Any auto link exchange will get you trouble on the short / long run, better to move to manual link building.
Unfortunately I found linkmetro.com to be very inefficient: - You put the links, and the other party never replies so he gets 1 one-way link for a long time. - You get listed on junk pages full of mixed pages I found this process best - First submit to quality directories get your pr to 4 or more - Then contact related sites owners directly and arrange for link exchange other option try to buy a link there Hope it helped
