Dofollow vs nofollow links: what the difference actually means for SEO

Few topics in link building generate as much confusion as the difference between dofollow and nofollow links. People talk about nofollow links as worthless, chase dofollow links exclusively, and worry that a link they earned "doesn't count" because it carries a nofollow attribute. The reality is more nuanced and more reassuring: nofollow started as a narrow anti-spam measure, it has evolved, and a natural backlink profile has always included a healthy mix of both. This guide explains what the attributes actually do, how search engines treat them today, whether nofollow links help, and why trying to acquire only dofollow links is both unnecessary and a sign your link building isn't natural.

Where nofollow came from

The nofollow attribute was introduced in the mid-2000s to fight comment and forum spam. Spammers were flooding blog comments and forums with links purely to manipulate rankings, and nofollow gave site owners a way to say "I'm not vouching for this link" — telling search engines not to pass ranking credit through it. The point was to remove the incentive for spamming links in places where anyone could drop one. Understanding this origin matters, because it explains what nofollow was designed to do: it's a signal that the linking site isn't editorially endorsing the target, not a declaration that the link is worthless or that it will harm anyone.

What dofollow actually means

"Dofollow" isn't really an attribute — it's just the name people use for a normal link that has no nofollow attribute on it. By default, a link passes ranking signals to the page it points to; that's the entire basis of how links work as an SEO signal, as our guide to how backlinks work explains. A dofollow link is simply a standard editorial link where the linking site is, by default, passing along its endorsement. When people say they want dofollow links, they mean ordinary editorial links that pass ranking value — which is what most naturally-earned links are anyway.

What nofollow does today

Over the years, search engines have refined how they treat nofollow. Originally it was a strict directive — don't pass any credit. More recently, major engines have said they treat nofollow as a hint rather than an absolute rule, meaning they may choose to consider a nofollow link for some purposes even if they don't pass full ranking credit through it. The practical upshot: a nofollow link isn't guaranteed to pass the same ranking strength as a dofollow link, but it's no longer safe to assume it does nothing at all. Engines are sophisticated enough to understand context, and a nofollow link from a major, authoritative site still signals something.

The sponsored and ugc attributes

Search engines later introduced two more specific link attributes alongside nofollow. The sponsored attribute marks links that are paid or part of an advertising or sponsorship arrangement. The ugc attribute marks links in user-generated content — comments, forum posts, and similar. These exist so site owners can be more precise about why a link isn't a standard editorial endorsement: it's an ad, or it came from a user rather than the site's editorial team. For link building, the relevance is that paid links should carry the sponsored attribute — a paid link passed off as a standard editorial link is exactly the kind of manipulation that can get a site penalised, as our link building guide covers.

Do nofollow links help SEO?

This is the question everyone asks, and the honest answer is: often yes, in ways that matter even when direct ranking credit is uncertain. First, engines may consider nofollow links as hints, so dismissing them entirely is wrong. Second, and more importantly, nofollow links from relevant, authoritative places drive referral traffic, build brand awareness, and get your brand and content in front of people — including places that influence AI systems and future linkers. A nofollow mention in a major publication is enormously valuable regardless of the attribute, because of the audience, the credibility, and the discovery it drives. Judging a link purely by whether it's dofollow misses most of what makes a link worth having.

Why a natural profile has both

Here's the part that chasing dofollow links gets backwards: a natural, healthy backlink profile always contains a mix of dofollow and nofollow links. Real websites earn links from all kinds of sources — news sites, social platforms, forums, comment sections, directories — and many of those are nofollow by default. A backlink profile that is 100% dofollow is unnatural; it's a pattern that suggests the links were deliberately acquired rather than naturally earned, which is itself a risk signal. So the mix isn't just acceptable, it's expected. Trying to filter your link building to dofollow-only makes your profile look more manipulated, not less.

Stop obsessing over the attribute

The practical takeaway is to stop treating the dofollow/nofollow distinction as the thing that determines whether a link is worth pursuing. The questions that actually matter are the ones our guide to link quality raises: is the linking site relevant and credible? Will the link drive real traffic and awareness? Would you want this link even if search engines didn't exist? A relevant, authoritative, traffic-driving link is worth having whether it's dofollow or nofollow. A low-quality dofollow link from an irrelevant site is worth little and potentially harmful. The attribute is one small factor, not the headline.

How to check a link's attribute

If you do want to check whether a specific link is dofollow or nofollow, you can inspect the page's underlying code and look at the link element for a rel attribute containing nofollow, sponsored, or ugc — if none of those is present, it's a standard dofollow link. Browser extensions and SEO tools can highlight this automatically across a page. This is useful for understanding your profile or evaluating a link opportunity, but keep it in perspective: knowing the attribute tells you one thing about a link, and it's rarely the most important thing. Use it as a data point alongside relevance, authority, and traffic potential, not as a pass/fail test.

The bottom line

Dofollow is just a normal link that passes ranking signals; nofollow is an attribute, born from anti-spam efforts, saying the linking site isn't editorially vouching for the target. Engines now treat nofollow as a hint rather than an absolute rule, and nofollow links still drive traffic, awareness, and discovery that matter enormously. A natural backlink profile contains both, and an all-dofollow profile looks manipulated. So stop chasing the attribute and start judging links the way that actually predicts value: relevance, authority, and whether the link would be worth having even if it passed no ranking credit at all. Get that right and the dofollow/nofollow mix takes care of itself.

Frequently asked questions

What's the difference between a dofollow and nofollow link?

A dofollow link is a normal link with no special attribute — by default it passes ranking signals to the page it points to. A nofollow link carries a rel="nofollow" attribute telling search engines the linking site isn't editorially vouching for the target, so it traditionally passes little or no direct ranking credit. Dofollow isn't actually an attribute you add; it's just the name for a standard link without nofollow on it.

Do nofollow links help SEO?

Often yes, in ways that matter. Search engines now treat nofollow as a hint rather than an absolute rule, so they may still consider these links. More importantly, nofollow links from relevant, authoritative places drive referral traffic, build brand awareness, and get your content discovered — all of which have real value regardless of whether direct ranking credit passes. Dismissing a link purely because it's nofollow misses most of what makes a link worth having.

Should I only build dofollow links?

No — and trying to is counterproductive. A natural backlink profile always contains a mix of dofollow and nofollow links, because real sites earn links from news, social platforms, forums, and comments, many of which are nofollow by default. A profile that's 100% dofollow looks deliberately acquired rather than naturally earned, which is itself a risk signal. The mix isn't just acceptable, it's expected and healthy.

What are the sponsored and ugc link attributes?

They're more specific link attributes introduced alongside nofollow. The sponsored attribute marks paid or advertising links; the ugc attribute marks links in user-generated content like comments and forum posts. They let site owners be precise about why a link isn't a standard editorial endorsement. For link building, the key point is that paid links should carry the sponsored attribute — disguising a paid link as a standard editorial one is a form of manipulation that can get a site penalised.

How do I tell if a link is dofollow or nofollow?

Inspect the page's underlying code and look at the link element for a rel attribute containing nofollow, sponsored, or ugc — if none of those is present, it's a standard dofollow link. SEO browser extensions and tools can highlight this automatically across a page. It's useful for understanding your profile, but keep it in perspective: the attribute is one small data point, and relevance, authority, and traffic potential matter far more than whether a given link is dofollow.
