If you wanted to raise awareness about your brand, look no further than Facebook video ads.
These types of ads work so well because they play automatically in the news feed. If your video is interesting enough, viewers will stick around to watch. However, the chance that they will actually click the ad is much lower than a regular ad.
To address this, Facebook has recently rolled out an elegant solution. You can now create audiences for OTHER ADS built out of people who have watched your videos in the past.
