This is the first time I publish ebook and paperback in KDP Amazon. My book "Budi & Friends Pirates" link https://www.amazon.com/dp/B076VGHRTV
after five days has no selling or promotion report. Of course I joint kdp select to promote my book, but still confuse why there are no report. I don't know what happen, because I am new in this paltform. Can you explain about my problem and give me some suggestion to solving this problem? Hope you all help me.
Also If you can please review my book. That is helfpul for me to improve my book.
Children's books are always a tough sell here, as the genre is flooded with books of high quality, which yours isn't. Parents aren't going to spend what limited amount of money they have on poor quality books. Plus, e-books for kids that age are even tougher to sell. It's not much fun for a kid to read a picture book on an e-reader!
You've set your book as age range 4 - 10. A ten year old wouldn't look twice at it. 3 - 5 would be more likely.
Your illustrations aren't particularly good. Not eye-catching enough.
Your English isn't very good. I couldn't see inside the book for the story, probably because the book is particularly short, but your blurb is poorly written, and even your author bio isn't translated very well. Any potential reader would see that and move on without even looking inside.
As to promoting your book, that's your job, not Amazon's, and definitely not KDP Select's job. If you want sales you have to go and get them, not sit back and wait for them to come to you.
If you came to Amazon thinking you were going to get rich quick, you're going to be sadly disappointed. Authors with quality books struggle to sell a few copies. The rubbish sinks to the bottom of the swamp without even selling that many (once you've sold a couple to friends and family).
