This is one of my favorite things about LeadPages. For most people, designing a lead magnet landing page on their website is difficult because then you’d have to mess with the coding on your site and could potentially break something. LeadPages makes it mega easy. They have about a zillion different templates you can customize to create landing page opt-in forms, like this one:
Of course, if you're going the paid ad route, you could also use Facebook and Google re-targeting to keep that awareness and interest level high. For example, if you've ever noticed after leaving a particular website, that you begin to see their ad everywhere, there's a particular reason for that. Especially if they've already entered your sales funnel, this is a very powerful way to get them to act.
The first helps direct attention to the goal of the page -- for you to fill out the form -- in a way that's unobtrusive and feels less like a chore. The second gives this page an SEO boost (search engines will have more content to crawl) and assuages any worry from folks who need to know more about a piece of content before handing over their information, all while not distracting people from the chat window.
