You can connect your custom shopper segments to your Facebook advertising account, and target the same or similar shoppers (or both at the same time) via a newly created campaign. 

Here is how the process works.
​
While in "Shopper Analytics" click on the “Action” box and select “Custom Facebook Audience” from the drop-down menu. 

Select the segment you wish to target via your Facebook ad campaign. Simply click on the box next to “Select a segment” and choose the segment you want to target via the drop-down menu. Follow the rest of the instructions.
