PENGUIN 2.0

Penguin 2.0, which officially rolled out May 22, 2013

A great deal of speculation has focused on whether Penguin 2.0 targeted the same thing. As previously mentioned, we're still in the early days since its release. But here's a preliminary look at reports from around the web.

2.3 percent of English queries were impacted by Penguin 2.0

 
Penguin 2.0 drilled deeper into websites to look for spam; analyzing internal pages as opposed to just the homepage of websites. This was actually a pretty interesting revelation, because it wasn't previously known to the SEO community that Penguin 1.0 only analyzed inbound link profiles of domain homepages. 

The fact that internal pages are now analyzed means that black-hat webspam tactics such as manipulative link building to internal pages won't escape Google's ever-seeing eye.

PENGUIN 1.1 by Search Giant Google Inc.

Google PENGUIN 1.1

On May 25, 2012, Google unveiled another Penguin update, called Penguin 1.1. 

This update, according to Matt Cutts, was supposed to affect less than one-tenth of a percent of English searches. The guiding principle for the update was to penalize websites using manipulative techniques to achieve high rankings. 
The purpose per Google was to catch excessive spammers, but it seems some legitimate sites and SEOs have been caught with this latest algorithm change. Few websites lost search rankings on Google for specific keywords during the Panda and Penguin rollouts.

It appears anchor text was to blame in these cases, as the links pointing to these sites concentrated on only one or a few keywords while the content of the websites was satisfactory. As the update focused on the quality of backlinks, so the result varied for different websites. 

Google specifically mentions that doorway pages, which are only built to attract search engine traffic, are against their webmaster guidelines. Regardless, many people still use this technique.
