Do Nofollow Links Help SEO? What They Actually Do

Ask ten marketers whether nofollow links help SEO and you’ll get ten different answers, most of them wrong in one direction or the other. Some swear nofollow links are worthless. Others treat every backlink as gold regardless of the tag. The truth sits in between, and it changed more recently than most people realize.

Here’s the short version: nofollow links don’t pass ranking power the way a standard link does, but they still influence your SEO in ways that matter. Dismissing them is a mistake. Here’s exactly what they do, what they don’t, and how to think about them in 2026.

What a nofollow link actually is

A nofollow link is a normal hyperlink with one extra instruction baked into its code. In the HTML, it looks like this:

<a href="https://yoursite.com" rel="nofollow">anchor text</a>

That rel="nofollow" attribute is a message to search engines. Google introduced it back in January 2005, alongside Yahoo and MSN, for a single reason: blog comment spam was out of control. Spammers were dropping links in comment sections to inflate their rankings, and nofollow gave site owners a way to say, “I’m publishing this link, but I’m not vouching for it.”

By default, a regular link (often called a “dofollow” link, though that attribute doesn’t technically exist) passes what SEOs call link equity or PageRank. A nofollow link, in theory, does not.

The 2019 change most people missed

Here’s where old advice goes stale. For nearly fifteen years, Google treated nofollow as a strict directive: see the tag, ignore the link, full stop.

That changed in September 2019. Google announced two things. First, it added two new link attributes to sit alongside nofollow:

Second, and more importantly, Google reclassified nofollow from a directive to a hint. As of March 1, 2020, Google reserves the right to use nofollow links for crawling and indexing, and potentially as a ranking signal, if its systems decide the link is meaningful.

In plain terms: Google no longer promises to completely ignore your nofollow links. It might follow some of them. It might factor a few into how it understands your site. You no longer have precise control, and that quietly made nofollow links more valuable than the old rules suggested.

So do nofollow links help rankings?

Directly and reliably? No. You should never build a link strategy assuming nofollow links will pass ranking power on demand. If your entire backlink plan depends on nofollow links lifting you up the results page, you’ll be disappointed.

Indirectly? Absolutely, and this is the part beginners overlook. A nofollow link from the right place helps your SEO through several side doors that have nothing to do with PageRank.

Referral traffic. A nofollow link on a busy page still sends real visitors to your site. Those visitors read your content, share it, and sometimes link to it themselves from their own sites, often with a standard followed link. That second link is the one that moves rankings, and the nofollow link is what set it in motion.

Brand visibility and search demand. When people repeatedly see your brand mentioned across the web, more of them search for you by name. Branded search volume is a signal Google reads as a sign of a real, trusted business.

A natural link profile. Real websites earn a messy mix of followed and nofollow links. A site with 100% followed backlinks looks engineered, because no legitimate site earns links that cleanly. Nofollow links are part of what makes your profile look earned rather than manufactured.

Discovery and indexing. Because Google may now crawl through nofollow links, they can help search engines find new pages on your site faster.

Do nofollow links do this? A quick reference

Are nofollow links good, then?

Yes, when they come from the right sources and sit inside a balanced profile. A nofollow link from a high-authority, high-traffic site is worth far more than a followed link from a spammy directory nobody visits.

Consider where the most powerful nofollow links tend to live. Wikipedia nofollows all its external links, yet a citation there drives serious referral traffic and signals credibility. Forbes, Business Insider, and many major news outlets nofollow contributor links. Reddit, Quora, YouTube descriptions, and most social platforms nofollow their links too. Almost nobody would turn down a mention on those platforms because the link happens to be nofollow, and they’d be right not to.

The quality of the source matters more than the tag. A nofollow mention on TechCrunch will do more for your business than a followed link buried on a forgotten page with no readers.

The follow-to-nofollow ratio myth

You’ll see people online obsessing over the “ideal” ratio of followed to nofollow links, quoting numbers like 70/30. Ignore this. There is no magic ratio Google is checking against, and chasing one is a waste of effort.

What Google actually wants to see is a profile that looks like it was earned by a real business doing real things: some editorial links, some brand mentions, some social, some directory listings, a natural share of nofollow. Focus on earning genuine coverage, and a healthy mix takes care of itself.

How to check if a link is nofollow

You don’t need paid tools to spot one. Right-click any link, choose “Inspect,” and look at the code. If you see rel="nofollow", rel="sponsored", or rel="ugc", it won’t pass standard link equity. For checking your whole backlink profile at once, tools like Ahrefs, Semrush, and Moz label every link’s attribute automatically, so you can see your follow/nofollow split in seconds.

The bottom line

Do nofollow links help SEO? Not in the direct, PageRank-passing way that a standard editorial link does, and you shouldn’t build your strategy expecting them to. But they are far from worthless. They drive referral traffic, build the brand awareness that fuels branded search, keep your link profile looking natural, and help your pages get found, and since 2020 Google may even use some of them as a ranking hint.

The smart move isn’t to seek out nofollow links or avoid them. It’s to pursue mentions on relevant, trusted, high-traffic sites and stop worrying about the tag. Earn coverage where your audience actually is, and both the followed and nofollow links will follow.
