Hi friends, Today I analyze this site's backlinks: sneakernice.com that I detected some backlinks (high quality) of this site are following: http://www.cpatlanta.net/28/ http://www.golfleecreek.net/28/ http://www.quebechotel.org/28/ http://www.a-bailbond.org/28/ http://www.nosqlwinter.org/28/ . . . (many more sites like above) when I clicked these urls, all these urls show me the same site contents and html code as the money site: "sneakernice.com" except for the main domain changed, For example, the www.cpatlanta.net/28/category1.html contents and html code are same as www.sneakernice/category1.html contents and html code (other pages are same 2.html=2.html, 3.html=3.html, except for the mail domain changed) the www.golfleecreek.net/28/category1.html contents and html code are same as www.sneakernice/category1.html contents and html code (same as above)... This is not 301 redirect I think, but what type of these backlinks are? Whole site copy or any other new type backlinks? And why all the second tier categories are "28" HOW TO GET THESE TYPE BACKLINKS? Any seo expert friends can tell me? Big Big Thanks!!!
