I have been using linkauthority for a while now and have been getting mixed results with it. I am currently paying $180 a month to use better domains to place my links on. My problem is that I can spend hours creating 50 odd links (as all the content has to be unique and very readable) yet when i go back a few weeks later a lot of the links are not indexed. After a while when I check the links that have been indexed a lot of the domains have disappeared or my post seems to have disappeared. My question is does anybody know of a similar service to this. I have searched the forums but cannot find anything.
