The shift towards closer integration between paid, owned and earned media will accelerate in 2013. As social networks look for ways to monetise their audiences and brands search for more effective ways to engage consumers, there will be increased growth of paid-for social advertising. Facebook may see the lion’s share of advertising revenue but will need to tread a delicate balance between consumers’ and advertisers’ needs. Expect to see plenty of changes around the News Feed, ticker and notifications. Expect changes to the EdgeRank algorithm and key application programming interfaces. After all, if you are only "1 per cent done", there is plenty of change ahead.
