There seems to be a Yahoo Search update taking place now. A WebmasterWorld thread has discussion around the update. We do not have official confirmation from the Yahoo Search Blog yet, but we didn't have confirmation the last update either.
The first report came in early yesterday morning and since then, many others confirmed seeing an update as well. Let me pull out the key findings from the thread:
- Link counts may have dropped
- Some are reporting canonical issues
- One person reported "different titles and descriptions for singular vs. plural of my main keyword. It's the same URL, so kind of odd."
