HELP NEEDED with idea how hard will be to rank this

Will it be hard to rank KW like this, when this is my competition? I wouldn't ask normally. But two weeks ago i built from my point of view the most optimized website so far and since third day it appeared on 2-5 th page on long tails, it is moving up, but really slowly. And still not seeing any results for the main kw. So i want to start another project, while i'll do linkbuilding.
So for new kw i found, here is the competition, first number is page authority and second domain authority. The first website has 740 backlinks and no text on homepage and wikipedia about 140 others don't.
Funny thing is, that long tail kw of this keyword has much bigger competition...


1 http://www.keyword.com 55 47
2 http://en.wikipedia.org/wiki/keyword 65 100
3 http://twitter.com/KEYWORD?lang=en 1 100
4 http://www.instagram.com/keyword 1 99
5 http://www.people.com/article/keyword 1 92
6 http://www.facebook.com/keyword 1 100
7 http://www.ew.com/article/keyword 1 91
8 http://www.cnn.com/2016/keyword 1 99


Could i rank it with 3-5k article, fully optimized with unique and seo optimized images + 1-2 unique videos embed on it?
+1 article a day linking to other page or to homepage for 30 days? (around 300-500 words)
And for backlinks i would use social + some expired tumblrs and blogspots with pa and da over 15 or 20?


Thanks for your feedback.

Seemly your keyword level is "Moderate Comp."
You can't rank them by articles only, you need to build a HQ link, PBN, guest post, and other diversification link

Ok, thanks. But what you're saying basicly is, that it should be possible to rank it in 3-6 months?

Yes you can rank for this keyword at least on the first page with the right backlinks.
