A: Facebook retargeting is where you serve Facebook ads on Facebook to people who visited your web site and left without converting. This is a whole new retargeting channel, made possible through Facebook's recently launched Facebook Exchange.

With ICFX™ Facebook retargeting, a business adds our "site tracking tag" to their web site code. This tag is completely invisible to visitors and places a unique "cookie" in their browser that lets the user be anonymously identified as having visited your web site. The users cookied in this way make up what we call a "retargeting list".

Once you've created a retargeting list, you can use ICFX™ to create Facebook ad campaigns that will reach those people on Facebook in ads on the right sidebar or in their News Feed. When your users see these ads, they are reminded about your service and will return and sign up or convert in some way. Facebook retargeting's main advantage is that Facebook ads are much easier to create than banner ads and Facebook sidebar CPMs can be up to 60% lower than web CPMs.
