How do I know whether the content angle of my article is good enough to outrank or not?

[WaliullahWalid]

Search intent is the core of writing and content marketing; its essential to know the best answer.  To analyse search intent, I analyse top 10 ranking pages, see which content format is used on top 10 ranking pages and at last asses content angle. My question is, how can I come up with a unique content angle that's worth ranking and outrank existing articles and what's the points should I consider while implementing my unique content angle.

I am doing the same thing for my website but it is not working. Content with good backlinks is necessary to rank.
