What causes backlinks to disappear when the profile created was still active to begin with? I used a backlink service here. It's too soon for me to say it was a bogus service since I am not a backlink guru by any means! In two days I had one backlink out of 50 but it disappeared the next day. Is that common and should I see others listed since they were up to PR9? What is the best software or website for tracking backlinks?
