Have you controlled the Robots yet?
While some search engine agents may not even look for a robots.txt file in the root of your Website domain, the majority do. With this in mind, the presence of this file is vital to controlling the robots and directing them to look further in and beyond the root. It is also the best way to immediately stop the indexing of information you would rather NOT allow to be seen, like site development areas that aren't yet completed. And don't forget to add META tags to each document's headings too, in order to control the robot one level further!
