My QR Code Marketing Experiment (What Got Scanned vs Ignored)

Last month I ran a dumb little experiment. Nothing scientific enough for a journal, but very practical for anyone who uses QR codes in the real world.

I created 12 QR codes pointing to different content — a blog post, a discount page, a newsletter signup, a product page, a PDF download, and a few other things. I placed them in different contexts: printed flyers, digital screens, email signatures, social media posts, business cards, and even a sticker on a street pole (sorry, city maintenance people).

Then I tracked what happened for two weeks.

The Winners

1. The discount page QR code on a checkout screen. This one killed it. 142 scans in two weeks. Context is everything — someone who's already buying is highly motivated to scan a code that saves them money. I placed a small sign next to the card reader that said "Scan for 10% off your next order." Almost every customer who saw it scanned it.

2. The newsletter signup on a printed flyer at a coffee shop. 68 scans. The flyer was on a community bulletin board — you know, the corkboard with a million other flyers, takeout menus, and lost cat posters. I made the QR code large and surrounded it with a bright border. People scanning it were already reading the flyer, so the call to action was immediate.

3. The blog post link in a social media bio. 47 scans. Not huge, but consistent. The interesting finding: scans spiked in the evenings. People see a QR code in a bio, screenshot it, and scan it later when they're on a different device.

The Failures

1. The sticker on a street pole. Zero scans. I'm not surprised. I walked past it several times and almost forgot it was there. QR codes in the wild need a compelling reason to exist, and "scan this to see a blog post" isn't it.

2. The product page QR code on a business card. 3 scans. People don't scan business cards. They pocket them and forget about them. If you're putting a QR code on a business card, at least make it point to something immediate — a contact save, not a product page.

3. The PDF download link in an email signature. 1 scan. Probably me testing it. Email signatures are invisible. Nobody looks at them.

What I Learned

After running this, I have three rules for QR codes:

1. Context is everything. A QR code without context is just a weird square. Tell people what they'll get before they scan. "Scan for recipe" beats a naked QR code every time.
2. Make it big. I printed one code at 2cm and one at 5cm on the same flyer. The big one got ten times more scans. Size matters.
3. Test the damn thing. You would not believe how many QR codes I've scanned that point to a 404 page or a broken link. Test your code before you print a thousand flyers.

If you're running your own experiment, I'd start with QR Code Generator — it's what I used. It lets you generate dynamic codes that you can edit after printing. That part saved me when I realized I'd sent one code to the wrong URL. No need to reprint. Just updated the destination and moved on.
