I am needing true help getting out of what I think is the Sandbox. I have a pr2 site aged for almost 3 years , with higher authority ranking than most competitors on the first page for my keywords. I was on first page ranked 3rd or 4th position every day for the past 9 months and then all of a sudden my rankings dissapear for my keywords except for searching for the domain itself. I do realize my business is very cut throat and I am willing to believe a competitor sabotaged me probably as it has happed many other times in other ways. My business relies on my site appearing , can anyone help me?
