Nofollow Link
What is Nofollow Link?
In the SEO industry, a nofollow link is a type of hyperlink that has a special HTML attribute (rel='nofollow'). This attribute tells search engines like Google not to follow the link to its destination, effectively preventing the linked page from gaining any SEO value or 'link juice' from the linking site. Nofollow links are often used in situations where a website doesn't want to endorse or pass authority to another site. For example, they are commonly found in user-generated content like blog comments and forum posts, as well as in sponsored or paid links. While nofollow links don't directly contribute to a site's search engine rankings, they can still drive traffic and increase visibility when clicked by users.
