Yahoo! Search blog (www.ysearchblog.com) confirmed on Friday that an index update is currently underway. This follows hot on the heals of Google’s recent Backlink and PR update. A double whammy for many website owners to kick start 2007.

According to Priyank Garg on the Yahoo! Search Blog:

“We are in the process of rolling out some changes to our search results. As usual, you may be seeing some changes in ranking as well as some shuffling of the pages that are included in the index throughout this process. This update began last night and should be complete very soon.

Keep the feedback coming!”

As is the case with all search index and data updates, the forums and communities are alive with feedback, with most of it generally negative. Complaints range from spammy/irrelevant content in the top rankings, to incorrect listings in the SERPs, and everything in between.

At this stage, we’ve actually seen improvements in our rankings on many of our core keywords. So hopefully the update will start to reward website owners using best practice SEO and link building tactics. Why not share how the update has impacted your site’s Yahoo! ranking?
