When a person uses any anchor link in their writing, search engines may follow it and consider it as a backlink or a vote for the linked website. However, there are plenty of spammers out there who make bad use of this system. Especially the comment spammers post irrelevant comments in different niche websites and hamper the regular flow of conversation there.

There are also some other reasons (e.g. to prevent link juice flowing to the pages that are not very important from SEO perspective) why sometimes we may need to tell the search engine not to follow some of the links that can be found in a particular web page. So in plain words, we can say that links that are followed and recognized by different search engines are called DoFollow links. On the other hand, links that are not followed or recognized by the search engines are called NoFollow links.
