Am I doing it the right way? (stock music review)

Hi everyone there. I am quite new in producing stock music and all its surroundings, but I have been dealing with music for more than 20 years. I am trying to understand how everything works, sweetspots for prices, how to achieve more views and many other questions that many people probably ask often around. I have recently read an ebook about the subject, but things seen to change really fast and what works for someone can be like limbo to others. I would appreciate If anyone could give a word of advice. I have uploaded 7 tracks a week ago, differente genres. Will upload 7 or 8 more next week. Intention is to have 20 tracks before february. Any opinion about directions to follow, production quality, stratetgy to increase visibility would be very welcome.
