They don’t have to collect them as in saving them, they just have to collect information about activity that would interest marketers who buy the data. “Searched for dishwashers”… “Ordered dishwasher”…

Then the marketers could process the data and go, Lovable Sidekick searched for dishwashers but didn’t buy one, maybe he’s still looking, let’s send him ads for dishwashers. Or, Lovable Sidekick bought a dishwasher, let’s not waste ad impressions showing him dishwasher ads, let’s show ads for dishwasher detergent. I mean, if I were part of that whole circus that’s how I would try to approach it.
