Beyond the attribute: what nofollow actually signals
Nofollow is a value of the rel attribute you add to an <a> tag: <a href="..." rel="nofollow">. Google introduced it in 2005 to fight comment spam (Google blog, 2005), giving site owners a way to link to a URL without vouching for it. The dictionary stops there. The operational reality is more interesting: nofollow has never blocked Google from seeing or crawling the URL, it only told the engine not to pass ranking credit along that edge of the link graph.
That distinction is where most confusion starts. A nofollow link can still be discovered, still be crawled through other paths, and still drive real referral traffic. What it was designed to withhold is the authority signal, the thing SEOs loosely call link juice. Understanding nofollow as an instruction about signal flow, not about visibility or indexing, fixes half the misconceptions in one move.
Here is a short visual primer before we get into the mechanics:
The counterpart is a standard follow link that does pass authority, which is what every backlink campaign is ultimately built around. Nofollow is the brake, follow is the accelerator, and a credible profile uses both.
The hint model and the rel family in 2026
The big shift came in September 2019, when Google announced two new values, rel="sponsored" for paid or affiliate links and rel="ugc" for user-generated content, and stated that as of March 1, 2020 all three (nofollow, sponsored, ugc) would be treated as hints for ranking and indexing rather than strict directives (Google Search Central, 2019). That is the single most underweighted fact in the whole topic. Nofollow no longer guarantees that no signal passes: Google decides.
This expert breakdown covers the practical line between the two link types:
In 2026 the operator question is which value to use, not whether to nofollow at all. Use sponsored on anything paid, including advertorials and affiliate links. Use ugc on forum posts, comments and profile fields. Reserve a bare nofollow for cases that are neither, like a link to a page you reference but do not endorse. Values can be combined, for example rel="sponsored nofollow", which is still valid and harmless when you want belt and braces. What you should stop doing is slapping a generic nofollow on every external link as a reflex: that throws away the granularity Google explicitly asked for.
Does the hint model mean nofollow is now a ranking factor in disguise? No. It means Google can fold a nofollow link into its understanding of the web when the surrounding context warrants it. Treat that as upside you do not control, not as a tactic you can engineer.
Where nofollow matters in a netlinking operation
For anyone running campaigns, nofollow shows up in three places that actually move the needle. First, compliance on paid placements. Google's link spam guidance is explicit that any link exchanged for money or goods must be qualified with sponsored or nofollow. If you sell or buy editorial placements and leave them as plain follow links at scale, you are building a pattern that link spam systems are trained to catch. The honest move is to label a paid placement for what it is and let the surrounding editorial context carry the value.
Second, profile naturalness. A backbone of real media coverage produces a mix: some follow, some nofollow from press citations, social mentions, Wikipedia, aggregators. A profile that is uniformly follow is the easier footprint to spot. This is one reason we operate Stringer as a network of owned French media rather than a marketplace of anonymous slots: when the linking page is a real publication with traffic, the follow or nofollow question becomes secondary to editorial fit. You can see the same logic in the catalogue of media you can browse without an account, where each source is judged on traffic and topical relevance first.
Third, pacing. Nofollow links from high-traffic pages often arrive faster and in bursts (a viral post, a forum thread), and they count toward the overall pace at which a site acquires links. They will not pass authority the way a follow link does, but they shape the rhythm of your graph and the referral traffic that keeps a link looking alive. When you plan distribution across a spread of editorial sources over time, fold nofollow placements into the calendar deliberately rather than discarding them.
Auditing nofollow across a site
Checking a single link is trivial: open developer tools, inspect the <a> element, and read the rel value. Browser extensions that highlight nofollow links on a page do the same at a glance. The real work is auditing nofollow at scale, both inbound and internal.
For your own site, run a crawler like Screaming Frog or Sitebliss and segment internal links by rel. Internal nofollow is almost always a mistake left over from old PageRank sculpting advice that Google deprecated years ago. Today an internal nofollow does not redirect equity to other pages, it simply evaporates it: the link still consumes crawl attention but passes nothing. Find them, and unless there is a deliberate reason, remove the attribute. Here is how the attribute is applied at the CMS level, useful when you are documenting fixes for an editorial team:
For inbound links, tools like Ahrefs and Semrush report the follow versus nofollow split of a backlink profile. Do not chase a target ratio: there is no published figure and anyone quoting one is guessing. Use the split as a sanity check. If a brand-new domain shows a profile that is overwhelmingly follow from low-traffic sources, that is the anomaly worth investigating, not the presence of nofollow links.
Myths that still cost rankings
The most stubborn myth is that nofollow links are worthless. They do not pass authority by default, but they drive referral traffic, build brand presence, appear in the link graph, and since 2020 may be counted at Google's discretion. A nofollow citation from a national newspaper is worth far more to a real business than a follow link from a recycled PBN. Judge the page, not the attribute.
The second myth confuses nofollow with noindex. Nofollow on a link tells Google not to pass signal; it does nothing to stop a page being indexed. If you actually want a URL kept out of the index, use a noindex meta robots tag or header on that page. Adding nofollow to every link pointing at a URL will not deindex it, because Google can reach it through other paths.
The third error, common on larger sites, is nofollowing internal links to «save crawl budget» or steer authority. That model died with PageRank sculpting. From what we see in audits, the sites that win do the opposite: clean follow internal links, a tight architecture, and nofollow reserved for genuinely untrusted outbound targets. Keep the attribute for what it was built for, controlling the signal you send to pages you do not vouch for, and stop using it as a lever it was never designed to be.
