KSP is an add-in to Excel 2007 that allows you to take a list of keywords (or your domain) and extract suggested keywords, traffic numbers, demo and geo info, category/vertical info, average CPC, rank, and much more. It has features for you to create pivot tables, charts, etc. I strongly encourage everyone to contact their MSN rep to get a demo.
Microsoft should be applauded for its commitment to transparency. While it may not have the biggest share of the search market, by providing useful tools like this, it will continue to increase its share of mind within the search marketing community.
Let's hope the other bigs take a page out of the Microsoft book and open up their kimonos a bit. Everyone stands to benefit.
