Dofollow vs Nofollow Links: What's the Difference?

A dofollow link is a standard hyperlink with no special attribute attached, which passes ranking authority - often called "link equity" - from the linking page to the page it points to, functioning as an implicit endorsement in the eyes of search engines.

A nofollow link carries a rel="nofollow" attribute, originally meant to tell search engines not to pass ranking authority through that link and not to treat it as an editorial endorsement - commonly used on comments, forum posts, paid placements, and other links a site owner doesn't fully vouch for.

The practical effect of that distinction has shifted over time. Since 2020, Google treats nofollow as a hint rather than an absolute instruction, meaning a nofollow link can still occasionally factor into ranking and discovery even though it's not designed to pass authority the way a dofollow link does. Nofollow links still matter for reasons beyond ranking: they help a site's overall link profile look natural rather than suspiciously dofollow-heavy, and they still drive real referral traffic and brand visibility. That visibility has become more important with the rise of AI-powered search, since AI systems don't factor in the nofollow attribute at all when deciding what to cite, and the platforms that generate the most nofollow links - forums, Reddit, Wikipedia, Quora - are also among the sources AI search cites most often, which means chasing dofollow links exclusively can mean under-investing in exactly the platforms where AI search visibility is being built.
