✍️ Self-Publishing (eBooks, Guides)
What it is: Self-publishing involves authors independently creating, publishing, and distributing their written works, such as eBooks or guides, without the involvement of traditional publishing houses.
This process allows authors to maintain full control over the content, design, and pricing of their books. Platforms like Amazon Kindle Direct Publishing (KDP) and Gumroad facilitate this by providing tools for authors to publish and sell their works directly to readers worldwide.
Why it's compelling: The self-publishing model democratizes the publishing process, enabling writers to reach global audiences without the barriers typically associated with traditional publishing.
The eBook market has experienced substantial growth, valued at approximately USD 22.45 billion in 2024 and projected to reach USD 36.22 billion by 2034 . This growth is driven by technological advancements and shifting reading habits, indicating a robust demand for digital content.
