Google has announced an upgrade to  their SEO Algorithm from Penguin 2.1 to  Penguin 3.0!

However, some observations indicate that this update may give an edge to white hat hackers who have websites with a natural link building strategy. We have noticed a sudden increase in our websites with natural link building. However, It is too early to come to any conclusions at this stage.
