Google’s primary revenue source is AdWords, meaning ads served on their own properties, the bulk of it being in Google Search and most if that is contextual, most ads being served based on the search you’re making. Google doesn’t actually have a problem in serving contextual ads on their own properties, since they have plenty of context. The problem is with AdSense since there advertisers need some sort of user profile, plus in the EU bidding exchanges are in jeopardy due to the GDPR.
