A Nofollow link is an HTML attribute that tells search engines not to follow the link to its destination. This means that search engines will not consider the linked page a factor in their rankings. An example of a Nofollow link is when a blog author links to a sponsored post on their site but wants to clarify to search engines that they are not endorsing the product. By adding the Nofollow attribute to the link, the search engine will not give the linked site any SEO credit for the link.
