Buuuut.... The flip side is that all these mechanisms are unreliable. They might match your phone up with someone elses laptop and you'll see ads for stuff they searched. They might get your location wrong by 1000 miles and suddenly all the ads are in French. You might have clicked no to a cookie banner so now you get to see ads for ED medication despite definitely not having a use for it... Advertising is all a numbers game, and they just aim to be mostly right most of the time.
