Big news this week for the PPC industry. Jeeves announced that it will sell PPC ads ontop of ads fed by Google. MSN is officially the last of the first tier engines to serve it's own PPC ads. At the moment, MSN's sponsored ads are served by Yahoo Search Marketing (formerly Overture).

Microsoft next week will announce that an invitation-only test of MSN Keywords will begin in October with 500 advertisers and search-engine marketing specialists. The service will move MSN closer to how Google handles advertising, by using live auctions of keywords. MSN Keywords is one tool of a broader set of new advertising services called adCenter that Microsoft is building on MSN. Microsoft executives say they hope the tools will allow companies to tailor advertisements by giving them more detailed information on web users than is currently available.
