> Amazing how much thought goes into something as simple as a URL.

As a rule, a great deal of thought should go into any website's URL structure. It's one of the most painful and costly things to change later, especially if search traffic is significant for the site.

It is definitely something I forget to think about and when seen at the scale of the BBC it's an amazing thing. Might have to start thinking about URL structure a little more now and this is a great resource to get me going!

Your url structure is a part of your ui.
