Nofollow tag is the href rel tag that gives the signal to the search engine bots to disregard specific links. Thanks to this tag, search engine bots do not distribute ranking potential between pages, even if they visit the page that has this tag. However, users can see these links and visit the relevant websites. Websites use nofollow tags especially on pages they do not have complete control over or confidence about. For example, automatic nofollow tags can be used in the blog comments, forum posts, and the guestbook section. Thus, a possible link-related problem will be prevented. In addition, the nofollow tag is applicable to external and internal links as well.
