This is a fairly new domain, (3 weeks old) I have worked hard on blackhat SEO including Xrumer blasts, scrapebox, but i never ping any backlinks. Two days ago I was ranking 2nd on the keyword I want, I was so happy, but today it's no where to be found on this same keyword. I am not sure but it doesn't look like it's sand boxed, because if I do a search on my exact domain, I can see my site. If i do "site:myurl.com" I can see a bunch for my urls. Why is this happening?
