Google doesn't publish a number, and the ranking studies I've read don't name one either. The closest thing to a benchmark is BrightLocal's 2026 survey of 1,002 US consumers, where 47% said they won't use a business with fewer than 20 reviews, so treat 20 as the floor for getting considered at all. Past that, keep new reviews coming in every month and answer each one, because customers filter for recent reviews and check whether you reply, and local search experts rate recency as a ranking factor.
Is there a minimum number of Google reviews you need?
Google sets no minimum for showing up, but customers have one, and the best survey figure on it sits near 20 reviews. In the same BrightLocal survey, only 9% said they'd use a business with five or fewer. The panel was American, so treat these figures as direction. Your competitors' counts tell you more. Search your main service and town like a customer would, look at the three businesses in the map results, and note how many reviews each one has and the date of its newest one. If they have several times your count, a customer comparing you side by side sees that gap first.
How do Google reviews affect your ranking on Google Maps?
Reviews feed what Google calls prominence, one of the three things it uses to rank local results, along with relevance and distance. Google's help page on local ranking says more reviews and positive ratings can help a business's local ranking. Whitespark's 2026 Local Search Ranking Factors survey, published in November 2025, asked local search experts to score ranking factors, and for the map results they put a 4 to 5 star Google rating at #6, the number of Google reviews with written text at #9, how recent the reviews are at #11, and new reviews arriving over time instead of in bursts at #14. Distance still counts. A business with 300 reviews across the city can lose a search to one with 40 down the street from the person searching.
Do reviews decide whether a lead calls you?
For a lot of people they do, because reviews are what they read right before they pick up the phone. In BrightLocal's 2026 survey, 97% said they read reviews for local businesses, and 68% said they'll only use a business rated four stars or higher, up from 55% the year before. 31% now want 4.5 stars or better. If you run ads, someone who sees one can search your name before calling, and if three reviews from 2022 are what they find, plenty of them will move on to the next name. Once they do call or fill out a form, how fast you get back to them decides the rest, which I covered in speed to lead.
Why do recent reviews count for more than old ones?
Because customers filter for them, and the experts in Whitespark's survey rate recency as a ranking factor too. BrightLocal found 74% of people look for reviews written in the last three months, and 32% look at the last two weeks, up from 20% the year before. A profile with 150 reviews and nothing new since last spring looks like a business that slowed down, even when it didn't. That should change how you ask. A one-time push that brings in 30 reviews in a month and then stops leaves you, three months later, with 30 reviews older than what most customers say they look for. Asking after every job keeps new reviews arriving at the pace you finish jobs, which is the pattern Whitespark's experts rated at #14.
Should you reply to every Google review?
Yes, and you're writing those replies for the next customer more than for Google. BrightLocal's 2026 survey found 89% of consumers expect owners to respond to reviews, 80% are likely to use a business that responds to all of them, and 42% are unlikely to use one that never replies. Half said they're unlikely to pick a business whose replies look templated. For ranking, replies count for little. Whitespark's experts put owner responses to most reviews at #122 for the map results, so the survey numbers above are the reason to write them. Google's own guidance asks owners to stay polite, keep deals and promotions out of replies, and never share a reviewer's private information. A reply that names the job ("thanks for having us out for the furnace swap on Tuesday") shows a person read the review, and the same thank-you pasted under 40 reviews is the templated kind half of customers hold against you.
How should you ask customers for a Google review?
Ask every customer in person at the final walkthrough, when they've just seen the finished work, then text them a direct link the same day. Google lets you create a short review link or QR code from your Business Profile, and a link that opens the review box directly saves them hunting for your listing. Name the job in the text so they know which visit you mean. One reminder a few days later is fine. After that, let it go. If texts already go out after each job, add the review ask to them. Ask the customer whose job had a hiccup too, since Google's policy bans selectively asking happy customers, and a review that says you came back and fixed something tells a reader more than another "great job." The same walkthrough is a good time to ask for a referral, which I wrote about in when referrals run out.
Can you pay for reviews or offer a discount for one?
No. Google's policy bans offering incentives "such as payment, discounts, free goods and/or services" in exchange for a review, and says fake engagement will be removed. The same policy rules out discouraging negative reviews or selectively asking for positive ones, which covers review gating, the setup where happy customers get sent to Google and unhappy ones get sent to a private feedback form. Reviews posted from several accounts by one person, or at one person's request, are banned as well. The law covers some of this too. In the US, the Federal Trade Commission's rule on consumer reviews, in effect since October 21, 2024, bans buying fake reviews and rewarding customers for reviews that take a particular side, positive or negative, and the FTC can seek civil penalties under it. In Canada, the Competition Bureau's March 2017 warning about fake online reviews named businesses that give customers incentives to leave positive reviews.
Do Google reviews affect whether AI tools recommend you?
Yes, and so do your reviews on other sites. BrightLocal's 2026 survey found 45% of consumers had used ChatGPT or another AI tool for local recommendations, up from 6% a year earlier. When Whitespark added AI search visibility to its ranking factors for the first time in the 2026 edition, the experts put the authority of the third-party sites hosting your reviews at #5, a 4 to 5 star Google rating at #8, and the number of different sites carrying your reviews at #11. Darren Shaw, who runs the Whitespark survey, wrote in the report that "you can't just send review requests to Google anymore." The wording inside reviews counts as well. In the same BrightLocal survey, 82% said they read AI-generated review summaries, which get built from what your customers wrote, so a review that names the service and the town gives that summary something specific to say.
Reviews before you spend on ads
Ads put your name in front of people who've never heard of you, and those people read your reviews before they call. If your profile is under 20 reviews or hasn't had a new one in months, sort that out alongside the ad budget (I covered the budget side in how much you should spend on ads). If you want to talk through whether your business is ready for ads, book a call.
