Title: Following just happened: An hour before lunch I googled and visited websites that sell bicycles. I also visited Amazon during this research. I then bought a bike from one of the manufacturers&#x27; websites. A few hours later I browse facebook and see ads to this manufacturers&#x27; bikes in my newsfeed, via an Amazon sponsored ad.<p>I use one browser (Safari) for facebook exclusively, and browsed the bikes &#x2F; Amazon &#x2F; made the purchase on Chrome. I have different email addresses for facebook, amazon and, well, google.
