I'll try it and post numbers in few months time definitely ... as for inbound links I guess it's same as doing link trades - it depends on witch pages Your link appears. I mean are You buried deep down in directory structure or Your getting index page link. Anyways secondary effect is a possible thing and one I really hope for
(in terms of getting that inbound count in 3 months time).
just one thing is bugging my head ... should I give’em link on index only or keep'em as friends on all pages ... what seams right for You guys!?
