Yahoo and Microsoft announced the beginning of the transition of organic search results today, but since the original announcement of the deal, it has been unclear what would happen to the Yahoo Search BOSS and SearchMonkey tools. That is because Yahoo had yet to make up its mind.

Yahoo’s mind has now been made up. BOSS will carry on, and SearchMonkey won’t.

"In the not too distant future, BOSS will provide web and image search results from Microsoft along with other search-related services and content from Yahoo!, such as news," says Neal Sample, VP of Social, Open, & Publishing Platforms at Yahoo. "In the next 30 days, we will announce the specific details about how BOSS will evolve. We are exploring a potential fee-based structure as well as ad-revenue models that will enable BOSS developers to monetize their offerings. When we roll out these changes, BOSS will no longer be a free service to developers."

SearchMonkey will shut down on October 1. That oges for the tool, the gallery, and the app preferences. "Yahoo! Search is continuing to shift from a model where developers build lightweight apps to install on Yahoo! to one where publishers enhance their own site markup to produce similar results," says Sample. "Yahoo! Search results pages will continue to show enhanced result templates from websites’ page markup and structured data feeds along with Microsoft’s organic listings."

Sample also provides updates on various other Yahoo Developer tools here. He discusses the future of YQL, Site Explorer, Maps, Geo, and Local APIs, and MyBlogLog.
