How many Google reviews do you need?

“How many reviews do I need?” comes up with almost every trade we talk to. The honest answer is that there isn’t a number. There’s a comparison, and a habit.

What Google says about reviews and ranking

Google ranks local results on three things: relevance, distance and prominence. Reviews are part of prominence. In Google’s words, prominence is “based on info like how many websites link to your business and how many reviews you have”, and “more reviews and positive ratings can help your business’s local ranking.”

Notice what that doesn’t say. There’s no threshold where you suddenly appear, and reviews are one factor among three. A firm closer to the person searching, or one that matches the search better, can rank above you with fewer reviews.

What we have seen

Luke and Dan’s had 5.0 stars from 91 reviews, and still ranked below four Swindon firms on “tree surgeon Swindon” in August 2026, one of them with a third of their reviews. Those firms were in Swindon; Luke and Dan’s are six miles out. In their own town they were 1st of 17 on 19 September 2026. Read their case study.

So the right question isn’t “how many reviews do I need?” It’s “how do I compare with the firms Google shows next to me?”

Work out your number in five minutes

1. Search your main job and town on Google Maps, the way a customer would: “roofer Chippenham”, “driveway cleaning Swindon”.
2. Write down the top three or four firms: their star rating and their number of reviews.
3. Note how recent their newest reviews are. Open each listing and look at the dates.
4. Your first target is the middle of that group. If the top three have 40, 85 and 210 reviews, getting to around 85 puts you firmly in the conversation.
5. Your ongoing target is a few new reviews every month, so your newest reviews are always recent.

Do this for each town you want work in. The numbers can be very different a few miles apart.

What we have seen

When we started with Swindon Transport & Recovery on 29 September 2026, the recovery firms already on the map in Swindon had between 59 and 425 Google reviews each. For a new firm, that’s the gap to close, firm by firm, not an abstract target. Read the case study.

Why recent reviews matter as much as the total

A firm with 200 reviews, the newest from last year, looks like a firm that’s slowed down or stopped asking. A firm with 60 reviews, three of them from this month, looks busy and current.

Customers read the newest reviews first. A steady trickle of new ones, every month, does more for you than a burst of twenty followed by silence. It’s also what you get naturally if you ask every customer at the end of every job, which is the method in how to get more Google reviews without begging.

How many five-star reviews to raise your rating

If your average is lower than you’d like, here’s the sum for how many five-star reviews it takes to reach a target:

Five-star reviews needed = reviews you have × (target − current rating) ÷ (5 − target)

Worked examples:

You have	Average now	Target	Five-star reviews needed
10 reviews	4.2	4.5	6
20 reviews	4.6	4.8	20
50 reviews	4.5	4.7	34
100 reviews	4.7	4.8	50

Two things jump out. First, the more reviews you already have, the more it takes to move the average, which is why the score settles down over time. Second, getting very close to 5.0 is hard: the closer the target is to five, the bigger the number.

What one bad review does

With only a few reviews, one unhappy customer moves the score a lot.

Say you have 30 five-star reviews, then get a one-star. Your average drops to about 4.87. To get the average back to 4.9 takes 9 more five-star reviews. To get it back to 4.95 takes 49.

That’s the case for asking every customer from the start: the more genuine reviews you have, the less any single one can move you. It’s also why replying calmly and helpfully to a bad review matters. The next customer reads your reply as much as their complaint.

Is 5.0 better than 4.8?

Not always. A perfect 5.0 from six reviews tells a customer much less than a 4.8 from 150. Some people are wary of a perfect score from a handful of reviews. Count and recency build trust; a score alone doesn’t.

A rough guide, if you want one

There’s no official number, but in our experience:

• Under 10 reviews: you’re easy to pass over. Getting to double figures is the first job.
• Around the middle of the firms next to you: you’re in the comparison, and other things (distance, category, your website, your photos) start to decide it.
• Above the firms next to you, with new reviews every month: reviews stop being the reason you lose a job.

For real figures by trade and town, we looked at the reviews of 2,762 UK trade firms Google shows first: how many Google reviews UK trades have.

How we do it, and why it works

When we take on a trade, the first thing we measure is exactly this: Google’s own list for their trade in their town, and their reviews against the firms around them, recorded with a date. Then a review request goes to every customer after every job, in your name, with your link, so the count rises steadily and the newest reviews stay recent. It’s part of the “Found” side of our work, alongside your listing, your website, replying to every enquiry and chasing every quote.
