Yahoo! has rolled out some changes to their index with fresh web data and updates to their crawling, indexing and ranking algorithms over the last few days.
The updates should be completed soon and may result in some changes in rankings for clients as the updates settle in. If you see a drop in Yahoo! rankings we suggest that you not panic and actually wait. Once the changes settle in rankings are usually restored to previous positions.
For the full posting, see the Yahoo! Search Blog.
