The Distinguished Engineer took to Twitter late on Friday night to announce: "Minor weather report: We pushed 1st Penguin algo data refresh an hour ago. Affects <0.1% of English searches." The original Penguin algorithm change on 24 April 2012 was said to affect 3.1 per cent of English search queries, while last year's major Panda algorithm update affected closer to 12 per cent, so in comparison the Penguin 1.1 update is minor.
The announcement puts pay to rumours there had been several Penguin changes in the last few weeks, insisting this is the first update since the original took effect; the fluctuations in search engine results that have been noticed in recent weeks may therefore be a delayed effect of Penguin 1.0. Like its predecessor Google Panda, the Penguin algorithm change is intended to curb webspam by penalising sites that violate Google's quality guidelines, including those that are 'over optimised' and use black hat SEO techniques.
Fighting spam and scams
Although Google has not revealed any of the specific aspects that are penalised by the Penguin update, the official blog post stated: "Our advice for webmasters is to focus on creating high quality sites that create a good user experience and employ white hat SEO methods instead of engaging in aggressive webspam tactics".
Richard Frost, managing editor at theEword, commented: "While major algorithm updates such as Panda and Penguin 1.0 have caused noticeable fluctuations in SERPs, it's unlikely we'll see Penguin 1.1 making much of an impact. However, a large number of sites are still trying to recover from the original algorithm update and figure out where they went wrong. Speculation in the SEO industry suggests unnatural linking and low quality content are the culprits, but there is confusion as to why some high quality sites have also been negatively affected."
