A lot of stuff about GA is optimized for sites with static rather than dynamic content, and Google themselves have this odd notion that people should structure their sites such that there are never pages with revolving content – so, for example, rather than having an index page with the most recent comic, they’d prefer that your index page simply redirect people to the most recent comic’s page. It does make their data model easier to deal with but it’s also a bit nasty from the perspective of users, especially since then it becomes MUCH more difficult for users to bookmark a site or whatever.
