In March of this year, Facebook made some changes to the way in which ad campaigns are managed; essentially providing for better campaign management via increased granularity. This allowed for significantly better A/B testing; one example being the ability to split mobile ads into a unique ad set separate from regular newsfeed ads, which proved to be exceptionally helpful. Eight months later, they’re at it again with a new update.
If you’re using Facebook ads, then you’re going to need to familiarize yourself with the new structure of campaigns coming out later this year. I wrote about it on the HostGator blog. Check it out here http://buff.ly/XFBiIS
Do you think this will be a good or bad change?
