be serious about your site
The problem being we don't know what "improving" our site means in their eyes, especially if that site was fine to begin with. The more "serious" my sites were (as in putting effort and sweat and soul into it), the more pandalized they got.
For example, removing thin pages like categories, comments or tags pages is not for the benefit of users, but their index. Now if they said "W3C compliance will give you bonus points", "Don't use too many affilate links", "Don't use too many slow loading widgets" or "Don't put ads above the fold", it would be clear, and an actual force for improvement on the web.
