We recently posted here that for some odd reason the number of students in the UK that were part of the Facebook ad platform plummeted, and marketers weren’t sure why. But this latest post in the Reach Students blog highlights how the missing 3 million UK students from the Facebook platform in September have returned this month. Apparently, it was some sort of rule in Facebook’s ad system which was blocking out the majority of the student audience during September. Looks like advertisers will be happy with these results once again!
