So the more google thinks your page is relevant the lower your price will be for each click. My landing pages are 100% relevant but getting google to beleve that is my biggest headache. So far the best I have got on my ad ratings is "good" I have even tried to break off landing pages for their own keywords
example
www.example.com/keyword
www.example.com/keyword/keyword.html
That and relentlessly going thru title tags, meta descipt, H1-H2's made google start to think my site was actually about what my subject is but it only dropped my cpc by 10% of so in some cases.
*frustrated*
