See my post #25. I believe like Facebook, they will track where you go on internet - for example garden sites, they will read your email for key words like vacation, reservation, etc. and provide that information to advertisers.
Interesting how this ties in with “behavioral internet pricing/marketing...
I wouldn’t have FB if you paid me and just went into the computer to delete everything googlish.
Facebook shows me ads for the most outlandish things at times. Why would I want a kitchen makeover? Oh yeah, probably because I posted a food recipe to Facebook at one time. Maybe the Ford ads are random because I don’t recall ever having said anything about Fords (the last one I owned was over two years ago).
