Google has been doing a lot of updates to its search engine this year alone. This place has the full run down of the updates that have happened http://www.seomoz.org/google-algorithm-change I'll post a summary of some of the recent ones though: Google panda has effected a lot of non-quality websites, blogs, and forums, but the quality sites seem to be winning the most since these updates have taken effect. But, how are you doing in regards to Google rankings and these updates? Have you rankings increased or have they declined? What are you doing to help get your rankings up to par - if they were dropped. Personally, quality links will always keep your site afloat on the search engines. Without any link backs, don't expect success on Google or any other search engines.
