Use robots.txt to set site-wide rules. Note that credible search engines will follow these rules but these areas are still accessible to the public and can be indexed by bad agents.
Hide or display individual pages with a page parameter.
Hide or display sections, pages, and folders from the sitemap with access. Note that "Exclude Search" in the access menu, excludes from OUCampus search, not search engine search.
