Experiment Summary
Ended On: 06/11/2021
Focus on the Family created some trailers for their video series. This offered the opportunity for a great test to see whether a more engaging form of creative on a Facebook ad will increase engagement. We tested the trailers against their typical screenshot of the video series against the trailer as the medium for the ads. This was a marketplace test, not a strict A/B test on Facebook. We ran both creatives in the Facebook campaign to which one the market prefers and engages with more readily.
Research Question
