I just got my first sale ever a few days ago. First time in my life when I get money without selling my time. I started at the end of april. I had this idea for an ebook, so I dry tested it using google ads and a sales page built in kompozer. I got some clicks on the buy now button. So, I wrote the ebook, I put it online and the same day I got my first sale. The ebook is advertised on google ads. After that first sale, I expected sales everyday, but I have't got any more for a few days.
Any suggestions on how to improve the sales of an ebook?
(I already changed ads and sales pages a few times looking for the best combination of them)
