Ask every guest, not just the happy ones, with a direct Google review link or QR code on the bill folder, receipt and follow-up message. Reply to every review. Never offer a discount, free dish or prize for a review, never ask for five stars, and never let staff pressure guests at the table.

Quick answer
- Google allows you to ask for reviews and to share a link or QR code that opens your review form.
- Google bans incentives (discounts, free food, prize draws), asking only happy guests, and pressuring guests on the premises.
- The biggest lever is consistency: the same polite ask, at the same moment, on every bill.
- Reply to reviews, good and bad. Google recommends it, and future guests read the replies.
- More reviews and good ratings can help your local ranking, according to Google, but they are not the only factor.

Is it allowed to ask guests for Google reviews?
Yes. Google’s own help page, Tips to get more reviews, tells businesses to remind customers to leave reviews and suggests sharing a Google link or a QR code that opens the review form. Google’s Maps content policy also says merchants are allowed to “solicit or encourage the posting of content that does represent a genuine experience, without offering incentives to do so or attempting to influence the rating or the contents of the review.”
So the question is not whether you can ask. It is how you ask. The line Google draws is simple: you can ask for an honest review, but you cannot pay for it, filter it, script it or pressure someone into it.
What does Google ban when restaurants ask for reviews?
These come straight from Google’s Maps user-generated content policy on fake and misleading content. Restaurants get caught by most of them without meaning any harm.
| Not allowed | What it looks like in a restaurant |
|---|---|
| Incentives of any kind | “Show us your review and get a free dessert,” 10% off your next visit, a lucky draw for reviewers, a free drink for a check-in plus review. |
| Asking only happy guests | Staff only hand the QR card to tables who said the food was great, or a tool that sends unhappy guests to a private form and happy ones to Google. |
| Pressure on the premises | A server standing at the table while the guest writes the review, or not bringing the bill until the review is posted. |
| Asking for specific content | “Please mention Khun Nok by name” or “please write that our tom yum is the best in Bangkok.” |
| Review targets for staff | Asking each server to collect a set number of reviews, or reviews that name them. |
| Conflict of interest | Owners, staff, family or your agency reviewing the restaurant; reviewing a competitor. |
| Paying to remove a bad review | Offering a refund or voucher if the guest deletes or changes a negative review. |
Google says content posted because of an incentive “will be removed from Maps,” and that unusual volumes or patterns of reviews can be treated as rating manipulation. Its tips page adds that offering incentives is “strictly prohibited” and links to restrictions for policy violations. Losing a batch of reviews you worked hard for is the mild outcome. Restrictions on the profile are worse.
Staff review targets are the one that surprises owners most. A friendly competition for the most reviews feels harmless. Google lists it by name as something merchants must not do.
Why do Google reviews matter for a restaurant?
Two reasons. First, guests read them before they book or walk in. Second, Google says on its local ranking page that prominence takes into account “how many reviews you have,” and that “more reviews and positive ratings can help your business’s local ranking.”
Reviews are one input among several. Relevance and distance still matter, and a weak profile with a pile of reviews will still underperform. I covered those in the earlier articles on setting up your Google Business Profile and why you are not showing up on Maps.
How do you get more Google reviews, step by step?
This is the system we put in place for restaurant clients at Markedine. None of it needs paid software.
- Get your review link. In your Business Profile, use the option to ask for reviews and copy the short link Google gives you. Google’s tips page explains how to create the link or a QR code.
- Make a QR code from that link. Test it on two phones, one Android and one iPhone, while signed out of the owner account.
- Put the ask where every guest sees it. A small card in the bill folder, a line on the printed receipt, a table talker, and the takeaway bag sticker. The same words everywhere.
- Use neutral wording. “Tell us how we did on Google” is fine. “Love us? Give us 5 stars!” asks for a rating and only targets happy guests.
- Brief the team once. Staff can mention the card when they bring the bill to every table. They do not wait while the guest writes, do not ask for stars, and do not ask anyone to name them.
- Follow up where you already talk to guests. If guests booked through LINE, email or a booking system, add the same link to the thank-you message sent to everyone, not a filtered list.
- Reply to every review within a couple of days. Short, specific, human. Fix what the bad ones point out.
- Check the numbers monthly. Count new reviews per month and look at what they mention. Patterns tell you what to fix in the kitchen and on the floor.
At Markedine our Google Engine service answers every review within 48 hours and uses review-ask artwork such as table talkers and bill-folder inserts. On our Google Engine page we published an unnamed restaurant whose reviews went from 5 to 25 a month. That is one restaurant, alongside other changes to its profile, not a promise for yours. What it shows is that a steady, honest ask adds up.
What should the review card actually say?
Keep it short and neutral, in the languages your guests read. For a Bangkok restaurant that usually means Thai and English, sometimes Chinese or Japanese too.
| Use this | Avoid this |
|---|---|
| “How did we do? Tell us on Google.” + QR code | “Give us 5 stars on Google!” |
| “Your honest review helps other diners find us.” | “Review us and get a free drink.” |
| “Scan to review us on Google Maps.” | “Mention your server’s name in your review.” |
| “ช่วยรีวิวร้านเราใน Google ได้ไหมคะ/ครับ” | A card only given to tables that look happy. |
A useful test: if you would be comfortable showing the card to a Google reviewer, it is fine. If it promises something or tells the guest what to write, change it.
What about review-gating tools and “happy or unhappy” screens?
Some feedback tools first ask the guest whether they were happy, then send happy guests to Google and unhappy ones to a private form. That is selective soliciting of positive reviews, which Google’s policy says merchants must not do.
Private feedback is still worth collecting. Just give every guest the same choice: here is a private form for the manager, and here is the public Google link. Let them pick.
How should you respond once the reviews arrive?
Google recommends replying. Its tips page says to keep replies professional, short and relevant, not promotional, and to protect the reviewer’s privacy. For negative reviews it suggests acknowledging mistakes, explaining limits honestly, apologising where it is right, and asking the guest to contact you privately for anything complicated.
Do not offer a voucher in exchange for changing the review. That is an incentive for a revision, which Google’s policy also bans. You can fix the problem and invite the guest back; whether they update the review is up to them.
I have a separate article on replying to bad reviews, with templates.
What can you do about fake or unfair reviews?
If a review breaks Google’s content policies, for example it is spam, off-topic, hateful or from someone who was never a guest, you can flag it. Google’s tips page links to the reporting steps. A review that is simply negative but describes a real visit respectfully is allowed, and arguing in public rarely helps. Reply calmly and move on.
Frequently asked questions
Can I offer a discount for a Google review?
No. Google’s policy bans incentives such as payment, discounts and free goods or services in exchange for a review, and says incentivised reviews will be removed from Maps.
Can my staff ask guests for reviews?
Yes, as long as they ask every table, do not pressure guests on the premises, do not ask for a rating or specific content, and are not given review targets or asked to collect reviews that name them.
Is a QR code for Google reviews allowed?
Yes. Google’s own tips page suggests sharing a Google link or QR code that opens your review form, as long as you are not filtering who receives it or offering anything in return.
How many Google reviews does a restaurant need?
Google publishes no target number. It says more reviews and positive ratings can help local ranking, but relevance and distance matter too. Aim for a steady flow of recent, genuine reviews rather than a one-off spike.
Can I ask a guest to change a bad review?
You can fix the problem and invite them back, but you must not offer anything in exchange for revising or removing the review. Google treats that as an incentive.
