A white paper is a comprehensive report or guide that provides information and insights into a particular topic or issue. White papers can be used to provide in-depth analysis and insights on a particular topic or issue, allowing businesses to position themselves as thought leaders in their industry.

Overall, a white paper is used to educate readers and present solutions to complex problems or challenges in a particular industry or field. They are typically longer than other types of marketing content, such as blog posts or articles, but more importantly they contain very detailed research, analysis and technical information. They might be more concise to provide more complicated information concisely. 

White papers can be used in various ways, such as to generate leads, establish thought leadership, or to educate prospects about a particular product, service, or technology. They are often used in industries such as technology, finance, and healthcare, where detailed information and insights are important for decision-making.
