1. Keep It Under 60 Seconds

Why: Attention spans are short. After 60 seconds, people tune out or stop listening.

Bad example (too long): 2-minute rambling message with unnecessary details

Good example: 45-second focused message with one clear point

Pro tip: Aim for 30-45 seconds. If you need more time, you're trying to say too much.

2. Start Strong (First 3 Seconds Matter)

Why: People decide in 3 seconds whether to keep listening.

Bad opening: "Um, hi, thanks for scanning this, uh..." Good opening: "Flash sale! 50% off everything for the next 2 hours!"

Pro tip: Lead with the most interesting part. Hook them immediately.

3. Write How You Speak, Not How You Write

Why: Audio sounds awkward when you use formal writing language.

Bad (written style): "Our establishment is pleased to offer complimentary beverages to valued customers who..." Good (spoken style): "Hey! Buy any entree and get a free drink. Just mention this QR code!"

Pro tip: Read your script out loud. If it sounds unnatural, rewrite it.

4. One Clear Call-to-Action

Why: Multiple CTAs confuse people. They do nothing instead of picking one.

Bad (too many CTAs): "Visit our website, follow us on Instagram, sign up for our newsletter, call us, text us, or stop by our store..." Good (one clear CTA): "Text 'SPECIAL' to 555-0123 to claim your discount."

Pro tip: Choose the ONE action that matters most. Make it simple.

5. Test Before You Print

Why: Typos, wrong phone numbers, or unclear messages waste money when printed.

Testing checklist:

  • Scan QR code yourself
  • Listen to full audio
  • Check all numbers/URLs are correct
  • Verify QR code scans on multiple phones
  • Ask a friend to scan and give feedback

Pro tip: Print one test copy before ordering 1,000.

6. Choose the Right Voice

Why: Voice creates mood. Wrong voice = wrong impression.

Professional business: Deep male voice (credibility) Kids products: Friendly female voice (warm, approachable) Luxury items: Mature, sophisticated voice Youth marketing: Young, energetic voice Restaurants: Warm, inviting voice

Pro tip: Match the voice to your brand personality.

7. Size Matters (Make QR Code Big Enough)

Why: Tiny QR codes are hard to scan. People give up.

Minimum sizes:

  • Business card: 1 inch × 1 inch
  • Flyer: 2 inches × 2 inches
  • Poster: 3 inches × 3 inches
  • Billboard: 1 foot × 1 foot

Pro tip: Rule of thumb: Scanning distance should be 10× the QR code size.

8. Add Context Text

Why: Plain QR codes look suspicious. People don't know what will happen when they scan.

Bad: Just a QR code with no explanation Good: QR code with text: "Scan to hear today's special!"

Great context examples:

  • "Scan for instant property details"
  • "Hear from the chef"
  • "Get your discount code"
  • "Listen to my introduction"
  • "Exclusive message inside"

9. High Contrast Colors

Why: Low contrast QR codes don't scan well.

Best: Black QR code on white background Also works: Dark blue on light yellow, dark red on white Avoid: Light colors on light backgrounds, dark on dark

Pro tip: Test your QR code in different lighting conditions (bright sun, dim room).

10. Update When Relevant

Why: Old information damages credibility. Dead links frustrate people.

Update when:

  • Event date changes
  • Pricing changes
  • Phone number changes
  • Promotion ends
  • Product sold out
  • New information available

Pro tip: Set calendar reminders to review your QR codes monthly.

Bonus Best Practices

Create Urgency

"This offer expires Friday!"
"Only 10 spots left!"
"First 50 people get free shipping!"

Use Social Proof

"Over 500 customers bought this last week"
"Rated 4.9 stars by 1,200 people"
"Featured in Forbes and TechCrunch"

Make It Personal

Use "you" and "your" instead of "customers"
Example: "Your order will ship within 24 hours" vs "Orders ship within 24 hours"

Include Specific Numbers


"3-bedroom house" is better than "Spacious house"
"Delivered in 2 days" is better than "Fast delivery"

Common Mistakes to Avoid

  • ❌ Robot voice that sounds unnatural
  • ❌ Background noise in recording
  • ❌ Mumbling or speaking too fast
  • ❌ No clear next step
  • ❌ Forgetting to include contact info
  • ❌ Making it about you instead of the customer
  • ❌ Using jargon or complicated language

Testing Your QR Code

Before launching, test:

  1. Scan with 3 different phones (iPhone, Android, older model)
  2. Test in different lighting (bright, dim, outdoor, indoor)
  3. Try from different distances (close up, far away)
  4. Check audio quality on phone speaker vs headphones
  5. Verify all links/numbers work

Measuring Success

Track these metrics:

  • Scan rate: How many people scan vs see it
  • Completion rate: How many listen to full message
  • Action rate: How many complete your CTA
  • Revenue: Sales attributed to QR code
