Ask HN: Good resources/articles on laying out a landing page?

Hey all. I'm at the point I need to start creating landing pages as part of my customer discovery process. The goal of each page is to measure interest for a particular feature I could implement in my startup's site.

I know which features I want to test, but I'm foggy on exactly how to go about it. In particular:

1) How should the elements of the page be laid out? 2) How much/little information should I pitch to the user about the feature I'm measuring for.

I'm just creating the wireframes that I can pass on to my designer, who will make it pretty. So I really just need a little guidance for the actual content.

Any advice or links to resources?
