what is use of No-follow attribute?

what do you think, by spending so much time on our site the crawlers indexed our site fully after using no-follow attribute to other outgoing link.

 

Hi,
I think no-follow is not mush value as do-follow site have.but as traffic prospect this no-follow site are best way to use this sites.

 

Basically NoFollow link attribute (rel=”nofollow”) created to stop the search engines visitor(crawler) from hyperlink

 

"Nofollow" provides a way for webmasters to tell search engines "Don't follow links on this page" or "Don't follow this specific link."

 

nofollow links wil not get the page rank Juice
