## **Cookieless Activation**

Cookieless Activation allows you to reach audiences that are traditionally unreachable due to the lack of third-party cookies, thereby expanding your reach.

### **How to activate:**

2. In the Ad Set window, under Audience, you will see the **Cookieless** option. Click Lookalike to expand, then select one of the third-party Cookie Type inventory options: All, Cookies (default setting), or Cookieless.

- **All**: Includes cookie and cookieless inventory. See below for cookieless inventory restrictions.
