I run a site that has some of the site pages accessible through the site's main navigation. Then, there are 50+ "state" pages that are accessible to a user if they click on a specific state on a flash map on our home page.
What are the SEO implications of having the site set up so that a significant portion of the pages are not accessible via the main navigation of the site? I know that Google has indexed these "state" pages previously, as they will pull up in organic rankings occasionally. But, would they rank significantly better if we organized the site differently?
