Last week the new version of Google’s Penguin algorithm went live – Version 2.0 (Penguin Update No. 4). There was much discussion on this topic beforehand and although there is often some nervousness with updates like these, it was not as bad as many had predicted it to be. Again, the update was announced in detail by Google and Matt Cutts.
In order to show the largest changes, I left out the “small” domains and have taken a closer look at only the SVR-losses of the 1,000 strongest USA domains (acc. SVR) in comparison to the previous week.
The complete list of the absolute percentage changes is accessible in the tool, but this way we avoid domains with extreme losses, but only moderate rankings, in the following table.

Naturally, one needs to keep into consideration that the changes can also have other reasons than the penguin update, but even Christoph believes that cheapoair.com provoked it with a bit too much unnatural link building:
Other domains, like elearners.com for example hit it hard regarding the rankings and visibility:
In total there was a considerable amount of movement, but the changes were not as strong as other updates. SEOlytics users could already identify the changes even more closely last week directly after the update hit within the daily SEO monitoring and using the Daily Visibility Rank (DVR).
What we also noticed during the data analysis is that in comparison to the previous week, the amount of rankings from the same host was finally reduced. Sometimes pages were almost completely occupied by the same domain; these SERP-Clusters seem to have now been resolved by Google. Meanwhile, we have reached roughly the same level regarding the diversity from 12 months ago.
Change of ranking hosts in comparison to the previous week:
What we found extremely noticeable with the analysis of the penguin data in comparison to the previous week and next to the addition hosts, were the impressions from Google Books. In comparison to last week the impressions (mostly on page 2-5) increased by 500% in some countries.
All data was calculated after the Penguin Update and the evaluation is based on the SEOlytics USA SEO research database with ~100M rankings.
