Hello everyone, today I saw really interesting thing. One guy is building backlinks to non-existing pages (~10 pages). For example his site is http://www.loseweight.com/ and I see he is building links to http://www.loseweight.com/keyword , but when I try to check that page I get: error 404 - page not found. Then I check that page backlinks in yahoo site explorer and I see more than 200 backlinks (most of them are from article directories, web 2.0 pages and so on). So, what is the secret to build backlinks to non-existing pages?
