Facebook rolls out deeper Custom Audience mobile, website targeting capabilities

In October, Facebook started testing an addition to Custom Audiences that would allow marketers to target people who had used a certain mobile app or visited a website. The company announced Tuesday that it is rolling out this capability for all.

Facebook explained this technology in a Facebook for Business blog:

For instance, a travel website with the remarketing pixel could use Custom Audiences to reach a group of people — say, people that searched for flights but never made a reservation — with a targeted message in News Feed: Come back for 10% off your next flight reservation.
