The landing page is a scalable way to see if what you're saying resonates with your target market. You will need to generate traffic, either manually or via ads. With an LP, you can see if your message (and how you phrase it) is something that someone will proceed down the funnel for.

It's not going to get you anywhere on its own. It's one step of the puzzle, but an important one.
