Without proper metadata and category, even the best content won’t be visible. Here’s a practical checklist for uploading and optimizing your ebook on KDP.

In addition to technical upload on KDP, the description section helps index your book with “search-friendly” text.

Before uploading

  • Optimize the title and subtitle for clarity, relevance, and search intent.
  • Write a short, convincing, and benefit-oriented description.
  • Choose the right category: the first category sets the main theme, while the second broadens it.
  • Include 6-10 keywords; avoid overstuffing and repetition.

Upload errors

  • Inadequate or too short description
  • Text in the cover thumbnail that is hard to read or improperly sized text
  • Setting a price too far from competitors’ prices
  • A clean, short, and practical introduction page for the ‘Look-inside’ preview

Test your ebook against Postique’s A4-based layout in both EPUB and PDF view modes, and ensure that the cover is properly sized for thumbnails.
