I’d like to develop a finite, coherent set of attributes that determine how much information to put on a page (a virtual, scrolling page that is) and that size of that page. It seems like a small enough scope to get scientific about it.
The bookseller site analysis I did was informative (long pages seem to be OK in some contexts, density of text and links are something to look closer at). Some other relevant issues might be:
- Cooper, who says navigation isn’t fun, so make fewer pages with more to do (my personal take here is that interaction design is harder than your usual layout-content-and-links design, so only use interaction design if you can nail the interaction, otherwise keep it simple
- factor in page weight of course (which in turn factors in download speed)
- factor in the time it takes for elements to display (since stuff loading in over time is actually what people experience)
