Dofollow vs Nofollow Backlinks: What Actually Passes Value in 2026

The dofollow/nofollow distinction is one of the oldest ideas in SEO and one of the most out of date. Google changed how it treats these attributes in 2019, and most advice still describes the pre-2019 behaviour.

Here is how link attributes actually work now, and what it means for the links you pursue.

First, a Correction: "Dofollow" Is Not Real

There is no rel="dofollow" attribute. It has never existed in any specification. A followed link is simply a link with no rel attribute restricting it — the default state of every link on the web.

The term persists as convenient shorthand, and that is fine. But if a provider's reporting shows rel="dofollow" in the markup, someone has added a meaningless attribute, which tells you something about their technical understanding.

The Four Attributes That Exist

No rel attribute — a normal link. Passes ranking value. This is what you are acquiring.

rel="nofollow" — introduced in 2005 to combat comment spam. Originally a strict directive to ignore the link entirely.

rel="sponsored" — introduced 2019, for paid or advertising links.

rel="ugc" — introduced 2019, for user-generated content such as comments and forum posts.

Attributes can be combined, and rel="nofollow sponsored" is common on advertising links.

The 2019 Change: Directives Became Hints

This is the part most guides missed. In March 2020 Google began treating all three attributes as hints rather than strict directives — meaning Google may choose to consider a nofollowed link for ranking purposes if it judges the link meaningful.

Google's stated reasoning was that publishers had begun applying nofollow so broadly — Wikipedia, major news outlets, most large platforms — that treating it as an absolute instruction was discarding useful information about the web.

The practical consequences:

• A nofollowed link from a major publication is not necessarily worthless.
• You cannot rely on nofollow to prevent value passing — it is not a guarantee in either direction.
• Nofollowed links still very likely pass far less than followed ones on average.
• Nobody outside Google knows the actual weighting, and anyone claiming a percentage is guessing.

Why an All-Followed Profile Is a Problem

Here is the counterintuitive part. A backlink profile consisting entirely of followed links is itself an unnatural pattern.

Real businesses accumulate nofollowed links constantly and unavoidably: social media profiles, Wikipedia citations, most major news sites, press release syndication, forum mentions, review platforms, job boards. A genuinely popular site will have a substantial minority of nofollowed links without ever intending to.

A profile with 100% followed links means every single link was acquired deliberately, and that is visible. Natural profiles are messy. This is one of several reasons a uniform link profile is a risk factor even when each individual placement is defensible — a theme covered in types of backlinks.

The Secondary Value of Nofollowed Links

Even setting ranking value aside, nofollowed links do real work.

Referral traffic. A nofollowed link on a well-read page sends actual visitors, and visitors can become customers. The attribute has no effect on this whatsoever.

Brand signals. Mentions across the web appear to contribute to how Google understands your entity, independently of link equity.

Discovery. Google still crawls nofollowed links, so they help pages get found.

Secondary linking. A nofollowed link on a high-traffic page frequently leads to followed links from people who found you through it. This is how digital PR campaigns compound — see digital PR.

How to Check an Attribute

View the page source and find your link. Look at the rel value on the anchor tag. Browser extensions that highlight nofollowed links work too, though they occasionally misreport JavaScript-rendered links.

Do this on every paid placement. Some providers deliver nofollowed links without mentioning it, and since the attribute is invisible on the rendered page, nobody notices unless they check. We verify the attribute after every placement — it is part of what the reporting on niche edits and backlink services confirms.

Should You Pursue Nofollowed Links Deliberately?

Not as a target, but do not decline them either.

If a major publication in your industry will cover you with a nofollowed link, take it — the referral traffic, brand signal and secondary linking are worth more than the attribute costs you. If someone is selling you nofollowed links as though they were followed, that is a different matter entirely.

The practical rule: pursue links you would want if attributes did not exist. Relevance, traffic and editorial legitimacy determine value far more than rel does, as covered in SEO backlinks.

The Summary

Followed links are what you are buying and what you should expect. Nofollowed links are not worthless and a profile without any is unnatural. Always verify the attribute on paid placements, because the failure is invisible otherwise.

And ignore anyone quoting a precise percentage of value that nofollow passes. Nobody outside Google knows, and the honest answer is that it varies by context.
