I had a discussion about high-end coffee machines and looked one up on phone (not buying one!). Only FB app on phone is WhatsApp. Went on computer (guest mode on chromebook) to Facebok and I saw the very very very first high-end coffee maker ad in my life. Any plausible path?

That's my guess: that there is some fingerprinting going on and all my devices are linked to my Facebook account. (They use same IP regularly). Basically, no amount of privacy options or switches on the platform or separating devices protects against this. https://twitter.com/aarongraves/status/1263625691750436870 …

I would love to get to know if anyone has clarity/information on this? It seems like a really important thing for people to know: forget not being on Facebook, even not being on the same device is protective of tracking via cross-device tracking/IP.https://twitter.com/WolfieChristl/status/1263629657230004225 …

I looked up one brand, got ad for another brand.
It was a very very specific conversation, and I'm actually not in the market for coffee machines. And it was instant. Looked up, put phone down, turned on other machine, saw ad for other brandhttps://twitter.com/robinberjon/status/1263632775682437126 …Show this thread -
All my searches are in incognito mode. I know it's hard to believe, but I actually research stuff like this for a living. I put everything in incognito mode and separated devices and sandboxed Facebook just so I could rule that out. https://twitter.com/adnanchcg/status/1263633265749090304 …

Facebook aside, Twitter should give every woman an extra 240 characters per tweet to say I research all this for a living and I know all the basic obvious stuff. This makes Twitter unusable—my mentions get overwhelmed by kindergarten level “explaining”. https://twitter.com/topquark/status/126364086562236416 …https://twitter.com/topquark/status/1263640865622364161 …

The most likely explanation is tracking by IP/Wifi. The speed with which it happened suggests some sort of automatic retargeting. I would like to know if this is something they disclose somewhere, or if this is known to advertisers or others? That’s my core question.

I believe logging in to many websites risks setting an associable FB cookie. If you want to keep browsing isolated from FB you need to not authenticate bto anyone who might work with them.

The IP address theory seems feasible to me: if you have the targeting infrastructure in place already, just using the IP's recent activity as an "identity" of last resort probably has little down side.

But you use WhatsApp on same phone that you searched for the coffee machine on? So FB via a pixel can associate your search with your WhatsApp account, and via that to your Facebook account wherever you use it from.

Did you somehow miss the part where she got the ad on Facebook in GUEST MODE on a machine NEVER logged into her FB account?
