Skyscraper technique can build unique content using the loopholes of the previously posted content. But its hard as it needs extensive research in the topic to succeed. If you are doing it then are you hiring anyone and/or team to do it. Or you guts do it yourself. I am little bit confused right now, I want to build unique content in a competitive niche so should I hire someone?
If you are doing it the first time then I will suggest that you hire someone to do it for you. As, you can gather knowledge about it and then do it later by yourself.
I agree with admin. Its not like that you can't do it by yourself but its for your own good the first impression is the best impression. Outreaching other bloggers and site owners is an art so you might step aside and see how its done when some professional do it for you.
