After more than month, Google rolled out another Panda update. Specific details of what changed were unclear, but some sites reported large-scale losses.
Google declined to share any specifics about what types of sites, pages or content this update targeted, instead only sharing the company’s default statement:.
We’re continuing to iterate on our Panda algorithm as part of our commitment to returning high-quality sites to Google users. This most recent update is one of the roughly 500 changes we make to our ranking algorithms each year.
Among the latest victims of this week’s Panda Update 2.5, some unexpected surprises: popular tech blog The Next Web, blog aggregator Technorati, and NBC’s The Today Show. Winners include Google’s own YouTube, along with Fox News and several other mainstream news sites.
Apparently, that patented SEO process that Business Wire just announced isn’t much help to the company. It was listed among the victims, along with PR Newswire.
There also appears to be some change in how press releases effect ranking that we are exploring.
