Yahoo! organic search transition to begin
Later this week, we will begin the work of transitioning the back-end technology for Yahoo! Search over to the Bing platform. This is an important step toward our goal of improving the overall relevance of Yahoo! organic search results and attracting a larger audience to Yahoo! Search, to ultimately put your ads in front of more potential customers.
You’ll want to make sure that you’re prepared for this change, so be sure to check out these tips and stay tuned to the Yahoo! Search blog for confirmation of when the organic search transition is complete.
Testing of paid search account transitions has begun
Soon, you’ll be able to access a transition portal from within your Yahoo! Search Marketing account. This portal will walk you through the simple step-by-step process of creating a Microsoft Advertising adCenter account and importing your campaigns, or linking an existing adCenter account that you may already have.
Before we make this transition portal broadly available to all advertisers in the weeks ahead, we are currently testing it with a limited number of accounts. You will be notified via email once the transition portal is available.
Commitment to a quality transition continues
As we’ve stated all along, our primary goal is to provide you with a quality transition experience in 2010, while protecting the holiday season. We continue to make great strides toward this goal, and we evaluate our progress every day. However, please remember that if we conclude that it would improve the overall experience, we may defer the transition to 2011.
