Nofollow Link

A nofollow link includes a `rel="nofollow"` attribute, telling search engines not to pass PageRank to the destination. Introduced in 2005 to fight comment spam, nofollow used to mean "this link doesn't count for SEO."

In 2019 Google reclassified nofollow as a hint, not a directive. Nofollow links may now influence rankings in some cases, particularly for discovery and topical relevance. They still don't pass the full equity of a dofollow link.

Common nofollow sources: Wikipedia, most Reddit links, YouTube comments, paid press releases. Common dofollow sources: editorial content, guest posts on most blogs, partner pages, podcast show notes.
