Dennis Mortensen has posted on his VisualRevenue Blog that “Microsoft is the best converting search engine today!”

He “conducted a study on 15,014,924 visits across multiple global commerce web properties in Q4 2007, with approximately USD 1.2 Million in Paid Search advertising spend.”

This Independent research backs up the study we did last year with NNR which concluded that Live Search would convert 70% (actually we revisited it and it’s now 80%) higher than than other search engines on average.

Net/Net - Although the traffic from Live Search may be lower than on Google and in some cases Yahoo! it still pays to advertise on adCenter from an ROI perspective.

And if you want more high quality traffic, how does 20m unique users and 330m pageviews sound?
