Facebook ramps up advertising across news feed and mobile Since the company's IPO announcement, which could see Facebook reach a $100bn valuation, there has been great speculation as to how the social network would boost its revenue figures in a bid to please Wall Street. Despite money generated from advertising accounting for 85 per cent of Facebook's revenues last year, and its net income in 2011 reaching $1billion, the company will have to radically change the way it cashes in on its users" data to make good on its valuation, says digital agency heads, who see these changes as just the beginning. Facebook has also rolled out Timeline, its new profile page, to brands such as Manchester United and Burberry, in a bid to allow them to chart their entire commercial history in one place. Manchester United, Burberry and Dove, have all updated their brands page on the social network to the new style, which until now has only been reserved for Facebook users. The new layout, which allows users to share their entire life history in one scrollable page, is becoming compulsory for the site's 850 million members imminently.
