I also use a hierarchy of links (#location) that clearly shows how URL's relate both to search engines as well as to human visitors.
I have a question / issue with this statement.
Could not two different human visitors have different ideas of what "clear" is?
Take a company that sells car parts.
One person might consider the following as a clear structure:
part type -> Make -> Model -> Year
(all manufacturers of the part appear on the same page)
One might consider this as clear:
part type -> Manufacturer -> Part
(i.e., all parts made by XYZ company on one page)
another might find this more useful:
Function -> part
(e.g., All products that increase fuel economy on one page, or all products that boost torque on one page, or all products for improving the sound system / audio quality on one page)
So when it comes to structure / navigation, how do we know whose version of "clear" to use?
One other thing:
Matt Cutts has said in his videos and interviews that a human site map is a good thing. He has also said that faceted navigation CAN be a bad thing.
So maybe there should be one "left-hand" navigational structure, and an alternative structure for how the site map is laid out?
