Last week Rene reported on the recent Google algorithm update and this week it seems Yahoo! have followed suit. Last night Yahoo! announced a rebuild of its search index was underway in what appears to be a double whammy for website owners.
From the Yahoo! Search Blog:
We’ve been rolling out some changes to our fresh web data and crawling, indexing and ranking algorithms over the last few days. We expect the update will be completed by the weekend. So, as you know, throughout this process you may see some changes in ranking as well as some shuffling of the pages in the index.
As per usual webmasters can expect to see some changes in ranking while the update is underway. Buzz surrounding the update suggests that Yahoo! now places more weight on the age of the domain, and authority directory listings, but as usual, Yahoo! had made no comment on the issue.
If your Yahoo! traffic or ranking has been affected, let us know via our blog comments!
