How to shine in the dark (III)
Investigating a little more about the synopsis, I've found a curious tool: https://kindlepreneur.com/amazon-book-description-generator/
They "assure" that authors who use it to generate descriptions sell 15% more average. We'll have to try it then...
Apart from that, a couple of interesting things about synopsis.
When the reader accesses the page of your book, the description is not shown fully, only the first 4-5 lines are visible. Those are the ones that have to give the reader a reason to click "read more" and access the full description.
With the kindlepreneur tool, we can play with the format and size of the text, highlight keywords, and so on.
