Hi,

I think there is a 20/80 rule that applies here too where 20% share is of the quality and great content while the rest is in how well you promote it.

We've been doing that too and saw good share on our personal blog at Omnicore.

One more tip that I can give is to bring in experts as the Ego-bait posts get shared a lot.
e.g http://backlinks.com.au/link-building-strategies-2014/

If you're interested in putting the content marketing plan in action for 2014, set up a call.

Best Wishes,
Salman
