This weekend, we have reports coming from WebmasterWorld of major ranking changes at Yahoo Search. It appears Yahoo has started an algorithm and indexing update at their search engine.
Currently there are no "weather reports" with the status of an update at the Yahoo Search Blog, but based on the conversation at the thread, there appears to be an updating taking place. The last update took place in early March, but in reality, most SEOs and webmasters did not notice any changes. So maybe this is the legit update?
Here is some of the feedback from the thread:
I did some more thorough investigating and these results are really bad....
We lost about 50% of our Y! traffic during the last update and we noticed a nice lift today.
Looks like an update to me. See wiki pages climbing to the top for many results. Why do they even want for each term a wiki to turn up. If I want a wiki explanation or information, I'll go to it myself. I find it a step back for search results.
I suspect Yahoo will have a post on the update soon at their Yahoo Search Blog. Since this is happening on the tax day weekend, why not call it the Yahoo Tax Day update? Heck, maybe some of you can use this update as a deduction for 2008? ;-)
