A week after it began shifting to Bing for its search results, Yahoo says it has finished the transition--at least for its main search results in the U.S. and Canada.
The move comes more than a year after Microsoft and Yahoo reached a deal to partner on search. There is still plenty of work to do as the companies work to shift the more-complicated paid search part of the business and to continue the move internationally.
In a blog post, Yahoo noted that Bing is now powering Web, image, and video search for both desktop and mobile searches.
"The speed in which this was completed is a testament to the great work and partnership between a number of Yahoo and Microsoft employees, the ranks of which are numerous," Yahoo senior vice president Shashi Seth said in a blog post. "With this week's milestone behind us, Yahoo will continue to drive technology innovation in the search experience to bring more value to users and advertisers alike."
Seth also said that Yahoo is working to figure out the new business model for its BOSS (build-your-own-search-service) program, one of several Yahoo search businesses that is being reworked or scrapped in the wake of the Bing shift.
The plan is to also move Yahoo to Bing for paid search this fall. However, both companies have said they are willing to postpone that until early next year if it seems the move would disrupt the all-important holiday season--a point that Microsoft search executive Satya Nadella reinforced Tuesday.
"We continue to work hard on the migration to AdCenter, and are optimistic about completing this phase later this fall," Nadella said in a blog post of his own. "As we have said all along, our primary goal is to provide advertisers with a quality transition experience in 2010, while being mindful of the holiday season."
