The impact of Google reviews on local SEO
When someone searches "dentist near me" or "garage in Getafe", Google doesn't return a neutral list: it ranks the businesses on the map according to criteria it partly documents itself. Reviews are among those criteria. This article separates what Google states explicitly from what's consensus observed by the SEO industry, and from what's outright myth. Repliq, the tool that syncs your Google Business Profile reviews and generates AI replies, exists precisely because managing those reviews is the part that gets abandoned the most.
How do reviews impact local SEO?
Google documents that review count and score contribute to prominence, one of the local-result criteria alongside relevance and distance. Replies are also public, and Google recommends using them to show that you value feedback. That does not make every reply, keyword, or activity pattern a confirmed ranking factor, and it cannot support a promise of a specific position.
The three criteria Google does document
Google Business Profile's official help documentation describes local ranking with three combined factors: relevance, distance, and prominence. For a detailed explanation of these three factors and nine additional factors the industry has inferred, see the complete Local Pack strategy guide. Here we focus specifically on how reviews impact these criteria.
- Relevance: your category and profile data: how well your listing matches what the person searched for. Filling in category, services, and description helps here.
- Distance: geographic location: how far you are from the search point or the stated area. It's the factor you have the least control over.
- Prominence: where reviews fit: how well-known the business is. Google expressly states that the number of reviews and the score influence local ranking within this factor.
That mention is the starting point: reviews aren't a local SEO trick, they're a declared component of the prominence criterion. What Google doesn't publish is the exact relative weight of each element, so any specific percentage you find out there is a third-party estimate, not official data.
Quantity: how many reviews you actually need
There's no universal magic number, because what counts is your volume relative to the competitors that show up in your same search and area. If the top three results in your category have 40 reviews, having 80 gives you a comparison point; it does not guarantee that you will outrank them. The practical way to set a target is to search for your main service from the area you want to rank in and note how many reviews the three businesses in the map pack have.
Frequency and recency: the flow matters more than the spike
There is no public review frequency that guarantees a better position. For a deciding user, the date of the last review is visible context: a complaint from three weeks ago is more recent information than one from 2021. Turning review requests into an operational habit, rather than a one-off campaign, helps keep information current without creating artificial spikes.
The review text: keywords you don't write yourself
Some local SEO practitioners infer that review text may add relevance context when several customers spontaneously mention a service or area, but Google has not confirmed that mechanism or its weight. Treat it as a hypothesis, not a guaranteed lever. In any case, you must not dictate what a customer writes or suggest phrases, because that can create artificial reviews and violate Google's policies. Ask for feedback about the real experience and let each customer describe it in their own words.
Response rate: what Google explicitly recommends
Google explicitly recommends replying to reviews because doing so shows that you value customers and their feedback. There is no public confirmation that response rate is a direct ranking factor. Replies are part of the public conversation a person may read before contacting you; measure that effect with your own enquiry and conversion data instead of presenting it as a ranking guarantee.
Factor summary
| Factor | Evidence | What to do |
|---|---|---|
| Number of reviews | Cited by Google in its official help | Compare against the top 3 in the map pack and keep asking continuously |
| Average score | Cited by Google in its official help | Fix the causes of repeated complaints, not just reply to them |
| Recency / frequency | Industry consensus + direct effect on the user | Steady monthly flow instead of one-off campaigns |
| Text keywords | Industry consensus, not confirmed by Google | Ask for the review right after the specific service, without dictating content |
| Response rate | Recommended by Google; direct effect not confirmed | Reply to positive and negative reviews |
Three myths worth dropping
"You need a perfect 5.0." A flawless average with dozens of reviews feels less credible to many users than a high average with a criticism or two well answered. Absolute perfection raises suspicion of bought reviews.
"Buying reviews speeds things up." On top of violating Google's policies and exposing you to review or profile removal, in several countries advertising based on fake reviews is classified as an unfair commercial practice.
"Reviews are everything." Distance from the search point and the consistency of category and listing data still carry weight. A listing with the wrong category won't rank well no matter how many reviews it accumulates.
A five-step action plan
Audit your starting point: number of reviews, average, and date of the last one, against the top three results for your target search.
Choose a request channel you can sustain every day (QR at the counter, message after the service) instead of a one-off campaign.
Aim to reply to positive and negative reviews, including five-star ones, with a consistent tone and without literally copy-pasted templates over and over.
Every month, review which reason keeps repeating in negative reviews and fix the operational cause, not just the public reply.
Measure again after a period that fits your volume and market: use several weeks or months of comparable data, not one isolated query or a universal timeline.
Where Repliq fits in

Frequently asked questions
Do Google reviews influence local ranking?
Yes. Google states in its Business Profile help documentation that local ranking is based on three criteria, relevance, distance, and prominence, and expressly mentions that the number of reviews and the score are part of prominence. Reviews aren't the only factor, but they're one Google itself documents.
Is it better to have lots of reviews or a great score?
Neither on its own. A high score with very few reviews conveys little evidence, and lots of reviews with a low score push customers away even if the profile is visible. The practical goal is sufficient volume for your industry with a high average sustained over time.
Does replying to reviews improve local SEO?
Google explicitly recommends replying to reviews in its documentation for businesses, noting that engaging with them shows you value customers. There is no public confirmation that replying is a direct ranking factor. The reply remains visible to future readers and may affect their perception, but that effect should be measured with the business's own data rather than assumed.
Does the recency of reviews matter?
The date is visible context for someone viewing a listing, but Google does not publish a universal rule that turns recency or a specific frequency into a ranking improvement. Use an honest, sustainable review-request process and measure perception and conversions without attributing every change to cadence alone.
Do the words customers use in reviews affect search?
Some local SEO practitioners treat it as a possible context signal, but Google has not confirmed that review words are a ranking factor or published their weight. Never dictate what a customer should write: ask for feedback about the real service and let them describe it naturally.
What's more important for local SEO: number of reviews or star rating?
Both are visible to customers and Google, but there is no universal combination or public minimum. Compare volume, score, recency, and replies with the listings competing for the same search, and do not promise a position based on a threshold.
How long does it take to see the impact of actively asking for reviews?
There is no universal timeline or guaranteed ranking improvement. Measure volume, recency, score, replies, and conversions over several weeks or months, using the same area and comparable queries.
Should I invest in Google Ads before improving reviews?
It depends on the goal and budget. Advertising and organic local results are separate systems: improve the listing experience and information first, then measure ads by their own conversions without assuming that one changes the other's ranking.
Do Google reviews also affect whether an AI assistant (ChatGPT, Perplexity, Google AI Overviews) recommends my business?
There is no public confirmation of one mechanism by which AI answers use or rank Google reviews, and each product may use different sources and criteria. Keep business information accurate and cite only what you can verify; do not treat reviews, activity or this guide as a guarantee that an assistant will recommend your business.
