What does Google allow when you ask for reviews?
Asking is fine. Asking only some people is not. Google's policy does not allow a business to selectively ask only happy customers for reviews, or to offer incentives for them.
That rules out the popular trick of sending a "how did we do?" survey first and passing only the happy answers on to Google. It also rules out a discount, a gift card or a raffle entry in exchange for a review, even if you do not care which way the review goes.
The safe version is boring. Send the same request, with the same link, to every customer you served.
How do you get your Google review link?
Google lets you create a link or QR code to request reviews from your Business Profile. The steps on Google's help page are short.
- Go to your Business Profile.
- Select Read reviews, then Get more reviews.
- Copy the link, or download the QR code to print.
Google's page says you can put the link on receipts, in thank-you emails and at the end of a chat, and print the QR code for your counter. A link on a receipt is easy to forget, so pick one place and make it automatic.
Who should you ask, and when?
Ask everyone you served. Ask soon after the job, while the customer still remembers it. A plumber who asks the same afternoon gets a more specific review than one who asks three weeks later, and specific reviews are the ones that persuade the next customer.
Ask the people you are a little nervous about, too. That is the part that feels wrong and is the whole point of the policy.
What should the request say?
Short, friendly, one link. Here is a made-up example for a plumbing company. Change it to sound like you.
"Hi {name}, thanks for choosing {business}. If you have a minute, we would value an honest review on Google. Here is the link."
Notice what is missing. There is no rating question, no offer, and no hint about what you hope the review says. Asking for an "honest" review is fine. Asking for a "5-star" review is not.
How many reminders are too many?
One. Some customers meant to do it and forgot, and a single polite nudge reaches them. A second and third start to feel like pressure, and pressure produces the reviews you do not want.
In OpenGMB the reminder goes out 1 to 14 days after the first email, and only to people who have not clicked the link.
What mistakes cost you reviews or get you in trouble?
- Screening first. A survey that sends unhappy customers somewhere else is review gating.
- Paying for reviews. Any incentive tied to posting a review is out.
- Buying a list. Email only people who have actually done business with you.
- Asking and then not replying. When the reviews arrive, answer them. The guide on how to reply to Google reviews covers it.
How do you do this with OpenGMB?
OpenGMB sends the request as an email campaign for one location. Every recipient gets the same message and the same link to Google's review form. There is no rating question and no routing of unhappy customers. The feature is described on the Google review request links and QR codes page.
- Open Review requests and choose the location. If it has no review link yet, add it first.
- Create a campaign. Write a short subject and message, or keep the plain default.
- Add recipients, and confirm you have permission to email them.
- Start the campaign. OpenGMB refuses wording that asks for a rating or a survey.
Nothing is sent until a campaign is started. If you use Claude or another MCP client, connect the server at https://opengmb.synectus.com/mcp (the MCP setup docs have the steps) and use the prompt below. It looks up the location's review link and creates a draft campaign with reviewRequests_create. It does not start it.
Prompt for Claude or any MCP client
Use the opengmb MCP server. Call locations_list and find the location named
[LOCATION NAME]. Call reviewLinks_get for it. If it has no review link, stop
and tell me.
Otherwise create a draft email campaign with reviewRequests_create. Write a
short subject and a message of two to four sentences that thanks the customer
and asks for an honest review. Use {name} and {business}. Do not mention
ratings, stars, a survey, a discount or any other offer.
Do not start the campaign and do not add recipients. Tell me the campaign
name so I can review it.You add the recipients and start the campaign yourself, so you decide who gets an email. A token only does what its owner's rights allow, and a read-only token cannot create a campaign at all.
Questions about asking for Google reviews
Can I ask customers for Google reviews?
Yes. Ask everyone you served, with the same link, and offer nothing in return. Google's policy does not allow a business to selectively ask only happy customers for reviews, or to offer incentives for them.
Where do I find my Google review link?
Google lets you create a link or QR code to request reviews from your Business Profile. In your Business Profile, select Read reviews, then Get more reviews, and copy the link or download the QR code.
Can I give a discount for a review?
No. Google does not allow incentives in exchange for a review, including discounts, gifts and payment.
Can I ask only my happy customers?
No. Asking only the customers you expect to be happy is selective solicitation, and Google's policy does not allow it. Send the same request to everyone.
How many reminders should I send?
One is enough. OpenGMB sends at most one reminder, to people who have not clicked the link.
Can Claude draft my review request?
Yes. Connect the OpenGMB MCP server and ask Claude to create a draft campaign. It is not sent until someone starts it.
