And you checked that none of your competitors slammed you with a bunch of spam backlinks, (google bowling), right?
Maybe someone files a spam report on every site that climbs to the number 2 spot in the rankings for your keyword and this triggers a manual review.
That's what I was thinking. Would love to say that "great minds think alike," but my mind ain't great, so maybe you are in trouble aristotle...
How optimized is the anchor text in your backlinks?
And it's a review site, right? I see all sorts of review sites ranking very well in the SERPs (usually right underneath the manufacturer's site).
