The verdict in three sentences
The moment your customer is most satisfied — the bill, the complimentary coffee — is also the one when you never ask for a review. A QR code on the table captures that satisfaction at its peak and turns it into Google stars, the #1 signal for local Maps ranking. Done right, it takes a venue from under 1 review/week to 10-30 reviews/month and from 4.1 to 4.6 stars in a quarter.
Verbal ask, flyer or QR code: what works
Asking "leave us a review" rarely works: the customer nods and forgets on the street. The flyer ends up in a pocket. The table QR code removes all friction — one scan, two taps, it's posted.
| Method | Estimated conversion rate | Friction | Negative filtering |
|---|---|---|---|
| Verbal ask | 1-3 % | Low but forgotten | No |
| Flyer / business card | 2-5 % | Medium (to keep) | No |
| Table QR code | 10-20 % | Very low (on site) | Yes (filter page) |
| QR + NFC plate | 12-25 % | Near zero (tap) | Yes |
The key is the intermediate page: the customer rates first. 4-5 stars → sent straight to Google Business Profile. 1-3 stars → routed to a private form to fix the issue without landing in public. You protect your rating while gathering real feedback.
Impact on local SEO and cost
Reviews are one of the strongest ranking signals on Google Maps. More recent reviews, more owner replies and a high rating = more visibility in the local pack, hence more clicks and calls.
| Indicator (2026 ballpark) | Before | After 90 days |
|---|---|---|
| Google reviews / month | < 4 | 10-30 |
| Average rating | 4.0-4.2 | 4.4-4.7 |
| Maps listing clicks | Base | +25-35 % |
| Calls from listing | Base | +20-30 % |
| QR + page setup cost | — | 50,000-200,000 FCFA |
| Monthly tracking cost | — | 0-25,000 FCFA |
Setup cost (custom QR, filter page, table plates) fits within 50,000 to 200,000 FCFA one-time, with no mandatory subscription. The return comes from the call and cover volume generated by a better Maps position.

Mini case study
Ibrahim runs a restaurant in Dakar, 45 covers/day, Google rating 4.1 with 38 reviews. He installs QR codes on 12 tables. At 15 % scan-conversion on ~1,350 covers/month, he collects about 40 qualified reviews/month, the vast majority 4-5 stars thanks to the filter. In 90 days his rating rises to 4.6 and his listing climbs the local pack: +30 % Maps clicks. If that generates just 4 extra covers/day at 6,000 FCFA, that's 4 × 6,000 × 30 = 720,000 FCFA/month in additional revenue, for a setup cost paid back in days.
FAQ
Is filtering negative reviews allowed by Google? You delete no review: you simply offer unhappy customers a private channel first to fix the issue. The customer remains free to post. It's good experience-management practice, not listing manipulation.
How many reviews to climb on Maps? There's no magic threshold, but regularity matters as much as volume: 10-30 recent reviews per month and a rating above 4.5 weigh heavily. Replying to each review further strengthens the signal.
Do customers need an app? No. The QR opens a simple mobile web page, no download. Two taps land them on the Google review form.
Printed QR or NFC plate? A printed QR costs almost nothing and works everywhere. The NFC plate (one tap, no framing) converts slightly better but costs more per unit. Many venues combine both on the same plate.
Does it work for a salon or clinic too? Yes, any business with an identifiable satisfaction moment: hairdressing, spa, dentist, garage. The principle is identical — capture the review at the experience peak, on site.
