Why is no one reading my novel??

Do comments and favorites help with the visibility of the story in any way?

I've done ok with ~ 21 average reads in the first week. Just trying to understand how certain books do well. Is it working with the tags and genre?

Of course they do. You might even make the trending list, even if not the top 9, if you have sufficient engagement in terms of reads, comments and favs.
