 ### Step 2a: Connecting to a destination
 
 [Destinations](/docs/connections/destinations/) are the business tools or apps that Segment forwards your data to. Adding a destination allows you to act on your data and learn more about your customers in real time. To fully take advantage of Linked Audiences, you must connect and configure at least one destination.
