I've written 
a piece about (near) future trends in SEO, reflecting the current developments in artificial intelligence and its impact on search engine technology. 
In a nutshell: the  technocratic view on keywords and backlinks will lose significance in favor of content value and context. Joei Chan has interviewed a couple of marketing guys and has got 
interesting answers. Worth reading.
It's an interesting question how this development affects the adult market. Discussion, please.
