One trick that works for me is to write provocatively.
Your first sentence must draw a lot of attention.
Most people won't bother to read your Quora answer if your first sentence is generic.
You cannot just mindlessly repeat other people's answers and expect people to view your full answer.
It doesn't work that way.
You have to come up with a dramatic angle by appealing to fear, disgust, or hate.
I'm not saying you should write hate content, but you should appeal to people's need for justice or revenge.
You have to use strong emotions, and you might be thinking that this type of writing can only apply to certain niches.
No, this can apply across the board.
Even if the niche of the questions you're answering is plain vanilla and completely harmless, if you know how to write in a way that gets into people's heads, you will find a controversial twist or angle.
