I can always tell what my wife is buying for my birthday, I get ads for the stuff she searches for even though we do not share devices, Google seems to make ass

I can always tell what my wife is buying for my birthday, I get ads for the stuff she searches for even though we do not share devices, Google seems to make associations from the IP address. I watched a video review of a drone on YouTube and that was a huge mistake, got slammed with drone ads for weeks afterwards. Watching any video mentioning “Planet X” seems to sign you up for a semi truck full of crazy also.
