I was searching on Google.com
i put "Six Sigma certification"
On 11 th position i got a site www.jbtrading.com.cn/, Once i clicked page not found.
I checked this site other pages (30,400 total pages), all pages are copied from xxhttp://www.brainmeasures.com/
Even The site www.jbtrading.com.cn/, have copied content along with same URL structure .
example- http://www.jbtrading.com.cn/courses/...ess/index.html
http://www.jbtrading.com.cn/courses/...ent/index.html
http://www.jbtrading.com.cn/courses/...nit/index.html
All these inner pages, design content are from Braimeasures
How can this type of site rank on 11 position, if whole site is duplicate copy of other site.
Please help me, i am very confuse.
