A thread at SEO Chat forums named Do your sites make some huge traffic from msn? Basically, what types of traffic do you get from ranking well in MSN? This of course is very dependent on the competitiveness of the keyword and your placement, but the thread is interesting anyway.
Some figures: - #1 placement bring in 30 uniques per day - #2 placement bring in 2 uniques per day - #2 placement bring in 1,000 uniques per day - #2 placement bring in 500 uniques per day
