**How to Run Exclusive Experiments**

Learn how to create exclusivity groups and make experiments mutually exclusive.

[Exclusivity groups](/docs/capabilities/experiments/exclusive-experiments.md) ensure that experiments don't overlap, so no user is in multiple experiments at the same time.

## Create an Exclusivity Group

If you don't already have an exclusivity group, create one first:

**1. Go to Surfaces on the left sidebar**

**2. Select the surface**

**3. Select Settings**

**4. Select Add exclusivity group**

**5. Configure the exclusivity group**

Give it a name and description. Choose whether it should be marked as suggested, which means it will be automatically pre-selected for experiments on the surface.

## Make an Experiment Exclusive

**1. Go to the experiment**

Go to Confidence and find the A/B test or rollout you want to make mutually exclusive with other experiments.

**2. Select the surface**

Select the surface on which the exclusivity group lives.

**3. Select the exclusivity group**

Select the exclusivity group you want to use.

**4. Click Save**

The experiment is now mutually exclusive with other experiments that share the same exclusivity group.
