What this means is that beginning today, Microsoft Advertising adCenter powers the paid search advertisements on both Bing and Yahoo! owned and operated properties and publisher networks in the U.S. and Canadian markets. Advertisers will operate a single account in adCenter to reach Microsoft and Yahoo!ís audience of 163 million searchers in the U.S. and 15 million searchers in Canada.
This will provide advertisers with the benefit of a combined marketplace through a single platform, creating a competitive alternative in search. Rather than managing campaigns on Bing and Yahoo! separately, advertisers can now reach the combined audience of both search engines by managing a single account, saving time and simplifying campaign management.
Earlier this morning I got an email from Microsoft saying "adios". The confusing part for me was this one:
Now that the transition is complete, you will work with your Yahoo! account team for all your search advertising needs. As of October 25, 2010, your billing and account management relationships have been transitioned to Yahoo!. Your existing Microsoft Advertising adCenter agreement, including your Microsoft Advertising adCenter terms and conditions with Microsoft, were terminated as of October 25, 2010.
