I also share the same thoughts on this 
How to attract more readers?
Using words you don't fully understand is never a good idea. Using fancy words just for the sake of it may be worse. Makes it tedious to read and way less relatable.
How do you attract readers?
Think outside the box. Thanks.
I feel like if you do your work with passion and write because you are happy and because you love writing, you'd get more readers.
Sometimes things work like magic
Just my own opinion 
If you want to use words you don't fully understand, look them up! You can Google words and get their meaning instantly. Then you can use the word properly and feel confident.
Write what you know. It is always a great idea to refine your craft and step out of your comfort zone, yet it is wise to start with research, experiences, and something that has an emotional connection. I think this is the best place to start.
Google is paying $27485 to $29658 consistently for taking a shot at the web from home. I joined this action 2 months back and I have earned $31547 in my first month from this action. I can say my life has improved completely! Take a gander at what I do........ http://4cashbag.ml/

I get lazy with big words. I'm just going to say something like: "Her beautiful silk robe fell perfectly off of her body, down to the floors. Adam looked at her with an intriguing expression....what was it? Was it a coveted expression? His eyes traced along her sides as he bit his lip.
that was off the top of my head.
Okay, y'all should I make a story with this in it?

I feel like it is always a good idea to step out of your shoes as a writer and read the chapters you write as if you are reading them for the first time. This always helps me find flaws in my sentences.
