The strategy behind social retargeting is simple, speak to those users who are engaged with your brand and leveraging the display network, serve up banner ads that incentivize users to join your Facebook, twitter or any other social media channels. You might achieve this through a competition, a discount, or simply by tell them they can. By directing users through to your social media page you are giving them the option to join and thereafter you can communicate to them on a more personal level.
Who do we target?
This is the argument of social retargeting; Do we target everyone who has visited the website, or just those that have completed a conversion or sale? Well there is no one answer fits all, but I would recommend that you start by targeting everyone and see what results it produces, test different retargeting segments and adjudicate.
Josh Strawczynski's Opinion
Retargeting is extremely powerful, but don't limit yourself to one or two strategies, keep pushing the boundaries and try new things, even consider cookie pool swapping or a range of other new up and coming ideas, there sky is the limit.
