Relation Between Content and Backlinks :
Content is the King!!
Well yes content was the most important aspect for online blogging success, it is and it will be always.
But a king is nothing without his army, in the same manner content is nothing without backlinks.
If content is your talent then Backlinks gives exposure to your talent, thus gives fame. Without backlinks your content will be undiscovered, then no mattter how quality it is, your efforts will be in vain.
Unique content is a king but backlinks are Pioneers of your blogging empire.
