The cost of converting people to sign-up for events, purchase products and register for services decreases considerably when businesses run Facebook advertisements that target existing fans, as opposed to non-fans. Registration acquisition costs can be 44% cheaper, while event sign-ups cost 33% less and purchases are 15% cheaper to achieve.
This is according to a recent blog post on Inside Facebook, who was privvy to data from the social advertising agency TBG showing these results. Over the course of a thirteen-client, 4.1 billion ad impression study, TBG found that targeting Facebook fans was more effective than targeting non-fans when it comes to these specific types of conversions.
