Microsoft has posted some FAQ’s and their respective answers in an update on its Search Alliance with Yahoo. There’s not a ton of new information, but, there are no doubt plenty of questions surrounding the transition, scheduled to get underway in time for the holidays.

One question Microsoft took on was that of ad positioning between the two search engines. "Your ad rank on Yahoo! and Bing search engine results pages will be the same," says Microsoft’s Carolyn Miller. "Similar to Yahoo! Search Marketing, adCenter determines ad rank based on several factors including the amount you bid, your ad’s relevance, and your ad’s click-through rate."

"As a result of each company continuing to own its own consumer search experience, there may be variances in the number of ads that are displayed in each location on the page. Bing could display three ads at the top of the page and two on the right-hand side, whereas Yahoo! might display two ads at the top of the page and three on the right-hand side for the same search term."

You can see answers to other questions around timing, preparation, and account history here. Microsoft also has the Transition Center up to provide further updates, and advertisers will also receive significant updates via email.

Yahoo has issued a couple of its own updates in recent weeks.
