hello guys, i am having a hugeee trouble with ranking a new emd site. I purchase high pr blog network links from bhw. Also i do social bookmarking, web 2.0 and everything you can think of for link diversity. the sites sits on page for 1 week and than gets sandboxed. Competition is medium and low. but the problem is the sites get sandboxed. Not found in first 50 pages. I am getting crazy. Can the problem be the articles on those sites are unique but non readable content? Do you think the reason is that? Also how can i solve this problem? Buying an old expired domain can solve this??
