Nofollow links don't reliably pass PageRank — but Google treats them as hints, so some signals may transfer
A nofollow mention in a high-traffic publication can drive more value than a dofollow link from a low-traffic site

How Nofollow Link Works
Nofollow links were introduced by Google in 2005 as a way for publishers to link to content without endorsing it for ranking purposes. The rel="nofollow" attribute tells crawlers not to pass PageRank through the link. Common sources of nofollow links include Wikipedia, most news sites (for external links), social media platforms, blog comments, forum posts, and press release distribution services.
Why Nofollow Link Matters for B2B Marketing
In 2019, Google updated its nofollow policy, reclassifying nofollow as a "hint" rather than a strict directive. This means Google may choose to follow nofollow links and consider them in certain contexts, though authority transfer is not guaranteed. In practice, nofollow links remain significantly less valuable than dofollow for direct ranking improvements.
Nofollow Link: Best Practices & Strategic Application
Despite limited direct SEO value, nofollow links serve important strategic purposes: they drive referral traffic from high-traffic platforms, build brand awareness and social proof, contribute to a natural-looking mixed link profile, and can indirectly boost rankings by increasing branded search volume and engagement signals.
Agency Perspective: Nofollow Link in Practice
Agency perspective: Avoid over-indexing on the nofollow/dofollow distinction when evaluating digital PR results. A nofollow mention in Forbes or the Wall Street Journal carries enormous brand authority, generates thousands of referral visitors, and often leads to secondary dofollow links as other publishers cite the same story. Measure link campaigns by traffic, brand lift, and lead quality — not just follow status.
Frequently Asked Questions: Nofollow Link
A nofollow link contains the rel="nofollow" HTML attribute, which instructs search engines not to pass ranking authority through the link. Introduced by Google in 2005 to combat comment spam, nofollow links have limited direct SEO value but still drive traffic and brand signals.
Directly, nofollow links have limited SEO value since they don't reliably pass ranking authority. Indirectly, they can boost SEO by driving traffic that increases engagement signals, generating branded search volume, building brand credibility that leads to additional dofollow links, and contributing to a natural-looking link profile that avoids penalties.
Wikipedia applies nofollow to all external links. Most major news sites (Forbes, Business Insider, TechCrunch) nofollow external links. Social media platforms (Twitter/X, LinkedIn, Facebook, Instagram) nofollow all links. Press release distribution services (PRWeb, PR Newswire) typically nofollow links in distributed releases.
Use nofollow for paid/sponsored links (required by Google guidelines), user-generated content where you can't vet the linked sites, affiliate links (or use rel="sponsored"), and links to pages you don't want to endorse. For standard editorial outbound links to reputable sources, dofollow is appropriate and beneficial for user trust.
