So where should we add folders to our URLs? I always ask the following two questions:

• Will I need to group the pages in this template together? If a set of pages needs grouping I need to put them in the same folder, so we can identify this by URL.
• Are there crucial sub-groupings for this set of pages? If there are, are they mutually exclusive and how often might they change? If there are common groupings I may want to make, then I should consider putting this in the URL, unless those data groupings are liable to change.
