There is no fixed number. In low competition local markets 25 to 40 reviews with a 4.5+ average is often enough. In competitive metro categories (dentists, lawyers, restaurants) the median 3 pack business has 150 to 400 reviews and a 4.6+ average. Reply rate and recency matter as much as the raw count.
Owners ask this constantly. The real answer is not a magic number. It is whatever beats the median of the three businesses currently in the pack for your category in your radius. Here is how to figure that out and what most categories actually need.
How Google's local algorithm actually weighs reviews
- Review count (more is better, but with diminishing returns past about 500).
- Average rating (4.4 is the practical floor in competitive categories).
- Review recency (a steady drip beats a one off burst).
- Reply rate (Google has confirmed responding to reviews helps).
- Review keywords (mentions of your service or location in review text).
Industry medians we see in the wild
- Restaurants (metro): 250 to 600 reviews, 4.4 to 4.6 average.
- Dentists: 120 to 300 reviews, 4.7 to 4.9 average.
- Lawyers: 80 to 200 reviews, 4.7+ average.
- HVAC and plumbers: 150 to 400 reviews, 4.7+ average.
- Hair salons and med spas: 100 to 250 reviews, 4.7+ average.
- Rural or small town anything: 25 to 60 reviews can win.

How to get there in 90 days
Ask every customer within 24 hours of the positive moment. Reply to every existing and new review within 24 hours. Most businesses double their review count in a quarter just by closing those two loops.
Quality of replies still matters
Reply rate alone is a signal. But replies that echo back keywords ("glad you loved the deep tissue massage") quietly add long tail relevance. Generic "thanks!" replies miss this.
The shortcut
Most businesses fail at reviews on volume of asks and volume of replies, not strategy. Automate both and the algorithm rewards you within weeks. AutoReplyPilot handles the reply side end to end in your brand voice.
Frequently asked questions
Slightly, past 50 reviews. A natural mix sits between 4.6 and 4.9. Don't chase a perfect 5.0.
Indirectly. Google reads third party reviews as part of overall reputation signals but Google reviews carry by far the most weight for the map pack.
Yes, if your proximity to the searcher is closer or your category relevance is tighter. Reviews are one of three big levers, alongside proximity and category.
