Choose a winner

When to stop testing and what happens when you make a version default.

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
