Landing pages - Quality score relation

[Ciler_69]

I'm pretty new to this whole Azoogle earning "game" and I'm interested about landing pages.
What should the basic look be (website, just tunneling site with few links to the specific offers..) and how does the design and the complexity of the site influence the quality score.
I read in one of the posts: "Everytime I try and run something direct, without a landing page, I end up getting killed Quality Score wise". That got my attention because I don't really understand the connection between the Quality score and the landing page.
So if anyone has some bright ideas or good advice I look forward to reading it.

Thanks!!

I think the most important (if not only) factor is the content. It should be relevant to your ads / keywords, must be unique and good. People say "Content is the king."
