"With Yahoo and Google consistently ranked the No. 1 and No. 2 most frequently viewed sites on the Web (comScore said Yahoo had 136.6 million unique users in December 2007 while Google had just fewer than 130.0 million) it pays to get noticed on these engines. It also saves money, said Tara Lamberson, VP-marketing and strategy for interactive agency MindComet, because people are more likely to click on an organic search link than a paid search link, especially if the same company's links show up on both."
