I have one question on this method. Lets assume that there are four sites. Call them as A,B,C,D.
A is primary and B is secondary of one webmaster
C is primary and D is secondary of another webmaster.
B and D has reciprocal links. Your method redirects the search engines from secondary site to primary site, then how search engines know that there are backlinks to A from D site as the search engines redirected from D to C.
What I'm thinking is search engines are not going to see those links at all, as all the secondary sites are redirected to primary.
Correct me. If i'm wrong.
