Every single one of my rankings fell a few days ago...some by a few places 4 -6 others by 30 - 40, some by alot more. All on the same site. Site structured so each page foused on a keyword. Ive not done any serious linkbuilding, few here and there, never blasted he site. All original content on it. Buiilt a few .edu links to a specific page a few days back...but that wouldnt effect the whole site (would it) Site is about 8 months old, not sandboxed, cant work out whats happened. I've not done anything new in terms if link building so can it be a google dance? Or is it a natural ranking position....cant work it out!!!! Any experienced friends want to tell me what going on and what to do?
