# Dynamic allocation ## 📖 Definition Dynamic allocation (also called Multi-Arm bandit) is a method used to divert new traffic to the best performing variation depending on the results of each variation. It is based on the Thomson algorithm. ⚙️ Configuration\\ If one variation is performing better than the others, that is to say, if one variation has more unique conversions on the KPI you configured, new traffic will progressively be sent to that variation. Dynamic allocation is only available for A/B Tests.\ Dynamic allocation only works for new users (for an application)/visitors (for a website). If a user is assigned to a variation and returns to the website, they will still see the same variation, even if this variation is under-performing. The allocation of a recurring visitor doesn’t change over time.\ Dynamic allocation only takes into account unique conversions ## 💡 Use case The Dynamic Allocation algorithm is particularly suited to websites/applications with a lot of traffic. As soon as your A/B Test has at least one conversion **for each variation** on the selected KPI, the algorithm starts running and your users will progressively be redirected to the best performing variation. **Need additional information?** Submit your request at Always happy to help! --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
