I've been working on an authority website since Last December & all of a sudden, my keywords are no where to be found in the serps, just 2 days ago most of them were on the first page. I didn't change anything or do any notorious backlinking, so I logged in to webmaster tools & on links I see 1 link that seems to come from a scrapebox blast & possibly there is more to come. I didn't do any scrapebox blast(I don't even have scrapebox) so I'm suspecting some dick blasted my site. This is bullcrap btw, doesn't google know that website owners don't have complete control over this? Anyway they just invited lots of spam I hope people start using other search engines. Does this seem like the site's been hit by penguin or panda? Is there any way I can get the keywords back into place?
