An e-book is an electronic book. It's sort of just what it sounds like. For inbound marketing purposes, e-books provide a way to capture contact information from your leads in exchange for a piece of valuable content that helps them make a decision or solve a problem. Providing people with a free piece of information that is educational and informative can help you build a relationship with consumers who are actively looking for your product or service. And capturing contact information from site visitors who are at different stages in the buyer's journey allows you to follow up with them with additional relevant content and offers as you nurture those leads
through the marketing funnel. In short, offering e-books in exchange for contact information allows you to acquire potential customers.
