As many of you know, litigation is forcing FB
to allow users to opt out, at the granular level, from sponsored story units that force users into endorsing products to their friends. Our guess is that it will not make that much of a difference. We doubt that most users will understand or care. It will, though, probably dilute, at least somewhat, the unbelievable focus of the ad unit.
Either way, there’s lots of hay to may in FB, especially mashed up with other channels in retargeting systems. Rock on. Psychographic targeting giveth and taketh.
