Microsoft and Yahoo announced today that they have received clearance for their search agreement, without restrictions, from both the U.S. Department of Justice and the European Commission, and will now turn their attention to beginning the process of implementing the deal.

The exact implementation is yet to be announced, but will involve Yahoo shifting their organic and paid search operations to Microsoft. Yahoo will then display primary search results from Bing and enhance them with Yahoo content.

Advertising for both companies will be managed by Microsoft’s adCenter platform (meaning the closure of Yahoo Search Marketing) and prices for all search ads will be set by AdCenter’s automated auction process.

The two search giants have created a web site dedicated to the partnership and Yahoo has implemented a Transition Center for advertisers.

What does it mean for the search industry? To use a silly dinosaur analogy, (because who doesn’t like those?), it means that Bing the Triceratops and Yahoo the Brontosaurus have just combined to become an aggressive Tyrannosaurus Rex that’s going on a hunt for the Google Gigantosaurus.
