# Can I add multiple creatives in the same Brand Lift ?

If you want to compare creatives in order to analyze which worked best for your campaign goal, you can. You’ll have to set up **one measurement per creative.**

In the **Media Plan tab**, add your first creative, then click on **+ Add channe**l at the button of the page to add another media and creative.

⚠️ Each channel must reach at least 100,000 unique exposed individuals to be eligible for measurement and please note that one creatives = one measurement.&#x20;

## I can run only one Brand Lift, what should I do ?

We advise you to select which **best represents your campaign’s objectives** or the one with the **biggest budget**.
