Full study here: http://www.sudorank.com/case-study-bing-yahoo-useful-think/ I'm basically wanting to start a bit of a "Bing / Yahoo" chat. No one seems to be bothered with the Search Alliance but I've had some pretty good results from Bing and even more so now Yahoo is art of it too. You just have to know exactly what demographics and search keywords you're after. Sure, the traffic is much lower than Google but the conversions are much higher. Anyone else noticed Bing / Yahoo is traffic is older / more affluent? Anyone else optimise some of their campaigns for Bing / Yahoo traffic only and get results?
