Jakob Nielsen has a list at http://www.useit.com/papers/webwriting/. 
His eyetracking & usability studies generally find that online 
readers scan rather than read (partly because monitor legibility 
isn't as good as print legibility)

To summarize, he recommends
* Ultra conciseness
* Keywords upfront, especially in headlines
    Nielsen said the BBC sets a good example - http://www.bbc.co.uk/
* Use numbers, not number words (e.g. 13 days not thirteen days)
* Use visual cues like bullet points, bold face, section headers - 
more than in print

Other sites make similar reccomendations, but Nielsen has data you can cite.
