Do follow and no follow
 

what is the difference between no follow and do follow

Backlinks are of two types,
Nofollow : Backlinks that do not pass any backlinking credit. You can use nofollow attribute with backlinks which you don't trust.

Dofollow : By default, backlinks are dofollow. You will get credit for these backlinks.

Google/search engines follow do follow but i don't think no follow are of no value.

Dofollow means crawler/bot just follow that site, no follow means bot won't follow that site like.

Dofollow Baclinks:- Search engine crawlers crawl the whole content on webpage including links,keywords etc.
Nofollow Backlinks:- Nofollow backlinks are ignored by search engine crawlers.

this question is very important.
