hi all check this This is a new tools (paid one) ... for keyword bid management http://searchmarketing.yahoo.com/mt/so.php
Y! pushed Search Optimizer hard back in 2004 and got nowhere with it even after paying its salespeople to give the product away for free. The product is rules-based = it won't work in opaque markets like AdWords, MSN, Ask and Y!'s own Panama. Furthermore, it doesn't handle the more complex set of goals and constraints that most advertisers have to deal with. -Shorebreak
