The Benefits of Facebook Connect
First, it facilitates getting mentioned in Facebook usersâ€™s news feeds, which has been the holy grail for marketers because it raises awareness of your business and delivers an implied endorsement.
Second, it provides a treasure trove of user data, allowing Ã¼ber-targeting. You can literally customize the content of your page based on the visitorâ€™s Facebook data, such as his age, gender, location, likes, dislikes, relationship status, even networks, groups, and pages heâ€™s joined â€“ or â€œfanned.â€ As a simple example, if you know a visitor is a fan of the band U2, you can highlight your U2-theme stationery, T-shirts, dog bones.
