The point is, if you had the same rankings in Google or Yahoo! your income would be substantially higher than what it is now. The CTR in organic listings is dismal to say the least. I am thrilled to hear you are monetizing your site with MSN traffic - it is just if their organic listings were better, your CTR would be three times what it is now.
Not for lack of trying, friend. Everyone would love to have top Yahoo and Google rankings to go along with MSN, but it eludes me. So I hope for a return of the MSN ranking I've enjoyed for over a year. Hope springs eternal.
