I signed up for Microsoft adCenter the other day after an issue with Google AdWords.  Shortly thereafter I received an email (text below) describing the Yahoo! and Microsoft Search Alliance.  I’m glad to see that AdWords will soon have a real competitor in the PPC advertising market.  Without competition, it’s easy to let your customer relationships become stagnant.

Dear Keeton,

Microsoft and Yahoo! have now received regulatory clearance to form the Yahoo! and Microsoft Search Alliance in the United States and European Union. This milestone is an exciting step in our effort to give your business a time-saving and cost-efficient way to connect with a larger combined audience of potential customers.

How the Yahoo! and Microsoft Search Alliance benefits you
After the Yahoo! and Microsoft Search Alliance is implemented, you will:

Reach more potential customers: Search ad inventory from both the Yahoo! and Microsoft networks will be joined in a new, unified search marketplace powered by Bing™ , with a combined audience of over 150 million searchers in the U.S and nearly 577 million searchers worldwide.1
You’ll use a single platform—Microsoft adCenter—to manage your campaigns easier and faster. With just one buy, your search ads will reach users on Bing, Yahoo!, and other premium partner sites and networks, such as The Wall Street Journal Digital Network, msnbc.com, FoxSports.com, Facebook, and Buy.com.

What’s ahead
For now, it’s business as usual; there is no change to your account or service. Your ads will continue to serve on Bing search results pages, and you will continue to receive the same great service from Microsoft.

Both companies are committed to making this transition a seamless experience. Our goal is to bring the Yahoo! and Microsoft Search Alliance to the U.S. by the end of 2010, prior to the crucial holiday season, with additional countries following on a staggered schedule beginning in 2011.
As our transition dates approach, we will contact you with information about what to do next. In order to ensure you continue to receive important service updates, please verify your contact information is current in Microsoft adCenter. View our help topic: Change contact information.
