Facebook uses this to track your browsing behavior on this website and correlate it with your facebook profile for marketing analysis. This is done by sending data from cookies which Facebook places in your browser when you use their site, as well as other data that is passed through HTTP requests, such as your IP address. If your browser doesn’t support or has disabled JavaScript, a tiny 1 pixel image that you cannot see will be loaded into this page instead. This tiny hidden image makes a request to Facebook’s server that sends them information from cookies which they have stored in your browser when you were on their site. Although data from analytics services such as Facebook and Google is anonymized, there is a possibility for such data to be deanonymized through techniques of metadata analysis. You can opt out of this tracking if you wish by disabling it in these settings.
