After a series of rumours and speculation, the Web-search giant Google officially confirmed that it has acquired the New York-based yield optimization firm, Admeld.

Google claimed that the acquisition of Admeld will help major publishers to make more money out of the rapidly changing and growing display ad landscape. The Admeld acquisition is a new step in Google's strategy to improve the display ad landscape.

Google and Admeld have refused to disclose the financial terms of the deal but it's believed that the deal may cost around $400 million. With this new move, Google expect to outclass Facebook and other new start-ups in the display ad market.
