The QR code marketing guide for small businesses
Where to place QR codes, how to design them, and the metrics that actually matter.

QR codes are no longer a gimmick. After 2020, they became part of every restaurant menu, every product label, every event lanyard. Used well, they’re a free distribution channel between physical and digital. Used poorly, they’re a sticker no one scans.
Where QR codes actually work
The best QR codes live where people have time and a reason to scan:
- On packaging — pointing to instructions, warranty, or tutorial videos.
- In waiting areas — menus, loyalty signups, Wi-Fi credentials.
- On printed receipts — review prompts, reorder pages, WhatsApp chat.
- On business cards — direct to your LinkedIn or contact form.
- In storefront windows — for after-hours discovery.
Bad places for QR codes: billboards drivers can’t safely scan, TV ads on screens not pointed at, ten-second Instagram stories.
Three design rules
- Contrast wins. Dark code on light background is most reliable. Avoid colored backgrounds unless you’ve tested in low light.
- Bigger than you think. As a rule, 2.5 cm × 2.5 cm minimum, larger for distance scans.
- Always label it. A short “Scan to view our menu” outperforms a naked QR by orders of magnitude.
Metrics that matter
Static QR codes (the kind we generate) can’t track scans on their own. If you need analytics, route the QR to a tracked landing URL with UTM parameters:

The takeaway
A QR code is just a clickable link in the physical world. Treat it that way: place it where people have intent, give them a reason to scan, and measure what happens after.
