I just recently took interest in my site again. It does not come up within the top 100 results on google. What surprised me was when I checked my site's backlinks, some of them were to spammy/porn sites. Though I had certainly gotten backlinks from sites unrelated to my niche, I know I didn't link to porn sites. This made me wonder if possibly my rank dropped 1.5 years ago from SEO sabotage by one of my competitors.
At this point I am just wondering if it is even worth trying to bring my site back up in the google ranks, or if I should just cut my losses and start a completely new site.
I know that because my site is 2 years old, it's age could help with ranking potential. I just don't know if too much damage has already been done that it would take more work than it's worth to salvage it.
