Explore the “Reach” campaign objective.

Nestled in the “Awareness” campaign category is the option to optimize an ad campaign for reach. The campaign isn’t explicitly conversion-driven, but when ad units are less expensive, it’s a good time to widen your net and bring more people in at the top of the funnel.

If you use a video as your creative, a Reach campaign actually can be conversion-driven, because you’ll grow your audience of video viewers (users who watch a video for three seconds or more) and be able to run retargeting campaigns just to those who are interested.
