A few years ago I had a site that I had built that was about two years old. All of a sudden it started to get good traffic from google and I started making money from it. I decided to hire a freelancer to do a bunch of directory submissions for me to hopefully get it to perform even better. It basically killed my site. I went from about 200 hits/day to 10-20 hits/day. Now its about 5 or 6 years old. It's only a PR 1. I get about 10-20 hits per day. If I totally messed up my site by having someone do a bunch of directory submissions, couldn't I theoretically do the same to a competitor to drop them in the rankings? What would you suggest I do now to revive my traffic with this site?
