This is probably a stupid question but I am going to ask it!
Say you are running a seo campaign for a client, now you want to exchange back links with similar websites but the client doesn’t want to have their website showing links (to visitors) going to similar websites. I could set up a hidden page with links to partners but then who is going to want to exchange links to a hidden page plus the page rank would be very low.
IMHO you should tell the client he can’t have it both ways.
If he wants incoming backlinks, than he should also allow for outgoing backlinks (assuming link trading).
