Nofollow link
A nofollow link is a hyperlink with a tag that tells search engines not to pass ranking authority to the destination. It is the standard treatment for paid, sponsored and user-generated links.
Also known as:
rel=nofollow, nofollow attribute
What is nofollow link?
A nofollow link is a regular hyperlink with the HTML attribute rel="nofollow" added, which signals to search engines that the linking site does not vouch for the destination. The link still works for readers and still passes referral traffic. It just does not contribute the link-equity signal that a normal "follow" link does. Google now treats nofollow as a hint rather than a strict directive, but the practical effect on ranking remains negligible.
rel="nofollow": Use for general untrusted or unvetted links
rel="sponsored": Use specifically for paid placements and affiliate links
rel="ugc": Use for user-generated content like comments and forum posts
No rel attribute: A standard, follow link that passes full link equity
Why does nofollow link matter?
Nofollow keeps a site honest with search engines and aligns with Google's webmaster guidelines on disclosed paid links. Without it, sponsored placements and user-generated links would distort rankings, treating advertising as editorial endorsement. For content teams, the link attribute matters in two directions: when accepting paid placements, mark them properly. When earning organic links, prefer publications that pass equity rather than nofollow everything by default.
How do you use nofollow link?
Apply rel="sponsored" to every paid, affiliate or sponsored link, and apply rel="ugc" to comment and forum link sections.
Audit your site's outbound links yearly, looking for sponsored or affiliate links that slipped through without the right attribute.
When pitching for backlinks, ask whether the destination publication uses follow or nofollow links by default, since the answer affects the value of the placement.
