We want webmasters to know that the Yahoo! Site Explorer team is planning tighter integration between Site Explorer and Bing Webmaster Center to make the transition as smooth as possible. The information that you provide about your website and its structure using Yahoo! Site Explorer has been extremely useful in helping us maintain the freshness and relevancy of our search results, and as you know, it helps ensure that your website gets great search traffic.
Later this week, organic search listings on Yahoo! Search will start to be powered by Bing in the US and Canada (English) markets, and webmasters should begin familiarizing themselves with the Bing Webmaster Center tool.
However, you should continue to provide your site information to Yahoo! using Site Explorer, because in many parts of the world search results will continue to be powered by Yahoo!ís systems until the full transition is complete for all markets by early 2012.
I wonder if they have something up their sleeve at Yahoo for Yahoo Site Explorer when the transition is completed.
