numnum - it was things like tag pages that duplicated category pages - so say you had Brand X and a category named as such and listed across the top. Google is fine with that, but I had also tagged with Brand X, which practically reproduced the category page. I think they think that's an attempt to use internal pages to game their system. So I eliminated those tags.
Also don't go for a home page with loads and loads of links! I don't think they like that at all. I reduced the internal links each page had - you have to think of ways to interlink everything without overdoing it, and the only way is to customise it bit by bit.
