• Submitted according to KDP file prep and cover wrap specifications.

Results:

• PDP click-through rate increased 11%.

• First-time approval on KDP, avoiding repeated revisions.

• Compliant cover met all Kindle book publishing guidelines.

Conclusion

Optimizing cover contrast and subtitle clarity while following Kindle book publishing guidelines drives higher CTR and smooth submission approvals.
