We’ve been antic­i­pat­ing the complete Yahoo/Bing/Binghoo tran­si­tion for months now and today we got word that it’s finally offi­cial.

Yahoo has completed the process of moving search ad serving for Yahoo! to the Microsoft Adver­tis­ing adCen­ter plat­form in the U.S. and Canada. With this mile­stone achieved, the tran­si­tion of Yahoo! Search Market­ing accounts to adCen­ter is also complete. Now adver­tis­ers have access to 163 million unique searchers and 33.8% of U.S. search queries on Yahoo! Search, Bing and partner sites, with the conve­nience of one account.

Here are some impor­tant points to remem­ber:

  • Going forward, adCen­ter accounts are the only ones that need to be managed in order to adver­tise on Yahoo! Search and Bing.
  • Begin­ning Thurs­day, October 28, Yahoo! Search Market­ing accounts will change to a read-only state. It will be acces­si­ble for the next five months, so that we may view your histor­i­cal data from the past 13 months. Click charges will no longer accrue and no further action is required to close accounts.
  • adCen­ter account support is now managed exclu­sively by Yahoo!
