Do Google reviews help SEO? What it means for dental practices
Google says reviews can help your local ranking. It does not say how much, and much of the advice online goes well beyond what Google has said. Here is what is confirmed, what UK dental data shows, and where reviews fit alongside everything else that decides whether patients find you.

Do Google reviews help SEO? For a dental practice, yes, mainly in local search: the map results that appear when someone searches "dentist" plus a town. Google's own guide to improving your local ranking says local results are mainly based on relevance, distance and popularity, and that "more reviews and positive ratings can help your business's local ranking." Reviews also help patients choose you once you are on the screen. What Google does not say is how much weight reviews carry or that review keywords matter, so this guide separates what is confirmed from what is guesswork, and shows where reviews fit with the rest of your search visibility.
What Google says about reviews and ranking
Google's local ranking guide names three factors. Its introduction calls the third one popularity, and the section explaining it is headed prominence:
- Relevance: how well your Business Profile matches what someone searched for.
- Distance: how far your practice is from the searcher. If the searcher does not share their location, Google uses what it knows about it.
- Prominence: how well known your business is. Google says this is based on information "like how many websites link to your business and how many reviews you have."
Reviews sit under prominence. Google also recommends replying to reviews, saying in the same guide that positive reviews and helpful replies can help your business stand out. And it says there is no way to request or pay for a better local ranking.
That is the confirmed part. Claims you will see elsewhere, such as that keywords in reviews push rankings up, that review recency is a fixed ranking factor, or that a set number of reviews unlocks the map pack, go beyond anything Google has published. Some may be partly true, but treat them as theories.

Map pack versus your website's rankings
It helps to separate two kinds of search result:
| Result type | Do reviews help? | What else matters most |
|---|---|---|
| Local pack and Google Maps | Yes. Google names review count and ratings as part of prominence | Distance, a complete and accurate profile, the right primary category, links and mentions |
| Ordinary website results | Google has not said that Business Profile reviews affect how your web pages rank | Useful content, a sound website, links from other sites |
For a dental practice, the map pack is where local searches such as "dentist near me" lead. That is why reviews matter so much to dental SEO even though they do little for a blog post's position.
What UK dental data shows
In our study of 1,489 UK places, run on 13 September 2026, we recorded the three practices in the local pack for "dentist" plus each place name: 2,493 practices. The median pack holder had 113 reviews. The bottom tenth had 12 or fewer, and the top tenth 556.
The bar depends on how crowded the town is:
| Practices competing in the town | Median reviews of a pack holder |
|---|---|
| 5 or fewer | 70 |
| 6 to 8 | 108 |
| 9 to 11 | 188 |
| 12 or more | 249 |
Two lessons follow. First, reviews are clearly part of the picture, since pack holders in busier towns tend to have more of them. Second, they are not a gate: one in ten pack holders got there with 12 reviews or fewer, which means distance, relevance and the rest of prominence carried them. Ratings are high across the board. The median pack holder's rating was 4.8, and 72% were at 4.6 or better, so a strong rating is normal rather than a way to stand out.
How many Google reviews do I need?
Enough to be in the same range as the practices currently holding the map pack in your own town. The national median is 113, but the useful number is local: look at the three practices in the pack when you search "dentist" plus your town, and note their review counts. Our guide to working out your review target walks through it.
Google review calculators, which tell you how many five-star reviews you need to lift your average, answer a different question. They are fine for ratings arithmetic, but they cannot tell you what your market needs.
Do Google reviews help your business beyond ranking?
Yes, and this may matter more than the ranking effect. Your review count and star rating sit next to your name in the map pack, so they shape which practice a patient taps. Review text answers questions patients care about: whether the team is kind to nervous patients, whether children are welcome, whether appointments run to time. Google's own help on getting reviews says they "can help your business stand out and give potential customers helpful info."
How does Google Reviews work for a business
- Patients leave a star rating and, optionally, text and photos on your Business Profile, through Google Search or Google Maps.
- Google moderates reviews against its policies, so a review can be held back or removed.
- You can reply to each review publicly from your profile.
- You cannot remove a review you dislike, but you can report one that breaks Google's policies.
- Google prohibits incentives for reviews and selectively asking only happy customers, under its fake engagement policy.
Does your star rating affect ranking?
Google says "more reviews and positive ratings" can help, so rating is part of it. In practice, ratings among dental practices that hold map places are bunched together near the top, with a median of 4.8 in our study, so a rating in that range keeps you in contention rather than lifting you clear. A falling rating is still worth acting on, because patients compare stars side by side before they choose.
The better response to a poor review is a calm, professional reply and a steady flow of new reviews from other patients, not an attempt to have it removed. Google removes reviews that break its policies, not reviews a business simply disagrees with.
Is there any benefit to leaving reviews on Google?
For patients, a review is a way to help other people choose a dentist and to give the practice honest feedback. For your practice, every genuine review adds to the information Google uses for prominence and to the evidence a nervous or new patient reads before booking. It is worth telling patients that plainly when you ask: their few sentences help someone else in the town find a dentist they can trust.
Reviews on other platforms
Patients also leave reviews on Facebook and Trustpilot. The NHS website used to host reviews of NHS dentists but retired that service in July 2025. Google's local ranking guide does not say these count towards your Google ranking, but patients read them, so keep an eye on them and reply where you can. Concentrate your asking on Google, because that is where the reviews sit next to your name in the map pack.
Reviews on your own website
Showing reviews on your site helps patients, but it does not earn you stars in Google's results. Google's review snippet documentation says that if a business controls the reviews about itself, its pages using LocalBusiness or Organization structured data are not eligible for the star review feature. That includes reviews embedded through third-party widgets. Show reviews for the reader's benefit, not in the hope of gold stars in search.
How to improve Google reviews the right way
- Ask every patient. In person at the end of a visit, then by text or email with your direct review link.
- Make it easy. One tap from the message to the review form.
- Do not filter. Asking only the patients you expect to be happy breaks Google's policy.
- Never offer anything in return. Google says incentives such as free or discounted services in exchange for reviews are "strictly prohibited". The CMA's fake reviews guidance covers the UK legal side.
- Do not script reviews. Google's policy says businesses should not request that specific content be included, so do not ask patients to mention particular treatments or your town. Google has never said it helps ranking either.
- Reply to all of them. Short, warm and without clinical detail. Keep each reply specific to what the patient said.
Is SEO still worth it in 2026?
For a dental practice, yes. Patients still search for a dentist by town and treatment, and Google still shows a map pack for those searches. What has grown is the number of places where you need to be visible, including AI Overviews and AI assistants, and it is reasonable to expect them to lean on the same kinds of information: an accurate profile, a useful website, mentions across the web and genuine reviews. Reviews are one of the few parts of that you can improve every single week.
What reviews will not fix
Reviews will not overcome distance, a wrong primary category, an incomplete profile or a website that does not mention the treatments people search for. A practice with far more reviews than its neighbours can still miss the map pack for searches made a few miles away, which is why a single ranking position can mislead, as our guide to map visibility by people, not points explains. Our guide to local SEO for dentists covers the other signals. Practice Radar's reviews race dashboard sets your review count and rating against the practices around you, which is a quick way to see whether reviews are really what is holding you back.
