Successful landing pages?

[Naji Boutros]

I'm adding two pages to my website. One page for distressed homeowners to submit their property, and possibly receive instant cash offers. The second page is for investors to register and possibly receive those off-market listings.

I originally posted a link to those pages, but Bigger Pockets auto-deleted it. 

So instead, I'm going to ask, What are some key elements, tips, suggestions that I need to keep in mind when building out these two pages?
