And there are many thousands of correlations to be measured an watch - thousands I tell you.

This is the killer factor that Tedster has identified. Because, if it's true, and I believe it is, Google has cracked SEO wide open. No-one can SEO a site with any reasonable certainity of success. The variables, and the interactions between them, are so massively huge that no mind can work out what is going on. Only a computer can do that.

Google's long ago advice of publishing sites that are useful for the end user have now become true. Gaming the system is now pointless because "the gaming" now has no guaranteed result.

The problem I see with the SERPS at the moment is the huge bias Google is giving to the "big" sites.
