How Many Google Reviews Do You Need? Data by Industry
In short. There is no universal number: it depends on your industry and city. In our observatory of 1,800 Google Business Profiles in France, the entry threshold of the top 20 ranges from 44 reviews for movie theaters to 388 for restaurants, and the top 5 have a median of 738 reviews against 300 for positions 16 to 20, with the same 4.62 median rating. To raise your rating, the number of 5-star reviews needed is n × (target − current) ÷ (5 − target): 48 reviews to go from 4.3 to 4.5 with 120 reviews. Our free Google review calculator does the math for you.
Why the number of reviews matters
Google says it plainly on its page Tips to improve your local ranking: "More reviews and positive ratings can help your business's local ranking." Reviews fall under what Google calls prominence: "Prominence means how well-known a business is. Prominent places are more likely to show up in search results."
Local search experts agree. In the 2026 Local Search Ranking Factors survey by Whitespark, published November 6, 2025 and based on 47 local search experts, "Quantity of Native Google Reviews with text" ranks 9th among local pack factors and "Recency of Reviews" 11th.
Neither Google nor Whitespark gives a target number. That is why we measured it.
What 1,800 profiles show
Our observatory covers 1,800 Google Business Profiles in France, collected on September 25, 2026, in 9 industries and 10 large French cities. For each search, we recorded the first 20 results and their reviews.
The clearest result: rating does not separate the top of the results from the bottom, volume does.
| Positions | Median number of reviews | Median rating |
|---|---|---|
| Top 5 | 738 | 4.62 |
| 16 to 20 | 300 | 4.62 |
The top 5 have about 2.5 times more reviews than positions 16 to 20, with exactly the same median rating. Between two businesses that customers like equally, the one with more reviews tends to show up first. This is Google's "prominence" in numbers.
Thresholds by industry
The entry threshold below is the first quartile of reviews among profiles in the top 20: 75% of the profiles that make it into the top 20 have at least this many reviews.
| Industry | Reviews to enter the top 20 (1st quartile) |
|---|---|
| Movie theater | 44 |
| Bakery | 123 |
| Hair salon | 155 |
| Gym | 180 |
| Restaurant | 388 |
The gap is large: a restaurant needs almost 9 times more reviews than a movie theater to reach the same zone. The reason is competition. Restaurants are numerous and each one collects reviews from many daily customers; movie theaters are few and well spread out.
Read these numbers as a floor, not a goal. Reaching the threshold puts you among the profiles Google shows; climbing within the top 20 then takes more, toward the 738 median of the top 5.
The formula to reach a target rating
The second question is about rating: how many 5-star reviews to move from your current average to the one you want. The formula:
5-star reviews needed = n × (target − current) ÷ (5 − target)
where n is your current number of reviews. It assumes every new review is 5 stars.
| Current reviews (n) | Current rating | Target | 5-star reviews needed |
|---|---|---|---|
| 50 | 4.0 | 4.5 | 50 |
| 120 | 4.3 | 4.5 | 48 |
| 120 | 4.3 | 4.7 | 160 |
| 300 | 4.5 | 4.6 | 75 |
Note how the cost climbs as the target approaches 5: going from 4.3 to 4.7 costs more than three times the effort of going to 4.5, because the denominator (5 − target) shrinks. A target of 5.0 has no solution once a single lower review exists. The Google review calculator runs this formula with your own numbers.
How much one bad review costs
Volume is also insurance. The weight of each new review is roughly 1 divided by your total count, so a large profile barely moves.
| Profile | One new 1-star review | New rating |
|---|---|---|
| 10 reviews at 4.7 | −0.336 | 4.36 |
| 700 reviews at 4.7 | −0.005 | 4.69 |
At 10 reviews, one unhappy customer visibly damages your rating, which every future customer sees. At 700, the same review is invisible in the average. This is the strongest argument for asking every customer instead of hoping only happy ones will write: the more reviews you have, the more stable your rating becomes.
From threshold to monthly target
To turn the data into a plan:
- Find your threshold. Use the industry table as a reference, then look at the competitors who show up for your main search. Our Google Maps rank checker shows who ranks around your address.
- Compute the gap. Threshold or top 5 level minus your current count.
- Spread it over 6 to 12 months. A gap of 200 reviews over 10 months means 20 per month, about 5 per week.
- Convert into requests. Measure your own ratio of reviews per request over two weeks, then divide your weekly target by it. With a ratio of 10%, for example, 5 reviews per week means 50 requests per week.
- Make asking automatic. A fixed QR code and a direct review link sent after each visit. See our guide on how to get more Google reviews.
Reviews must stay genuine. Google states that "Offering incentives, like free or discounted goods or services, in exchange for customers to post reviews, change reviews, or remove negative reviews is considered fake & misleading content and is strictly prohibited."
What about replying to reviews?
We read 3,200 reviews across 320 profiles: 46% of profiles do not reply to any review, and the average response rate is 33%. We found no link between response rate and ranking, nor between response rate and rating.
So replying is not a shortcut to the top. It remains useful for the customers reading your profile before choosing, and for keeping a relationship with those who took the time to write.
Limits of this data
Our observatory covers France only, in 10 large French cities and 9 industries, on a snapshot dated September 25, 2026. US thresholds will differ, especially in smaller cities where competition is lower; what we expect to hold is the pattern, volume separating profiles at equal rating. These are correlations, not an experiment: they do not prove that adding reviews causes a higher ranking, only that higher-ranked profiles have more. The 10% request ratio in the plan is an illustration, not a measured figure: replace it with your own. The rating formula assumes all new reviews are 5 stars, which rarely happens; real progress will be slower.
Tracking your progress
The target is only useful if you check it every month against your competitors. In GMB Club, the all-in-one marketing platform for local businesses, local SEO tracking follows your Google Maps position on a grid of points around your address next to your review count, so you can see when the volume starts to pay off.

Frequently asked questions
How many 5-star reviews do I need to raise my Google rating?
Use the formula n × (target − current) ÷ (5 − target), where n is your current number of reviews. With 120 reviews at 4.3, reaching 4.5 takes 120 × 0.2 ÷ 0.5 = 48 five-star reviews, assuming no new lower ratings arrive meanwhile.
How many Google reviews does a restaurant need?
In our observatory of 1,800 Google Business Profiles in France, the entry threshold of the top 20 for restaurants (first quartile) is 388 reviews, the highest of the industries we measured.
Is the rating or the number of reviews more important?
In our observatory, the top 5 and positions 16 to 20 share the same 4.62 median rating, but the top 5 have a median of 738 reviews against 300. At equal rating, volume makes the difference.
Can I reach a 5.0 rating?
The formula has no answer for a target of 5.0: once a single review below 5 stars exists, no number of 5-star reviews brings the average back to exactly 5.0.
How much does one bad review hurt?
It depends on volume. One 1-star review takes 0.336 points off a 4.7 profile with 10 reviews, and 0.005 points off a 4.7 profile with 700 reviews.
