As per recent updates from google it is confirmed by google that on Thursday, September 27th 2012, google have released a Panda algorithm update. This is the 20th update of Panda algorithm. This is a fairly major Panda update that impacts 2.4% of English search queries and is still rolling out. Google has announced a exact match domain update.
As per this updated there are chances of removal of low quality exact match domains from google ranking. From the recent survey it is observed from many non exact match domain site owners their rankings dropped as well.
Exact match Domains: Exact match domains mean domains that match exactly for the search query. For example, if one sells blue widgets and owned a domain named http://www.bluewidgets.com, that would be an exact match domain.
Google confirmed that they pushed out a new Panda algorithm update that isn’t just a data refresh but an algorithm update. Google says this “affects about 2.4% of English queries to a degree that a regular user might notice.”
It also found that there are more updates to come by from google, and google has promised to roll out more to this panda algorithm over coming weeks.
As Said by Google’s Matt Cutts “Google began rolling out a new update of Panda on Thursday, 9/27. This is actually a Panda algorithm update, not just a data update. A lot of the most-visible differences went live Thursday 9/27, but the full rollout is baking into our index and that process will continue for another 3-4 days or so. This update affects about 2.4% of English queries to a degree that a regular user might notice, with a smaller impact in other languages (0.5% in French and Spanish, for example).“
