The Yahoo! Search Blog announced they have completed an update to their algorithm last week. The update is set to effect how their algorithm ranks web pages and determines which sites are included in the search index.
From the Yahoo! Search blog:
“We rolled out some changes to our index and ranking algorithm last night. So, as you know, throughout this process you may see some changes in ranking as well as some shuffling of the pages included in the index. This update should be complete very soon.”
Index updates are important for major search engines in order to combat spam and reward webmasters who provide relevant content on their website. The update will also allow webmasters to track ranking improvements in search engine results pages (SERPs), as any optimization efforts will now be picked up by the Yahoo! search spider.
Many webmasters have reported seeing fluctuating rank changes during the update, with results settling back to normal as the update completed. The last Yahoo! update was not long ago on May 22nd.
