# Choose a winner ### When to choose a winner Choose a winner when: * one version is clearly trending better * you’ve collected “enough” traffic to feel confident * you’re ready to stop testing and keep the best version live You don’t need perfect statistical certainty. Directional decisions are usually enough. ### How to choose a winner (and what happens) On the Results page, select **Make Default** on the version you want to keep. When you do: * the test stops * 100% of traffic goes to the winner * your swtchd link stays the same forever --- # 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.
