Brand Collaboration is said to be trending this season. Facebook is also going to test a new feature that will feature multiple advertises in a single unit bundling dynamic ad campaigns. As of now, the format is said to be a small test which basically involves advertisers who have agreed to participate.
The new format seems to be appealing to media buyers with retail investors. Over the years, Facebook's traditional ad units seemed to have gotten more expensive. In this new format, group product recommendations from different advertisers are clubbed into a single experience. However the pricing model is yet to be decided by Facebook.
