What type of data can I pull for a Facebook Custom Audience?

Your social profile is called your social footprint by Facebook. Your social footprint is all of what you do online. People have a million email addresses, but they usually have only had one, two or three cell phone numbers over the past 10 years. So, the best audience you can put into Facebook is someone's name, their address and their cell phone number. Emails help, but cell phones are the most important because that's going to match in their social footprint. DOPE can help you add cell phones or get a list of people with cell phones simply to upload into Facebook, to get the best match rate possible. The average list uploads into Facebook at 35%. DOPE can get you lists that upload as high as 80% plus into Facebook.
