Which one is better Nofollow or Dofollow?
 

I’m doing blog commenting but all blog commenting links give me Nofollow links even forum signature also give me Nofollow, how can I get Dofollow backlinks. And please suggest me which links are beneficial Dofollow or Nofollow?

Difficult to say

Try to find dofollow blogs and/or forums.

i think do follow link are better more than no follow.

Do Follow are benficial for ranking but if we are getting only dofollow links then google can consider you are doing something wrong so no follow also necessary. With No follow links we can get traffic.

Do follow backlinks are good.

As already mentioned by everyone here, DOFOLLOW links are more better in terms of SEO and DA or PA.

However if you are not getting dofollow links, dont loose confidence try to leave a nofollow link (May be it will bring some traffic for you and some of the traffic will keep repeating, who Knows?) both side More win or Win.

Do follow backlinks are better than no follow backlinks.
