Nofollow

The nofollow attribute is an HTML element used to instruct search engines that the hyperlink should not influence the ranking of the link’s target in the search engine’s index. Essentially, it tells search engines not to pass any link equity or authority through to the site to which it is linked. This can be useful for webmasters who want to link to a page without implying an endorsement, such as in user-generated content or sponsored links.
