Will NoFollow Attribute Help Me To Get Higher Rank Over Search Engines?

I am working on eCommerce website. [Spider Office Chairs]

Right now, NoFollow attribute is not available on my website. I would like to define NoFollow attribute on website.

I am little bit confuse with current performance. Will NoFollow attribute help me to improve organic performance or not?

If yes so, How can I define or finalize outbound links on which I will put NoFollow attribute?

yes dofollow transfer page rank and google thinks , if sites are passing page rank it will not good for both websites so use nofollow tag

No not at all Dofollow is better than no follow attribute.
