QR Code Best Practices for Business

1. Provide Clear Value

People won't scan without a reason. Always communicate what they'll get: "Scan for 20% off" or "Scan to view menu" is more effective than a bare QR code.

2. Mobile-Optimize Your Destination

100% of QR code scans happen on mobile devices. Ensure your landing page is mobile-friendly, loads fast, and works well on both iOS and Android.

3. Test Thoroughly

Test your QR code on multiple devices and at the actual size/distance it will be used. What works on screen may not work on a billboard from 50 feet away.

4. Size Appropriately

Use the 10:1 rule: divide the scanning distance by 10 to get minimum size. A code scanned from 10 feet away should be at least 12 inches.

5. Brand Your Codes

Customize colors to match your brand while maintaining sufficient contrast. You can even add a small logo in the center (with high error correction).

6. Consider Dynamic vs Static

For permanent materials (business cards, product packaging), decide if you need the ability to change the destination URL later. Learn about dynamic QR codes.

Measuring QR Code Success

Track these metrics to understand your QR code performance:

• Scan rate: Number of scans vs. impressions
• Unique vs. total scans: How many different people scanned
• Conversion rate: Scans that led to desired action
• Time/location: When and where scans happen
• Device breakdown: iOS vs. Android users

Use UTM parameters in your URLs (e.g., ?utm_source=flyer&utm_campaign=spring2025) to track QR code traffic in Google Analytics.

Common Mistakes to Avoid

• QR code without context: Always explain what scanning will do
• Broken links: Test codes before printing and periodically check they still work
• Non-mobile pages: Desktop-only sites frustrate mobile users
• Too small or too dense: Ensure reliable scanning
• Inaccessible placement: Codes in subway tunnels (no signal) or moving vehicles (can't scan) won't work
• No tracking: Without analytics, you can't measure ROI
