Every review-collection method, from a tap card to a WhatsApp message to a printed QR code, depends on one thing: a Google review link that opens the review box in a single tap. Get that link wrong, and customers land on your listing, not the form, and most of them give up. This guide shows how to find your Google review link, the two kinds that work, how to check yours with a free link checker, and how to use it on an NFC review card, QR code, WhatsApp message and email, with the rules Google expects you to follow. IT-Support-SA supplies and installs Google review NFC cards from Pietermaritzburg for businesses across South Africa.
The Short Answer
Your Google review link is either the short link from your Google Business Profile (it looks like g.page/r/…/review) or a write-review link built from your Place ID (search.google.com/local/writereview?placeid=…). Both open the review box straight away. A Maps share link does not: it opens your listing. Get the link, test it on a phone signed in to a different Google account, then use the same link on your NFC card, QR code, WhatsApp messages and invoices, and ask every customer, not only the happy ones.
What a Review Link Does (and Why It Matters)
A review link skips the steps between “yes, I’ll leave a review” and the review form. Without it, the customer has to search for your business, open the listing, find the reviews and tap the right button. Each step loses people. With it, one tap opens the box with the stars ready. That is the whole difference, and it is why every method in our guide to how to get more Google reviews depends on having the right link.
It also explains why a tap card beats a printed web address. A card can carry the link, so the customer never types or searches anything, which we cover in why every South African business needs a Google review NFC card.
The Two Links That Work
1. The short link from your Google Business Profile
This is the easiest. Sign in to the Google account that manages your profile, search for your business name on Google, and choose Ask for reviews (sometimes labelled Get more reviews). Google shows a short link, normally starting with g.page/r/ and ending in /review, along with a button to copy or share it. It is short, so it makes a small, clean QR code.
2. A write-review link built from your Place ID
Every business listing has a Place ID, a code that usually starts with ChIJ. Google’s free Place ID Finder shows it when you search for your business. Put it on the end of the standard address and you have a working link:
https://search.google.com/local/writereview?placeid=YOUR_PLACE_ID
This is a good backup when you cannot reach the short link, for example when an agency or a former employee manages the profile. Both links fit comfortably on an NFC tag, which has room for roughly 137 bytes of data on the smallest common chip.
The link that does not work: a Maps share link
If you search for your business in Google Maps and press Share, you get a link such as maps.app.goo.gl/…. It opens your listing, not the review form. Customers then have to find the review button themselves, and most will not. If your review card is underperforming, check this first.
Check and Build Your Link
Paste your Place ID or the link you have. The tool tells you which kind it is, fixes what it can and builds the message to send. It also shows how much space the link takes on an NFC tag.
A few things to know about the result. If you paste a profile short link without the ending /review, the tool adds it. If you paste a Maps share link, it tells you why that will not work. The message it builds is deliberately neutral: it asks for an honest review and does not steer anyone towards a good rating, which is what Google’s policies expect. Always press Test it and open the link on a phone before printing or sending anything.
Where to Use Your Review Link
On an NFC review card
A tap card carries the link, so the customer taps their phone on the card and the review box opens, with no app and nothing to type. We recommend that the tag does not hold the Google link directly. Point it at an address on your own domain that redirects to the link. If Google ever changes the format, or you move to a different profile, you change the redirect once and every card keeps working. It is also what lets the tag be password-protected without being locked for good. The reasons are in our guide to whether NFC tags are safe, and our buyer’s guide to choosing an NFC card supplier lists what to ask before you buy.
On a QR code
A QR code is a sensible backup beside a tap card, because some customers reach for the camera first. Make it from the same link with any QR generator, scan it with two different phones before it is printed, and print it large enough to scan from a normal distance. Avoid generators whose codes stop working when a free trial ends: a printed code that quietly dies is the same problem as a tag that points at a lapsed address.
On WhatsApp
For trades, home services and any business that already talks to customers on WhatsApp, a personal message soon after the job works well. Put the link on its own line so it is easy to tap. The builder above makes the message and a Share on WhatsApp button. Two rules keep it on the right side of the law: send it to customers you have just served, one at a time, and avoid bulk messages to a list, because direct marketing by electronic message needs consent under Section 69 of POPIA. If you want to automate it, see our guide to connecting AI to WhatsApp, email and your business systems.
On invoices, receipts and email signatures
Add the link, or a short address on your own domain that redirects to it, to the footer of every invoice, quote and email. It costs nothing, and it reaches the customer at the moment they are reading about the work you did.
On your website
A “Review us on Google” button that uses the same link works for visitors who are already on your site, and it makes sure the website, the card and the WhatsApp message all send people to the same place.
Ask Every Customer, the Same Way
How you ask matters as much as what you send. Google’s policies are clear on three points:
- Do not offer rewards for reviews. No discount, no entry into a draw, no free item in exchange for a review.
- Do not ask only for positive reviews. Asking only the customers you think are happy, or sending unhappy ones somewhere private instead, is called review gating, and it is prohibited. Ask everyone, the same way.
- Do not write reviews yourself, or have staff or family do it.
A private feedback option for customers who would rather tell you directly can sit beside the review link, as long as every customer sees both and nobody is steered away from Google. Then reply to every review, good or bad. Our guide on how to handle bad Google reviews covers how to answer the difficult ones.
Test It Before You Print
Spend five minutes on this before you commit to a batch of cards or a print run:
- Open the link on an iPhone and an Android phone. It should open the review box, not your listing.
- Test it signed in to a different Google account from the one that runs your profile. You cannot always review your own business from its own account.
- Test on mobile data as well as Wi-Fi.
- Scan the QR code with two phones, at the size it will be printed.
- Tap the NFC card on both phone types, in the place it will sit.
- Check the business name on the review screen. It should be yours, in the right location.
If Your Review Link Is Not Working
- It opens your listing, not the review box. You probably used a Maps share link. Replace it with the short link or the Place ID link.
- It shows the wrong business. The Place ID belongs to a different listing, perhaps an old duplicate. Check the name and location on the Place ID Finder.
- Customers cannot post. They have to be signed in to a Google account, and a very new account may be restricted. Offer to let them try again later.
- Reviews appear to be missing. Google filters some reviews automatically, so a new review may take a while to show or may not show at all. Check that it is not a link problem before you worry.
- The QR code or tag worked and then stopped. The address behind it may have changed or lapsed, which is why an address you own matters.
How IT-Support-SA Sets It Up
When we install review cards, we confirm the correct review link for your Google Business Profile, build it from your Place ID if needed, point the tag at an address you control, password-protect it, and test it on an iPhone and an Android in the position the card will actually sit. We can also set up a QR code to match and a WhatsApp message saved on your phone, so the same link is used everywhere. Installation is on site, with travel outside our main service areas quoted upfront. See our Google Review NFC Cards page or send us an enquiry.
Mistakes That Waste Reviews
- Using a Maps share link and sending customers to a listing.
- Never testing the link on a phone signed in to a different account.
- Printing before testing, so a bad link is fixed on a thousand cards.
- Putting the Google link directly on a tag with no way to change it later.
- Using a QR generator that expires, so the printed code stops working.
- Asking only the happy customers, which Google prohibits.
- Offering a discount for a review, which Google also prohibits.
- Sending bulk WhatsApp messages to a list that never agreed to receive them.
Conclusion
A review link is a small thing that decides whether every other review effort works. Get the short link from your Google Business Profile, or build one from your Place ID, check it with the tool above, test it on two phones, and use the same link everywhere: on the NFC card, beside a QR code, in WhatsApp messages and in your invoices. Ask everyone, in the same way, for an honest review, and reply to all of them.
