Today a site I've been ranking for past 10 months has been knocked off google. It's a hypenated EMD with over 1000 pages of hand written content but very black hat backlinks from tools such as GSA SENUKE. The domain is long tail EMD Name-name-name.org.uk For the past month I was in position 2, but the past 4 days I went up to 1st place woohooo, and today I'm nowhere for my main keyword or the other 80 or so longer tail less valuable keywords I was ranking for. My links although bad had huge diversity with over 300 different anchor tags, linking to all my different pages. Any ideas how I can fix this?
