Small metadata mistakes cost weeks
A rejected title means another review cycle. Weak keywords mean nobody finds the book. These are the mistakes ShelfReady catches most often.

FixOnly 4 of 7 keyword boxes used. Each empty box is a search you can't show up in.
Fix"$2.99" and a link in the description. Prices, offers and links aren't allowed.

Questions
Does ShelfReady change or submit anything on KDP?
No. It only reads the fields on the page open in your tab and shows suggestions. You make the edits and press Publish yourself.
Do I need to give it my KDP login?
No. It works on the page you're already signed in to, and nothing is sent to us. There's no ShelfReady account.
Does it work for paperbacks and hardcovers?
Yes. The Details page fields are the same for Kindle eBooks, paperbacks and hardcovers.
Does a score of 100 guarantee approval or sales?
No. It means your metadata avoids the common mistakes KDP flags and uses every keyword and category slot. Amazon still reviews every book.
How do I cancel Pro?
Open ShelfReady, click the Pro button at the top, and manage or cancel the subscription from there. The one-time $39 plan never renews.
