Clickbank Landing Page Samples?

Good morning everyone.

What is the best way to setup my landing page for SEO with Google, and also to be able to have a decent conversion.

I've thought about having just a opt in page where I give away something in exchange for their email but I'm not sure how well that will rank with Google.

Does anyone have any sample sites I can take a look at? I just want to get an idea of what works and what doesn't..

Thanks for any help.
