Full disclosure: IMPACT is a HubSpot partner -- but that's not why they're included here. IMPACT's landing pages have long been a source of design inspiration. I love the simple layout of the page, from the large headline copy and detailed featured image, to the outline that surrounds the form, to the colors and fonts that are very pleasing to the eye.
Principle of commitment & consistency -- When people commit to something, they're far more likely to purchase from you. That's why getting them to agree to something like a free + shipping offer or by agreeing with something you've said in some way. This is a powerful principle in sales and if you pay attention to some of the best marketers in the world, you'll notice that they work fervently to get your commitment to something, even if it's very small in the beginning.
To be honest, I haven’t really explored LeadPages’ sales page templates a whole lot because I tend to design them myself in WordPress. However, when I created my free Pinterest e-book, I decided to create a sales page-esque landing page, which gave more information about the freebie, much like a sales page would. I also used one of LeadPages’ sales page templates to design it.
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.
