Ask HN: Why do I see ads for websites I just visited in my Facebook Feed?

It feels a little disturbing that after visiting a website like One Month Rails I see ads for that site in my Facebook feed. Is that just an ad program that looks at the cookies I have, or what? Am I being irrational by finding this troubling?

It is all part of targeted advertising by tracking your online behavior and it is not irrational to feel creeped out by this.

A few months ago, Facebook partnered with some of the largest data companies such as Acxiom, Blue Kai, Epsilon, and Datalogix to help improve their targeting. (https://www.facebook-studio.com/news/item/partner-categories...)

One way to help prevent targeted advertising and companies collecting behavioral data about you is to use a browser plugin called Ghostery. (http://ghostery.com)
