7% of sites
93% of sites
The 7% get the traffic and are doing something the 93% aren't. Where it makes a difference is in the human sniff test EVERY site in the 7% must undergo to retain elite status(in Google's collective mind).
Would YOUR site stand worthy of a top 7% spot? If not right now - what can you do about it?
hint: check out your competitors, you need to find an edge over them all. Ideally that involves alternative sources of traffic too since one can not rely solely on Google anymore(because an eventual kick in the pants by some wild animal seems to be the norm).
