The A/B Test function lets you distribute users between two flow paths (A and B) using a defined proportion, helping you compare the performance of different pages, offers, or sequences. ## How it works You set a percentage for path A. Path B automatically receives the remainder up to 100%. When the user reaches this function, XQuiz chooses a path based on that distribution and continues the flow accordingly. ## How to set up 1. Add the A/B Test function to the Flow. 2. Set the percentage for path A in “Percentage A (0–100)”. Path B is calculated automatically. 3. Connect “A” to the first step of path A and “B” to the first step of path B. 4. Publish and monitor the results in your funnel or external tool. ## Best practices * **Define a hypothesis**: what outcome are you aiming to improve (e.g., conversion, clicks, retention)? * **Keep changes isolated**: modify just one element at a time for clear results. * **Time and sample size**: run the test long enough and with adequate volume. * **Avoid the same destination**: A and B should not point to the same node; the Builder prevents this link.
