It’s back! Penguin 2.0
There has been a lot of talk leading up to this fourth Penguin update, and now it’s finally here. Unlike the previous Penguin refreshes (1.1 and 1.2), this one is an update affecting the algorithm. It also will impact many languages, and each language will be impacted differently. According to Matt Cutt’s blog, about 2.3% of English-US queries will notice an effect of this update, though it is still too early for any sites to notice a difference in their rankings if they have been effected.
This update is again moving towards making sure sites are of high-quality, so this update is attempting to only affect those which use spam-like techniques. Such techniques would be things like keyword stuffing, buying or selling links, excessive link exchanging, using automated programs or services to create links, using invisible text, or anything else deemed unethical black hat SEO.
It is still too early for any site to notice a difference in their rankings if they have been effected. If your site practices white hat SEO–all the ethical approaches to ranking properly in search engines–then you shouldn’t have to fear the Penguin.
