Has anyone noticed if Yahoo updates their SERP's in the past two days? One of my real estate sites just dropped from #4 to #35 for our primary search term. I can see dropping a few places, but I don't think that 31 sites suddenly became more relevant. There were no recent updates to this site.
I was wondering if the site may have been "hand edited" by Yahoo since it does not participate in the Site Match or other advertising programs. Any ideas, thoughts, or conspiracy theories?
