A link attribute that tells search engines not to pass ranking signals through this link.
The nofollow attribute is a small piece of HTML (rel="nofollow") added to anchor tags to instruct search engines not to pass link equity or ranking signals to the destination page. Introduced by Google in 2005 to combat comment spam, nofollow is now part of a broader set of link attributes including rel="sponsored" for paid placements and rel="ugc" for user-generated content. A nofollow link still drives referral traffic and counts as a brand mention, but it no longer transfers the SEO authority that a dofollow link would.
