Broken or malformed ebook link
Navigation · E-LINK
Definition
A link inside your book points to a missing EPUB file or anchor, or an external URL is missing its protocol.
Why
- Internal href to a removed chapter or deleted id.
- External link written as www.example.com without https://.
- Wrong relative path after moving files between folders.
- Spaces or unescaped characters in href that break resolution.
Impact
Often a warning on KDP; still review before upload.
