In mid-April, Microsoft announced that the Microsoft-Yahoo Search Alliance was nearly final in the UK, Ireland and France, after announcing the expansion into these countries in February. The ad transition began on April 18.

Today, Microsoft announced that the transition is now complete in these countries.

“Yahoo! Search is really an important part of our business and we have invested a lot of time to make the transition as efficient and as seamless as possible for our advertisers and publishers” sid Jon Myers, Director, Account Management UK and Ireland “Now we can focus on delivering compelling content for our users and customers to build relevant online experiences.

“We’re delighted to successfully reach this important milestone in the UK, France and Ireland,” said Microsoft’s Mark Richardson. “As a result of this transition we believe Bing users will see more useful advertising while presenting advertisers with an increasingly compelling alternative in search advertising. We look forward to this rolling out across the next set of European markets.”

Microsoft has indicated that Germany, Austria and Switzerland would be the focal points for the Search Alliance, following the UK, Ireland and France. The transition on the paid search side has already been completed in North America and India. For organic search, it’s already been completed globally.

Earlier this month, Microsoft announced that it has rebranded its ads for SMBs as “Bing, powered by Bing and Yahoo! Search.”
