Yahoo and Bing working together
Yahoo announced that they are already running tests on Yahoo’s search engine with Bing’s algorithm, for organic and paid results.
They said that these tests will only be seen on a maximum of 25% of the U.S. searches.
Yahoo and Microsoft’s mobile services are slowly integrating, same thing will happen with the search engines during the summer, hopes are that in September/October it will we fully integrated for the United States and Canada.
In this picture we can see search results of Yahoo and Bing working together (the yellow boxes are Bing)
This means that the search Bing’s algorithm will be fully integrated into Yahoo’s search engine, therefore our ranking positions in Bing must be taken into account, since these serps will also be in Yahoo in a few months.
