Whitepapers and eBooks are both longer form pieces of content that form part of a more advanced content marketing strategy. While there are similarities between these two, the most obvious one being length, they differ in several ways:
Whitepapers target a specific niche within your audience while eBooks target a more general audience.
Whitepapers are typically more formal and include more academic references than eBooks.
Whitepapers identify a specific problem and provide a practical solution while eBooks include general information about a topic.
