The fifth Penguin version of the second generation, called Penguin 2.1, is now live. Did you get that? Yeah, that’s a lot of numbers and everything, but the most important thing you need to remember is that it’s NEW. Matt Cutts confirmed the latest Penguin algorithm update is alive and thriving. It’s the fifth version of the algorithm and uses Google’s second generation penguin technology. Hence, Penguin 2.1. SEOs and marketers should always be aware of when the latest update of any Google search engine technology goes live so they can understand why their rankings suddenly changed or why their site is not performing as well as it should. The good news is that the change was probably not felt by many, as if affected roughly 1 percent of inquiries, according to Cutts. But it’s important to be in the know, nonetheless.
