Same Problem Here.
What I have done?
I have written an SEO optimized content for a construction website named as optimaabuilders.com and when I search in google search console it shows me that my website is indexed already.
What does it mean?
It means that my content is 100% unique. 
What I am wanting or why I am here?
I am here to discuss my problem and that is I have chosen the very low competition keyword (110 Search Volume) and after giving high DA relative backlinks, google is not showing it in the relevant search term. Not even on the 7 or 8th page of the search engine. 
Anyone is here to give me suggestion, how to solve this problem, then let me know.
I shall be very thankful to you.
