It reminds me of someone building an elaborate stage presentation and the only guest in the audience is Google. Google's eyes dance around the intricate details of this immense stage you've built and then all of a sudden you realize you forgot one key thing. Actors! Google sneers and exits. Your illusion of authority is revealed and your site plummets in the rankings overnight.
I wonder if buying traffic to run around on these stages we built might make a better show for Google to see?
Anyone experimented with this to perhaps prevent sudden drops in your ranking?
