Concise writing, cut into to small chunks and clearly labelled and organized is the style of writing that is most likely to facilitate scanning and let people get as much as info as they need out of a website.
Contrary to popular belief that it should only take three clicks to reach any given piece of information, it is really a easily understandable structure that matters. A clear path to concise info is much better than a confusing short path that packs too much info into one page.
Scrolling can be used to reveal increasingly detailed information about relevant content, or as a way to introduce content and the end of the consumption of this previous piece.
