I see part of SEO industry and Webmasters communities are impressed of the effectiveness of latest Panda and Penguin algo updates to kill "traditional" spam mentioned in Google quality Guidelines [support.google.com...] .
However I have noticed that Multi Domains Crowding "Smart Spam" has emerged victorious regardless Panda & Penguin.
Allow me to clarify what I mean by "Multiple Domains Crowding (which is something entirely different than "Google Domain Crowding problem").
Multiple Domains Crowding Spam: Its a specific spam technique to own more than one top position on first page of Google SERPs for the same search term by several different domains you own or lease.
I prefer not to talk about "How To" of the said spam method as its not my mission to teach how to spam Google.
For example a kind WebmasterWorld member has sent me some search queries related to niche "Assisted Living" which illustrated how at least 3 different domains of same owner are within top 10 results of first page of Google Serps for the same search query. Such spam method is pushing possible valuable sites of honest webmasters out of top ranking on Google Serps.
I wish to mention that Multiple Domains Crowding spam isn't something new. In fact it has been know among Black Hat SEOes for several years. It is sad and discouraging for White Hat SEOes and Webmasters to see Google Websapm Team unable to win the war against Multiple Domains Crowding Spam and neither Panda nor Penguin have been able to solve the said spam problem.
And I don't see any effect on Multiple Domains Crowding spam by current Google algo rollout which Matt Cutts has announced recently, unfortunately.
