Matt Cutts Talks about Penguin 2.0 on May 22, 2013 just a few hours before it goes live.
Google has started rolling out the next generation of the Penguin webspam algorithm last night, and the rollout is now complete. About 2.3% of English-US queries are significantly affected. This algorithm update comes a week or so after Matt Cutts announced the upcoming update in one the Google Webmaster videos, you can watch the video here.
There has been significant fluctuation on Google.com (US) as you can see below, most users will actually notice the change in search results particularly in the English language.
It is early doors but we are noticing two major issues that have not been resolved in this update.
Domain diversity or domain crowding has been a major issue for a while and most people (us included) had hoped that this issue would be addressed, unfortunately it looks like that has not been the case. The graph below demonstrates that domain crowding is still as prevalent, there is less diversity which means there is more domain “crowding”.
Here is a good example of domain crowding, as you can see in the screenshot below two sites are almost dominating the first page. It is so unfortunate to see these issues after such a big algorithm update. I reported this particular example to John Mueller and Matt Cutts almost 8-9 months ago and chased them several times, however, it looks like nothing has been done about them.
Exact Match Domain (EMD
Historically exact match domains have ranked higher and based on the data we can see, this issue is prevalent.
