Struggling to get Book reviews

A book I created has sold over 1200 copies already.

Can you guess the number of ratings/reviews I got for that book? Just 19. :/

2 of ratings are 1 stars without any explanation. How will I know why they disliked it so that I can improve the book to their liking?

I went back to my teenage and early youth and I realized that I never reviewed or left ratings for a majority of things I brought online. I just enjoyed them, forgot to thank the person who made it and delivered it to my home. :/

However, if I received a defective or bad product, oh my, I would jump online in an instant and leave a bad review! (honestly have done it only a handful of times in my life!)

But now I know the eagerness that product makers have when creating something. They want to hear feedback about their product.

Due to lack of reviews from real users, several companies employ other companies to inject artificial reviews/ratings in order to boost their books and thereby its sales. You might have noticed all those reviews without the "Verified Purchase" tag. As a company policy, I stay away from this practice.

If you would be so kind to spare a few minutes, please consider leaving a review/rating for the products you are enjoying everyday. It would mean the world to us makers/publishers/creators.

Feedback helps us improve our products so that we can serve you better.

Ciao :)
