Yes. Reviews are one of the strongest parts of what Google calls prominence, and a business with more recent, well-rated reviews will usually outrank a similar one with fewer. The count, the average, how recently they arrived and what people actually write all feed in. Reviews earn their keep twice, though, because the same star rating that lifts you into the map is what makes people choose you once you are there.
What Google has actually said about reviews
Google does not publish its ranking formula, but for local results it has been clearer than usual. Its own help page on local ranking lists three factors, relevance, distance and prominence, and says outright that "Google review count and review score factor into local search ranking". It goes further: "more reviews and positive ratings can improve your business's local ranking".
That is as close to a straight answer as Google gives on anything. Independent surveys of local SEO practitioners have placed reviews among the top three ranking factors for the map pack every year for the past decade, usually behind only the Google Business Profile itself.
What Google does not say is how much. In practice, reviews rarely lift a business from nowhere into the top three on their own. They tip close contests. Two garages in Dudley with similar sites and similar profiles will be separated by the one with 120 recent reviews at 4.7 over the one with 11 reviews at 5.0.
Which parts of a review matter?
Not all reviews carry equal weight, and it helps to know which characteristics Google appears to notice.
Quantity. More is better, but with diminishing returns. The gap between 5 and 50 is enormous. The gap between 300 and 350 is barely visible.
Rating. A high average matters, but a perfect 5.0 on a handful of reviews looks thin and, to many customers, slightly suspicious. A 4.6 across a hundred reviews reads as a real business with real customers.
Recency. A review from last week says the business is still open and still good. Fifty reviews that all stopped in 2022 say something else. Steady arrivals matter more than a big total.
Velocity. Forty reviews in a weekend followed by silence looks like what it usually is. A few a month, every month, is the pattern Google expects from a healthy business.
What people write. Google reads review text. A review that says "had my Invisalign done here, brilliant" helps a Hagley dental practice appear for Invisalign searches. A review that just says "great" helps less. You cannot script this, but you can make it easy for customers to describe what they had done.
Replies. Answering reviews does not directly move rankings, but Google has said it "shows that you value your customers", and businesses that reply tend to receive more reviews. It also gives you a chance to add detail: "Thanks Sarah, glad the kitchen in Kingswinford turned out well" tells Google and the next reader something useful.
Do reviews help beyond the ranking?
Ranking gets you seen. Reviews get you chosen, and the second effect is often larger than the first.
Say a search for "emergency plumber Stourbridge" shows three businesses in the map. One has 4.8 from 90 reviews, one has 4.2 from 30, and one has no rating at all. Most people ring the first without reading further. The third might as well not be there. Its position in the pack was worth nothing.
The same applies on your website. A visitor who sees real reviews with real names, linked to Google so they can check, has one less reason to hesitate. This is why we put reviews near the phone number and the contact form on the sites we build, rather than on a testimonials page nobody visits.
There is a third, quieter effect. AI answer engines and AI Overviews summarise what people say about businesses. A profile with detailed, specific reviews gives them something to summarise. A profile with six one-word reviews does not.
How do you get more reviews without breaking the rules?
The businesses with hundreds of reviews did not get them by luck. They asked, every time, in a way that made it easy. The rules are worth knowing because breaking them can get your reviews removed or your profile suspended.
Ask everyone. Google's guidelines prohibit "review gating", which means asking only the customers you think will be positive. Ask all of them and accept the occasional three-star.
Do not pay, discount or enter people into prize draws. Incentivised reviews are against the guidelines and are easy for Google to spot when they arrive in a batch.
Do not write them yourself, ask staff to, or buy them. Fake reviews are being removed in large numbers, and the UK's Digital Markets, Competition and Consumers Act now makes commissioning them illegal as well as against Google's rules.
Make the link short. Your Google Business Profile gives you a direct review link. Put it in a QR code on the invoice, in the job-complete text message, in the email signature.
Ask at the right moment. For a mechanic, the moment the customer collects the car. For a kitchen fitter, the day after the final visit, when the customer is still pleased and before they have found the one drawer that sticks. For a solicitor, when the matter completes.
Ask in person and follow up in writing. "Would you mind leaving us a Google review? I'll text you the link" converts far better than a line at the bottom of an email.
Should you reply to reviews, including the bad ones?
Reply to all of them, and reply to the bad ones first. A one-star review with no response looks like a business that does not care. A one-star review with a calm, factual reply that acknowledges the problem and offers to sort it looks like a business that does.
Keep replies short and specific. Thank the reviewer, mention something from their review, and sign off. Do not argue in public, do not reveal personal details, and do not copy and paste the same three sentences to everyone.
If a review is genuinely fake or breaks the guidelines, you can flag it through your profile. Google does remove them, but it is slow and it does not always agree with you. Reply to it anyway while you wait.
Do reviews on other sites count?
Google's own reviews carry the most weight for Google's own results, but they are not the only ones that matter. Reviews on Facebook, Trustpilot, Checkatrade, Yell and industry-specific sites all contribute to prominence, and Google sometimes surfaces them in the knowledge panel as "reviews from the web".
More importantly, your customers look at them. A solicitor is judged on Google and on the Law Society's ReviewSolicitors. A tradesperson is judged on Google and on Checkatrade or Which? Trusted Traders. Pick the one or two platforms your customers actually use, and send people to Google first.
A review routine for a small business
| When | Who | What | |---|---|---| | Job completed | The person who dealt with the customer | Ask in person, mention the text is coming | | Within 24 hours | Office or owner | Send the direct review link by text or email | | Within a week of a review arriving | Owner or manager | Reply, naming something specific from the review | | Monthly | Owner | Count new reviews, check the average, look for any that need flagging | | Quarterly | Owner or your SEO partner | Compare count and rating with the top three competitors in the map |
This is part of what we set up for clients on our local SEO work, and it was part of the routine behind Your Local Mechanic, where a rebuilt site, a properly completed profile and steady reviews took the Google rating from 3.6 to 4.3 in five months and calls straight from the Google listing up 137% year on year. The reviews were not the whole story, but the business would not have held its place in the map without them.
