If you're seeing a shift in your Yahoo rankings, you're not alone. Yahoo has announced that it is rolling out updates to its search index.
Writing on the Yahoo Search blog, Priyank Garg and Sharad Verma said, "We'll be rolling out some changes to our crawling, indexing and ranking algorithms over the next few days, but expect the update will be completed soon. As you know, throughout this process you may see some ranking changes and page shuffling in the index."
