Basically it works like this:
On amazon up they put an image or other code on their page that generates a random id and stores it in a cookie.
When you're on Facebook the id is passed back to Amazon which can generate an ad based on your history.
It works because the resource loaded on fb and amazon originates from the same domain. Eg. 3rdpartyretargettingadnetwork.com

- jrochkind1 13y agothank you, this is super interesting.
- jrochkind1 13y agoMakes sense. Will disabling third-party cookies, as per relevant configuration in Chrome or Firefox, make this impossible?
- rlvesco7 13y agoI used to think this was the case, but I use chrome in incognito mode ( and only for fb!) and I'm starting to get retargeted ads. I suspect they are using some sort of 3rd party on the backend. Moreover, it's not only ads now ... I'm also seeing suggested groups that seem eerily creepy ...
