or better. At that density, moving from 4.7 to 4.9 buys you almost nothing in position. It buys you something in conversion, which is a different and still worthwhile argument.
A dip does not remove you. If your trailing average slides to 4.4 you are in an unglamorous minority, not out of the results. That is worth knowing before you spend a quarter panicking about a rating instead of building review volume and fixing proximity, which are what actually separate positions here.
What the rating does is decide whether someone who sees you clicks you. Treat it as a conversion number, measure it like one, and stop treating 4.5 as a cliff edge.
We ran the identical measurement on supermarkets, same 40 cities, same day, same depth. It is the closest neighbouring category we have measured, which makes it the comparison worth drawing.
A ranking supermarket listing has a median of 338 reviews against 153 here. Its bottom quartile sits at 70 against 48. And that tail is closed: one in ten top-three supermarkets listings has 27 reviews or fewer, where the figure here is 12.
Read together, those numbers describe the opportunity. This category has the more permeable bottom of the two. A well-run business with modest review volume, a complete profile and the right proximity can hold a top-three spot here in a way its counterpart next door cannot. That gap closes as the city gets bigger.
You will read that sponsored listings sit above every local pack and swallow the clicks. We looked for them in all 40 cities. We found 4 sponsored grocery store listings, in 2 cities. The other 38 returned none at the moment we measured.
Two honest caveats. Maps ads are an auction and they turn over through the day, so one snapshot per city tells you where ads were running that morning and not much about the rest of the week. And a small paid presence is not the same as a small paid opportunity. A thin auction is usually an argument for testing it rather than avoiding it.
Straight from the collection, three large metros and three mid-sized. Each name links to its Google listing so you can check any row yourself.

Each of these is a separate discipline with its own measurement. Start with whichever gap is widest for you.
Proximity, categories and the profile fields that decide whether you appear at all. The 153-review median is the target this work is measured against.
The profile itself: hours, attributes, services, photos and the edits that quietly get reverted.
Rating is a conversion lever here, not a ranking gate. 9% of ranking listings already sit at 4.8 or better.
Getting from where you are to 153 reviews, with a monthly target per location and a realistic timeline.
Name, address and hours consistent everywhere they are published, so nothing contradicts your profile.
Rankings measured on a grid around each location, so you can see the radius you actually own.
What we actually run against the benchmarks above, rather than a generic local checklist.
| Work | Why it matters when the median is 153 reviews |
|---|---|
| Review velocity per location | Closing a gap from 48 reviews to the 153 median is a volume problem with a timeline attached. We set a monthly target per location from its own gap and track against it, not against a group average that hides your weakest site. |
| Rating as a conversion metric | Rating does not gate ranking in this category, so we stop reporting it as a ranking risk and start reporting it against calls and direction requests, where it actually moves. 27% of ranking listings are at 4.5 or above, which means the floor is softer than you have been told. |
| Category and attribute governance | Primary category, hours, attributes, services and the booking link. These are the fields customers filter on, and the ones that drift when staff edit profiles or Google accepts a third-party correction. |
| Proximity grid tracking | Rankings measured on a grid around each location. In a category where a quarter of mid-sized-city listings rank on 49 reviews or fewer, proximity is doing more of the work than volume, and a city-level number hides that entirely. |
| Duplicate and suspension watch | Duplicate profiles split your reviews between two half-dead listings. Suspensions in regulated categories are slow to reverse. Both are cheaper to prevent than to fix, and both are invisible until someone is watching for them. |
| Benchmarks refreshed quarterly | Every figure on this page is re-measured across 40 cities each quarter. Your targets move when the market moves, rather than when someone remembers to update a slide. |
Review count against 153, for each location separately. Group averages hide the one site dragging the network down, and in a multi-site group the spread between your best and worst location is usually wider than the spread between cities.
Category, hours, attributes, booking link. This is the cheapest work and the only part that moves in days rather than months. 79% of ranking listings are claimed, so an unclaimed profile is a genuine outlier.
A location 105 reviews below the median needs roughly six to nine months at a realistic request rate. Anyone quoting six weeks is either buying reviews or measuring something else, and bought reviews are a suspension risk.
City-level rank is too coarse to attribute results to. Set the grid baseline first or you will not know what worked, and you will spend the next quarter arguing about it.
The median ranking listing across 40 US cities carries 153, with the middle half between 48 and 1,197. That spread is the real answer: there is no single threshold. A quarter of everything that ranks does so on under 48 reviews.
In a smaller city, often yes. One in ten listings holding a top-three spot in a mid-sized city has 11 reviews or fewer. In a large metro that figure is 20. The mechanism is proximity rather than volume, and grid tracking will tell you which radius you already own.
Lower than you have been told. 27% of ranking listings sit at 4.5 or above, which means 73% does not, and the lowest we recorded was 1.0. Rating is not a ranking gate in this category. It decides who clicks you, not whether you appear.
441 of 796 ranking listings use Grocery store, and 109 use Convenience store. It is the default and switching away from it needs a real reason rather than a hunch about intent.
Less than supermarkets, on the same measurement. Supermarkets have a median of 338 reviews against 153 here, and a bottom quartile of 70 against 48. This category has a more permeable tail.
Profile and category work shows within days to a few weeks. Review volume is the slow part and it sets your ceiling. Faster quotes usually mean bought reviews, which is a suspension risk, or a different metric being reported.
Quarterly, across the same 40 cities, with the same query and the same depth. This block stops rendering if a reading goes more than 180 days stale, so a number here is never older than two quarters. Where a figure changed from a previous version it changed because the measurement changed, and we say so.
The free audit reads your live Google profile and puts your review count and rating against the 40-city benchmark for your category.
