Almost every small business owner we talk to is chasing the wrong number. They're trying to get to a 5-star average, which feels clean and motivating but isn't actually what Google rewards.
The 3-pack on Google Maps, that little stack of three businesses that shows up at the top of any local search, is decided mostly by two things: how many reviews you have relative to your nearest competitors, and how recent those reviews are. Star rating matters at the margins, but it almost never determines who's in the 3-pack and who's a scroll away.
Here's a practical breakdown of how many you actually need, by category, and what to do if you're behind.
The metric that matters
Aim to beat the lowest-ranked of your local top 3 by at least 20% on review count, with steady recent activity. That puts you in striking distance.
1. Why a star average isn't the metric
Google's map pack ranks businesses on three signals it talks about publicly: relevance, distance, and prominence. Reviews live inside "prominence", but they're only one of several prominence signals.
That said, in densely-populated categories, reviews are the single biggest lever you can pull. The trick is that Google doesn't score "5.0 stars" as automatically better than "4.7 stars". It scores how trustworthy your overall signal is. A business with 12 reviews at 5.0 looks weaker to the algorithm than a business with 184 reviews at 4.7.
The data backs this up. In nearly every category-and-location pair we've audited, the 3-pack winners aren't the highest-rated businesses. They're the ones with the most reviews andthe most consistent activity in the last 12 months.
2. The metric that actually matters: relative volume
Forget the star number. The number to chase is "reviews relative to my top 3 competitors". Specifically:
- Search the term you want to rank for, from the area you want to rank in.
- Note the review count on each of the top 3 results.
- Match or beatthe lowest-ranked of the top 3 by at least 20%, and you're likely in striking distance.
That's the entire framework. Whatever your category, find your local 3-pack, look at their review counts, and aim to be at least as loud.
This is also why nationwide review-count benchmarks ("every business needs 50 reviews") are mostly useless. Reviews are local. A café in regional Bendigo competing against another 3-review café needs much less than a Melbourne CBD café competing against eight 200-review competitors.
3. Rough benchmarks by category
That said, owners want a starting point. Here's what the top of the 3-pack tends to have in metropolitan Australia, based on what we've audited across our clients and their competitors. Treat these as the floor, not the ceiling.

Trades reviews often include photos of completed work, which signal trust to both Google and prospects. Dental + cleaning categories have lower volumes but a near-perfect rating matters more there than in higher-volume retail.
4. The recency lever (the one most owners miss)
A business with 80 reviews in the last 12 months will almost always out-rank a business with 200 reviews if all 200 of those are from 2020. Google reads recency as "this business is still active, still serving customers, still real".
Practically, this means two things:
- Old reviews lose weightover time. A 5-year-old review is barely contributing to your rank now. It still shows up on your profile, but Google's algorithm has discounted it heavily.
- Steady velocity beats batches. Ten reviews a month every month is more powerful than 50 reviews in one month and zero for the next four.
This is why the businesses we've helped see the biggest map rank gains aren't the ones we've helped get the most reviews. They're the ones we've helped get the most consistent reviews. The map heatmap fills in green from the centre outward when the recency stays high.
5. The maths on overtaking #1
Say you're currently sitting at #4 in your local 3-pack search, with 35 reviews. The #1 business has 110 reviews. The #3 business has 60.
To realistically overtake them, here's the rough plan:
- Match #3: you need 25 more reviews to be in striking distance of position 3.
- Beat #3: 30 more reviews, plus active velocity (5 to 8 new ones per month going forward, never letting up).
- Pass #1: 80 more reviews if their growth has plateaued. More likely you'll need 40 to 50 more plushigher monthly velocity than them, since they'll keep gaining slowly. The recency lever is what closes the gap.
At a healthy ask rate (say, 30% of customers leaving a review when prompted), 30 new reviews is roughly 100 customer interactions. For most service businesses that's 4 to 8 weeks of asking every customer.
6. What to do if you're starting from scratch
If you have under 10 reviews, the math above sounds heavy. It isn't. New businesses move up faster than established ones because Google rewards fresh activity heavily.
Practical first month:
- Verify your Google Business Profileif you haven't. Half the businesses we audit have unclaimed profiles.
- Set up a single wayto ask every customer for a review (SMS works best for service businesses, email second). Don't ask haphazardly.
- Start with your warmest customers first. The ones who'd already say nice things if you bumped into them. Get the first 10 in two weeks.
- Reply to every review within 24 hours, in your actual voice. (We wrote a whole piece on why templated replies hurt.)
7. The takeaway
Star average is a vanity metric. Review count relative to your local competitors, plus how recent those reviews are, is the real ranking lever. Search the term you want to rank for, look at the top 3, count their reviews, and build a plan to match the lowest of the three with at least 20% more recency.
Most owners are surprised by how attainable that is when they see the actual numbers instead of guessing.
