Re: The interesting part is the matching algo
I think they work more so on matching ads with eyeballs full stop. They still think it's OK for my young kids to see 18 rated ads with the kind of videos they watch. Admittedly they're using my account (yes I know but one account on the TV only and restricted mode doesn't appear to make a difference) so Google think it's fair game, but shows ads matching content is not top priority.
