Hi RighterOne, I just Hub published my first fiction. I can only tell you what I did. I am still getting search engine traffic and it is well represented in featured hubs. In my writing, whenever a key character drove a car, I used the full name of the car. e.g. 2012 Rolls Royce Phantom. I did the same for a helicopter, military vehicles and military weapons. That way, those who search for those things might get a look at my story in Google. From what I've been told, fiction is considered to be difficult when it comes to keywords. I also used historical references such as Adolf Hitler, Nazi, The Third Reich, The Fourth Reich. A main emphasis in my story was mass hypnosis, so anything to do with hypnosis went into my story and keywords. Finding keywords in fiction, for me, was like mining. I had to pour over my text and find possibilities. Good Luck, and I will try to find your hub novel and read it.
