WORLD - ALL

In December 2005, Google began to roll out what they called the "Big Daddy" update, and by the end of March 2006 it had been fully deployed in all of their datacenters. It wasn’t a normal update, which are often algorithm changes. Big Daddy was a software/infrastructure change, largely to the way that they crawl and index websites.

With the addition of this document to their website, the people at Google appear to be trying to frighten people away from search engine optimization altogether. Although they say that "Many SEOs provide useful services for website owners", they finish the sentence by describing the range of what those useful services are:- "from writing copy to giving advice on site architecture and helping to find relevant directories to which a site can be submitted".
