Targeting, yes; retargeting, no. So much user time is spent, for example, on a few big sites which have enough data within their own siloes (based on users' behaviour and topics of interest), they can target pretty well without relying on external data. The big video sites, social media, Amazon/eBay/etc. And then there's a big layer of smaller sites who can inherently target because they're already specialist in nature. The losers in this scenario aren't really the brands, they're big generic sites such as news media who don't have any way to acquire targeting information on their own.
