Problem: The printed flyer is ready — which landing page should it point to?
You printed 10,000 flyers and have different ideas about where to direct prospects: a long product page, a short offer page with a form, or a dedicated discount landing page. Reprinting is not an option. You want to test live which variant brings more sign-ups or leads — and measure it precisely.
Why a dynamic QR code is the perfect foundation for A/B tests
With a dynamic QR code the printed code stays the same while the destination (the URL) can be changed afterward. This allows multiple landing pages to be operated behind a single QR code and served differently via a server-side split redirect. Important for companies: centralized management, the ability to evaluate scan counts server-side, and the option to control variants automatically via API.
How to run a QR A/B test with Linkentra — step by step
1. Define variants: clear hypotheses
Formulate a measurable question: “Does variant A (long product detail page) generate more leads than variant B (short form) within two weeks?” Provide the target URLs as separate landing pages. Use a consistent tracking event on the pages (e.g., form submission) so you can unambiguously attribute conversions.
2. Create variants in Linkentra
Create dynamic targets in Linkentra for each landing page. Use the media management for accompanying assets (e.g., specific images or PDFs) and give each variant a meaningful label (A, B, Discount, Form, etc.).
3. Configure split redirect
Create the dynamic QR code that controls the split redirect. Distribute visitors evenly at first (e.g., 50/50). Linkentra allows you to manage target assignments and set percentages — the server decides at scan time which landing page is delivered. Advantage: assignment is done server-side, client-side manipulation is avoided, and you get clean scan counts.
4. Use tracking & server statistics
Server-side evaluation of scans is essential. Linkentra records how many scans went to which variant. Combine these scan counters with the conversion data from your landing pages (e.g., via web analytics or webhook integration). This way you calculate reliable conversion rates per variant: scans → visits → conversions.
5. Automation via API
Put test control on autopilot: with the Linkentra API you can programmatically create variants, change percentages, and roll out assignments automatically. Practical use cases:
- Rotate by schedule: mornings 60/40, afternoons 40/60.
- Automatic ramp-up: new variant starts at 5% and grows with good performance.
- CI/CD integration: manage A/B configurations as code to make test runs reproducible.
The API also provides access to scan and performance data, so you can feed external BI tools with up-to-date values or generate automated reports.
Practical examples: three tangible scenarios
1. Event organizer: maximize sign-ups
Problem: Printed posters at multiple locations, but it’s unclear which page leads to more sign-ups. Solution: One QR code per poster design with a split redirect to “detailed info” vs. “direct sign-up.” After two weeks the server-side statistics clearly show the better variant; the winning variant is automatically set to 100% via the API.
2. Gastronomy: menu vs. daily specials
Problem: Test different menu concepts without printing new table tents. Solution: QR on table tents uses a split redirect between the standard menu and a temporary specials page. Scan counters and time on the landing page reveal whether the daily special actually generates more interest.
3. Retail product launch
Problem: Two product presentations — which communicates the unique selling point better? Solution: QR code on the shelf splits visitors between two variants. Webhooks inform your CRM in real time, and you evaluate the variant results via export (CSV/JSON).
Concrete tips for meaningful tests
- Sample size: Plan for enough scans before deciding. Small samples lead to false conclusions.
- Change only one variable: Test only one change at a time (e.g., call-to-action or form layout), otherwise the cause is unclear.
- Combine data sources: Use both Linkentra scan statistics and conversion tracking on the landing page.
- Automate reporting: Webhooks or API pulls provide up-to-date dashboards without manual effort.
- Plan a fallback: Automatically switch to a safe target page when predefined conditions are met (e.g., poor performance of a variant).
Checklist before, during and after the test
- Before the test: Formulate a hypothesis, define goals (e.g., conversion rate), create variants.
- During the test: Split redirect active, monitor scan counters, check webhooks/analytics.
- After the test: Statistically relevant analysis, route the winning variant via API, document lessons learned.
Which metrics should you keep an eye on?
- Scans per variant (server-side counter)
- Visit rate / bounce on the landing page
- Conversion rate (e.g., form completions)
- Time on page and page flows
- Cost per conversion (if campaign costs apply)
Conclusion: Test fast, measure cleanly, switch automatically
QR A/B tests with dynamic codes give you the flexibility to run live experiments on printed material. Linkentra combines dynamic targets, server-side scan statistics and API automation — so you can test variants reliably, evaluate results centrally and automatically roll out winners. For companies, agencies and event organizers this means less risk, faster learning and a clearly measurable improvement in campaign performance.
