I think you could be a lot more successful if you didn't use the cover creator and made covers either yourself or had a worker do it. The cover creator really is a piece of shit. What I have been doing for my olddude style bundles is have a basic template, change the stock photo and title. Nothing too fancy, but still not using the cover creator.
Thank you. I changed it now and use Photoshop covers. A simple template with title and authors. It looks way better. But to see a reaction I have to wait a few days again.
My books always do a lot better when they're 10,000+ words. You might be better off having him write more in one story. Amazon knows when you're just spamming, and they are less likely to promote your books. Quality over quantity is definitely true with KDP.
I also have full books in stock.
Maybe around 20% are less then 10,000 words. Most are between 50,000 - 100,000 words.
I don't think Amazon is making a difference between my books and other books.
Quality is not possible to measure for Amazon. How should they do it? The only way to see if the content is good are the sale figures. If you have a nice amount of sales, Amazon will advertise it. If you don't sell it, yeah, try to find the book after a few days...
Also how could Amazon know, that I am spamming? Where is the difference between me and a publisher, who is uploading his stocks? I don't think that is the reason.
Also my German books doing still well, but are actually only short stories (maximum 3,000 words).
There is something, but I didn't figured out yet.
