Google review QR codes: how to make one and where to use it

By Saad D. · 2026-06-23 · 10 min read

A QR code that opens your Google review page is one of the most useful physical tools a local service business can carry. It costs nothing to make and turns a printed invoice or business card into something a customer can act on immediately - without typing a URL, searching for your business, or remembering to do it later.

This guide covers how to create one in about five minutes, where to put it, and how to use it as part of a system that actually produces consistent reviews.

What a Google review QR code is and why it works

A QR code is just a machine-readable image that encodes a URL. When a customer scans it with their phone camera, it opens a page directly - in this case, your Google review compose window, where they can leave you a star rating and write a few words.

The reason this works better than just telling someone to "go leave a review on Google" is friction. The more steps between a satisfied customer and the submit button, the fewer people will follow through. A QR code reduces it to one action - point the camera, tap the notification - and the review form is right there.

It is especially useful in situations where a customer has something physical in their hands: an invoice, a receipt, a business card, or a leave-behind magnet. Those touchpoints tend to appear at exactly the right moment - right after the job is done and the customer is happy - which is when asking is most effective.

How to create your Google review QR code for free

Step 1: Get your Google review link

You need the direct link to your review compose form before you can make a QR code.

1. Go to business.google.com and sign in to your Google Business Profile.
2. Click on "Customers" then "Reviews."
3. Look for the button that says "Get more reviews" or "Share review form."
4. Copy the link Google provides.

Test it: paste the link into a private browsing window and confirm it opens directly to the review compose screen (where you pick stars and write the review), not to your general profile page. If it lands on the profile home, go back and find the share link through the dashboard path above.

Save this link in your notes app. You will use it for your QR code and also for text and email requests.

Step 2: Generate the QR code

Several free tools make this straightforward:

• qr-code-generator.com - paste your link, click Generate, download the PNG or SVG
• Tradeloper's free Google review QR code generator - builds one straight from your review link, ready to print
• Adobe Express - free account, more design options, easy to add your logo
• canva.com - includes QR code generation if you use Canva for other materials
• goqr.me - no account needed, fast, exports multiple formats

For printing on invoices or paper materials, download the code as a vector (SVG) or at minimum a high-resolution PNG (at least 1000x1000 pixels). A small or low-resolution QR code will not scan reliably, especially when printed small on an invoice.

After generating it, test it with your own phone. If it scans cleanly and opens your review form, you are done.

Step 3: Add a brief instruction line

A QR code sitting alone on a piece of paper with no label gets ignored. Add one short line above or below it:

Scan to leave us a Google review - it takes 60 seconds and means a lot.

That is all it needs. The instruction sets the expectation and removes any uncertainty about what happens when they scan it.

Where to put your Google review QR code

On your invoices and receipts

This is the highest-impact placement for most trades businesses. The customer has just paid, the work is done, and they are holding a document they are going to look at. Put the QR code at the bottom of every invoice with the instruction line above it.

For cleaning services, pressure washing, and other businesses where invoices go out consistently, this is the easiest possible integration - add it to your invoice template once and it is on every job from that point forward.

On leave-behind cards

A small printed card (business-card size or slightly larger) that you leave with every customer after the job. One side: your name, business, and phone number. Other side: the QR code with "Thanks for your business - scan to leave us a Google review."

Leave-behind cards work well for pool service, pest control, lawn care, and other businesses where customers are not always home when you finish the work. Leave the card at the door or on the counter with a note. The customer finds it, the job is fresh, and they have something to do.

On your work van or truck

A magnetic sign or vinyl decal on your vehicle with the QR code and "Happy with our work? Scan to review us on Google." This works in neighborhoods where you are working - people see your truck, see you working, and scan out of curiosity. It also catches the attention of neighbors who might be potential customers.

For this to work, the code needs to be large enough to scan comfortably from a few feet away. Test the scan distance before committing to a printed sign.

On business cards

The back of your business card is usually blank. Put the QR code there with a short phrase. Anyone who has your card and looks at it is a warm contact - they already know who you are.

On a countertop display (for storefronts)

If you have a physical location - an auto repair shop, a grooming salon, a retail storefront - a small printed card or acrylic stand on the counter or checkout area catches customers at the moment they are finishing up and still in a positive state of mind. Dog grooming, auto repair, and garage door businesses with walk-in locations all have this opportunity.

In follow-up emails

Include the QR code as an image in your follow-up email, alongside the clickable text link. Desktop readers will click the link. Mobile readers might prefer to scan the image. Offering both removes another small friction point.

Best practices for using your QR code

Pair it with a verbal mention. A QR code alone is passive. A QR code plus "I'll leave you a card - if you have a minute to scan it and drop us a Google review, it genuinely helps us out" is an active ask. The verbal mention dramatically increases the chances the customer actually does it.

Still send the text or email follow-up. The QR code is a touchpoint, not a complete system. Some customers will scan at the door. Most will mean to and forget. The text or email request sent within 24 hours is still your highest-conversion channel. See review request templates for wording that works.

Update the code if your review link changes. If you ever need to change your Google Business Profile, re-verify your listing, or migrate accounts, your review link may change. Old QR codes pointing to broken links silently stop working. Test yours occasionally to make sure it still opens the review form.

Do not incentivize reviews. A QR code that says "Scan to leave a review and get 10% off your next service" violates Google's policies and FTC guidelines on endorsements. The ask should be a straightforward request, not a conditional offer. This applies to every method of asking - text, email, QR code, or in person.

Ask every customer, not just the ones you think will leave five stars. This is a compliance requirement under Google's terms of service - review gating (selectively asking only happy customers) is prohibited. Ask everyone, every time, and let the quality of your work determine your average.

Combining QR codes with text and email for best results

A QR code on a leave-behind card is your passive ask. The text message you send that evening is your active ask. Together, they cover two separate moments: the immediate window when the customer is still on site or just said goodbye, and the later moment when they are relaxed at home and have a minute to tap through.

For businesses without a website, the QR code and a direct text link are your entire toolkit - and that is enough to build a steady review flow for a GBP-only business.

FAQ

Will customers without a Google account be able to leave a review after scanning my QR code? Leaving a Google review requires the customer to be signed into a Google account, but the bar is lower than most trades expect - anyone with a Gmail address or an Android phone already has one, which covers the large majority of customers. When they scan and aren't signed in, Google prompts them to log in, then drops them straight back at the review form. The handful who genuinely have no account can't post, which is one more reason to also send a text or email follow-up so you're not relying on a single channel.

Should I print my star rating or review count next to the QR code? It's fine to display your real, current rating, but skip anything that nudges customers toward only-positive feedback - phrasing like "leave us 5 stars" crosses into review gating and incentivizing, both of which violate Google's policies. A neutral instruction line such as "Scan to share your honest feedback on Google" is the safe and effective choice. Remember a printed star rating goes stale as your average shifts, so a simple "Scan to review us on Google" usually ages better.

How do I tell whether my QR code is actually getting scanned? A plain QR code pointing straight at your Google review link gives you no scan data, so you're working blind. You can route the code through a short link or QR tool that reports scan counts, then compare that against the new reviews landing on your profile over the same period - if reviews lag well behind scans, the friction is at the review form, not the code. The more reliable read is simply tracking your monthly review total; consistent growth means the system is working, regardless of which touchpoint earned each one.

Where should a brand-new business with zero reviews start with a QR code? Start by getting the fundamentals in place: a verified profile and the direct review link, then put the QR code on whatever touchpoint reaches customers first - usually the invoice or a leave-behind card. Pair every code with a verbal ask at the end of the job, since early on your personal request matters far more than any printed prompt. The first ten reviews are the hardest, so ask every single customer, every time; for more ways to build that initial momentum, see how to get more Google reviews.

Do QR codes expire? The QR code itself does not expire - it is just an image encoding a URL. What can break is the URL it points to. As long as your Google review link stays the same, the QR code will keep working indefinitely. Test it every few months.

Can I use any QR code generator? Yes. For print use, export SVG or a high-resolution PNG. Avoid using screenshot-sized images (300x300 pixels), which may not scan reliably at small print sizes. Most free generators offer a high-resolution download option.

Is a QR code better than just texting the link? They serve different contexts. A text link is better for reaching a specific customer you already have contact info for - it is direct and personal. A QR code is better for physical touchpoints where you cannot send a personal message: leave-behind cards, invoices, your van, a counter display. Use both and they cover different parts of the customer journey.

The QR code gets the ask in front of customers. Start free with Tradeloper and the automated text and email follow-up handles the rest - so no satisfied customer slips through without being asked.
