5 Penguin, The Penguin 2.1 with spam filtering algorithm, now online

The fifth output of the algorithm confirmed the fight against spam "Penguin" Google is live. This is why Penguin 5 by our chef. But since this update Penguin uses a slightly improved "Penguin 2" second-generation version of Google technology, Google itself called "Penguin 2.1. "Do not worry. We will explain the meaning of numbers below, as well as what this means for publishers.

New release of Penguin live today
The head of web spam Google team, Matt Cutts, shared the news on Twitter, saying that the latest version would have an impact of about 1 percent of all searches:

Penguin 2.1 launch today. Affects approximately 1% of searches a significant degree. More information about Penguin: Another step to reward high-quality sites

The link points to Cutts, also says that penguin was when it was launched. It does not cover anything new or changed with the latest version.

Here are all confirmed to date penguin versions:

2.1 Why Penguin and Penguin 5?
If we talk Penguin 5 in reference to something called Google Penguin 2.1 hurts your head, believe us, it hurts us, too. But you can pin the blame back on Google. Here is why.

When Google started out of his algorithm "Panda" for the fight against low quality content, he called the first single "Panda. "So when the second came out, people called that" Panda 2. "When the third came out, people called by Panda 3 - causing Google to say that the third version, because it was relatively minor, really should be called Panda 2.1 - the" point "is used to indicate how a minor change that he was.

Google finally - and belatedly - said a press Panda 3 happened, causing the dial to move in Panda 3.0, Panda 3.1 and so on until there had been many updates "minor" we have to resort to go further decimal things like Panda 3.92.

This caused us here at Search Engine Land to decide it would be easier all around if we had only one update confirmed sequentially, so you know when they came. No matter how "big" or "small" one day maybe we'd just give him the next number on the list: 1 Penguin, 2 Penguin, Penguin 3 and so on.

Thank you for headaches, Google
It went well until Penguin 4, typically because Google did not give figures for updates itself. He just said there was an update, and left to us or to attach a number to it.

But when Penguin 4 arrived, Google really wanted to emphasize that he used what he considered to be a major change in the next generation in how Penguin works. So, Google has called Penguin 2, despite all the references to a penguin 2 is already there, although he did not really numbered Among these various updates before.

The update of today, as seen above, has been dubbed Penguin 2.1 - for supposedly this is a relatively minor change to the previous Penguin filter was used. However, if this is an impact of about 1 percent of the requests as Google says, which means it is more important than what Google might consider to be similar updates "minor" Penguin 1.1 1.2 and Penguin.

What Penguin Again? And how do I cope?
For those new to the whole concept "penguin" Penguin is part of the global search algorithm that Google looks periodically for sites that are deemed to be the search results Google spamming but any way still ranking well. In particular, he goes after sites that may have purchased the paid links.

If you have been touched by Penguin, you probably know if you see a sharp decline in traffic starting today or tomorrow. To recover, you will need to do things like disallow bad links or have them removed manually. Filing a request for reconsideration does not help, because Penguin is an automated process. Until he sees what he sees as evil is removed, you do not recover.

If you've ever been hit by Penguin and have taken steps to hopefully fix that today and tomorrow are the days to watch. If you see an improvement in traffic, it is a sign that you have escaped Penguin.
