A/B Testing for QR Codes: Let Data Pick the Winner.

A/B testing is standard practice for email campaigns and digital ads — yet most businesses never apply it to their physical QR campaigns. SMLLR changes this. Set up an A/B test on any QR code: 50% of scans go to Version A (your current landing page) and 50% go to Version B (your new variant). After enough scans, your dashboard clearly shows which version converts better. Then you point 100% of traffic to the winner — with one click.

The best A/B tests for QR campaigns are those that test meaningfully different approaches. Test two different landing pages with different headlines and CTAs to see which message resonates with your offline audience. Test a WhatsApp chat destination versus a form submission destination to understand which conversion path your customers prefer. Test a video landing page versus a text-only page to measure if rich media increases engagement. Every test adds to your understanding of what drives QR-triggered conversions in your market.

When testing something new, you might not want to send 50% of your valuable traffic to an unproven variant. SMLLR's Weighted A/B Testing (available on select plans) lets you set custom traffic splits — e.g., 90% to your proven control and 10% to the new experimental variant. Once the variant shows promising results, gradually increase its traffic share until you are confident enough to declare it the winner.
