I want to provide an IT project structure and show page trees in overview pages, but I do NOT want to create empty pages that might be filled eventually. These empty pages spam the search, hide real information, and provide nothing but a waste of time otherwise. The solution should be clear to read (e.g., similar to empty links in Wikipedia that are shown in red color and have the mouseover "This page does not exist").
Any other idea to provide clear structure without spamming the search is welcome.
