Is this really a mystery? Does anyone even click on Google's sponsored product links? I'd rather hit Amazon for a lower price and get free shipping while I'm at it. That's the contention of the Financial Times, which recently ran an analysis of various products that show up among Google search results. Five out of every six items that appeared in the sponsored items section were more expensive than those hidden deeper in the results, according to the newspaper. And on average, the sponsored products were 34 percent higher.
