Last month Yahoo Search had shared that they had begun limited testing of displaying organic search listings from Microsoft on Yahoo! Search result pages. This week they began transitioning the back-end technology for Yahoo! Search in the U.S. and Canada (English) over to the Microsoft platform.
Now, Shashi Seth (Senior Vice President of Yahoo!) has officially announced this on their YSearch Blog:
Later this week, we will begin transitioning the back-end technology for Yahoo! Search in the U.S. and Canada (English) over to the Microsoft platform, and will post an update when the organic search transition is complete for both Web and mobile searches. Keep an eye out for the “Powered by Bing” indicator at the bottom of our search results page, which will indicate that you are viewing listings from Microsoft. And of course, as we’ve stated before, you’ll continue to enjoy the same enhanced Yahoo! experience that surrounds the listings themselves – such as rich results, Search Assist suggestions, site filters, related topic suggestions, and more to come.
It appears that the transition is now complete!
Scroll down to the bottom of Yahho! Search page and you will see: Powered by Bing.
This indicates that you are viewing listings from Microsoft Bing.
Also starting this week Yahoo beginning testing of paid search account transitions.
With this transition there were some hard decisions they had to take and one of which was to stop the SearchMonkey Developer Tools, Gallery and other services. As reported on their blog with effect from 1st October 2010 all these services will be disabled, but they have also promised to bring in some other interesting tools to enhance the Search Experience.
