I have a site that sales biodiesel processors that has lost it's rank.....I don't know where it stands at this point in time. It was on page 1 and 2 for every good keyword in that niche from the content. I went as far back as 20 pages of Google for the site and it seems to have disappeared completely. My site is still indexed but has lost all of it's rank. What is the deal here? I have seen where people are losing traffic but I have lost nearly 600 visitors per day....Is this normal? The site is about 4 months old and ranked pretty high within the first few weeks and now all of a sudden is gone.
