We have substantial reports from webmasters and SEOs in both WebmasterWorld and DigitalPoint Forums of a major Yahoo Search update.

This update was unannounced by Yahoo and has hit webmasters by surprise. The last update was on July 17th but that update was not as significant as this update appears to be. Here are some of the responses and reactions from webmasters.

Many feel that Yahoo will reverse these changes, at least at some level. But the update began two days ago and the changes are still noticeable.

Forum discussion at WebmasterWorld and DigitalPoint Forums.

Update: Yahoo posted tonight that this is an official update.
