Nofollow

The Nofollow attribute, which can be added to a link tag (a href), tells search engine robots not to consider the link as an endorsement that would enhance the target web page's page rank. Technically speaking, the attribute tells the search engine not to follow the link at all, but that is just a recommendation and many prominent SEO experts conclude that search engines can and do follow 'nofollow' links. Example of a nofollow link: <a href="https://www.example.com/example" rel="nofollow">Read more</a>.
