I'm working on a CMS site just now. When the site is done it'll not really have very much added to it. The structure of the pages is final and all the pages have been created, but not all of them have final copy. Is it worth submitting the site to directories and other search engines now before it's complete, in the hope that it starts getting getting some links before Google spiders the site? Or should I hold off doing any of that until after the copy is finished?
