A/B testing inside one short link — no code

The idea

You publish one link (e.g. cd4cd.com/spring-sale). Every visitor is routed to one of the destinations by a chosen ratio. CD4CD reports which destination converts better.

Setup in 3 steps

1. Open /dashboard/links, click "Create link".
2. In "Advanced options", toggle "A/B Testing".
3. Add destinations + ratio (50/50, 70/30 …).

Reading results

After 24–48 hours, check /dashboard/analytics:

• Total clicks per destination.
• Conversion rate (if you set the tracking pixel).
• Device + country breakdown — sometimes Variant B wins on iOS and loses on Android.

When to stop?

The 100 rule: never call a winner until each variant has 100+ conversions. Below that, it's noise.
