Facebook Inc (NASDAQ:FB) shares appear to be a great deal more comfortable at current levels after a steady post-IPO decline.

(Unfortunately, the words of The Telegraph's Media, Telecoms and Technology Editor Katherine Rushton, uttered shortly ahead of the IPO, will live on in infamy: "I would expect that the share price is going to climb quite substantially and probably stay at quite a good level for a few years"). 

No doubt, investors in the stock will be hoping that the latest ComScore analysis will restore confidence in the company's business model.

Research from ComScore notes that marketing on Facebook influences consumer behaviour and leads to increased purchases for the brands that leverage the social-networking site.

"The Power of Like 2: How Social Media Works," looks at paid advertising on Facebook as well as earned media exposure - meaning mentions of the brand made by Facebook users in status updates and the like.

Facebook said the research shows that 70% of ad campaigns will get advertisers a return three times what they put in, and in nearly half of all campaigns, Facebook ads get companies $5 for every $1.
