A Google review QR sign is one of the highest-ROI investments a local business can make. It works passively, 24 hours a day, without staff effort, converting satisfied customers into reviewers at the exact moment their experience is freshest.
This guide covers the best sign types, materials, placements, and designs for every type of local business.
What makes a great review QR sign
The best review signs share a few things:
- Clear headline, "Leave us a Google review" or "Scan to review us", no ambiguity
- The QR code large enough to scan from 12–18 inches, minimum 1.5 inches square for countertop cards, 3 inches for wall signs
- A short explanation, "Takes 60 seconds. We really appreciate it." removes hesitation
- Google's logo or star icon, makes it immediately recognizable
- Your business name or logo, so it feels intentional, not generic
Best sign types by business
Restaurants and cafés
Best placement: Table tent, check presenter, front door
A table tent sits where the customer's eyes already are during the meal. A check presenter gets seen at the highest-intent moment, when the bill arrives. Both work better than a wall sign because they're close and visible.
Print on thick cardstock (at least 300gsm) and laminate for durability with food and liquid exposure. Replace them when they look worn.
Salons, barbershops, and spas
Best placement: Mirror card, checkout counter, styling station
A mirror card is visible during the service finish and may be easier to notice than a distant sign. Test it against a checkout placement and compare recorded scans for your own salon.
Use a vertical card (business card size or slightly larger) that can stand or clip to the mirror base. Acrylic stands work well here.
Auto shops
Best placement: Invoice footer, key return counter, waiting area
The invoice footer is the single best placement for auto shops. The customer is already reading the bill, a QR code printed at the bottom requires zero extra attention. Add a one-line CTA: "How'd we do? Scan to leave a Google review."
The key return counter gets the customer at the highest-satisfaction moment: when they're getting their car back. A small sign or a card inserted with the keys both work.
Contractors and field service businesses
Best placement: Job-completion card, invoice
A business card or postcard-sized job-completion card handed over at the end of work is perfect. It acknowledges the job is done, thanks the customer, and gives them a QR code to scan on the spot.
The key is handing it over in person, not mailing it later. "Here's your invoice and a review card, if you're happy with the work, I'd really appreciate a quick Google review while I finish packing up" is a natural, uncontrived ask.
Retail stores
Best placement: POS counter, shopping bag insert, fitting room
The POS counter sign works well during card payment, customers are already looking down at the counter. A bag insert reaches customers after they leave (lower conversion but better than nothing). Fitting room cards target customers at a quiet moment during the shopping process.

What NOT to do with review signs
- Don't make the QR code too small, anything under 1.5 inches square at the final print size may fail to scan
- Don't use URL shorteners that track without disclosure, just link directly to Google
- Don't put the sign where it looks like an afterthought, a sign taped to a wall at eye level in an empty hallway gets no scans
- Don't set it up once and forget it, test the QR code quarterly to make sure it still works
- Measure more than sign placement, compare scans, opt-ins, deliveries, and clicks to learn what works for your customers
The complete sign setup that works
The businesses getting the most Google reviews from their physical signs typically combine:
- A well-placed QR sign at the highest-intent moment
- A verbal mention from staff ("Feel free to scan that sign before you go")
- A follow-up text the same day with the review link
Signs are a passive layer and SMS is an active follow-up layer. Measure scans, opt-ins, deliveries, and clicks to evaluate how the combination performs for your customers.
