A publisher emails you back about the guest post.
Good news: they’ll publish your article. Bad news: “our outbound links are all nofollow.”
So you pass. No dofollow, no deal.
That decision just cost you a link from a DR 80 publication.
Here’s the thing most SEOs still get wrong in 2026: the dofollow vs nofollow line isn’t what it was five years ago. Google changed how it treats these links in 2019. AI search doesn’t care about the difference at all. And the 2024 Google API leak plus 2026 ranking data confirmed what experienced practitioners already suspected — nofollow isn’t the dead end it used to be.
By the end of this guide, you’ll know:
- Exactly what dofollow and nofollow links are (and what they look like in HTML)
- How Google’s 2019 hint model changed the game
- The rel=”sponsored” and rel=”ugc” attributes you probably aren’t using properly
- Whether nofollow links still help your SEO (spoiler: yes, more than you think)
- Why AI search has flipped the nofollow conversation entirely
- When to accept a nofollow link — and when to walk away
Let’s clear this up once and for all.
Dofollow vs Nofollow: The Simple Version
Every link on the web falls into one of two buckets.
Dofollow links are the default. No special attribute. They pass PageRank (“link equity”) from the linking page to the destination. This is what every SEO historically chased.
Nofollow links carry the rel=”nofollow” attribute in the HTML. Traditionally, Google was told to ignore these links for ranking. Since 2019, that’s changed — more on this below.
Here’s what each looks like in actual HTML:
<a href=”https://example.com”>This is a dofollow link</a>
<a href=”https://example.com” rel=”nofollow”>This is a nofollow link</a>
Same href. Same anchor text. Different signal to search engines.
If you’re still shaky on the basics of how links pass authority in the first place, our what are backlinks primer covers the mechanics before we go deeper here.
How Dofollow and Nofollow Actually Work
Think of links as votes.
When Site A links to Site B with a dofollow link, it’s telling Google: “I vouch for this page. Give it some of my credibility.”
When Site A adds rel=”nofollow”, it’s saying: “I’m linking here, but I’m not endorsing this page. Don’t pass any of my authority along.”
Simple idea. Messy implementation. Let’s walk through the history.
Where nofollow came from (2005)
Back in 2005, comment spam was destroying the web.
Someone would post a spam comment on your blog with a link to their casino / pharmacy / dodgy affiliate site. Search engines treated it as a real endorsement. Spammers rocketed up the rankings. Legitimate sites got buried.
Google, Yahoo, and Microsoft got together and created the rel=”nofollow” attribute as a fix. Blog owners could mark comment links nofollow. Spammers lost their incentive.
For 14 years, nofollow worked exactly as described: Google saw it, Google ignored the link completely for ranking purposes.
Then September 2019 happened.
The 2019 Change: Nofollow Became a “Hint”
This is the single most important thing in this entire guide.
On September 10, 2019, Google announced on its official Search Central blog that nofollow was changing. From that date onwards, nofollow would be treated as a hint, not a directive.
Translation: Google could now choose to follow and count a nofollow link for ranking purposes if its algorithms decided the link was genuinely relevant and trustworthy.
Danny Sullivan (Google’s Search Liaison) clarified this point publicly: “Nofollow became a hint for ranking purposes.” It’s not that Google promised to start counting nofollow links — it’s that Google reserved the right to when the link looks legitimate.
Why Google made this change · Google’s algorithms had grown sophisticated enough to judge link quality themselves. Treating every single nofollow link as worthless was throwing away useful data — especially data from Wikipedia, Reddit, news sites, and huge authoritative publishers who nofollow everything by default.
The 2020 addition: sponsored and UGC attributes
Alongside the nofollow update, Google rolled out two new attributes:
- rel=”sponsored” — for paid links, affiliate links, advertisements, and any link involving financial compensation.
- rel=”ugc” — for user-generated content like blog comments, forum posts, Reddit threads, and community platforms.
Both are also treated as hints. You can combine them with nofollow, use them alone, or let publishers pick what fits. The practical upshot: Google now has four different link attributes to work with instead of the old binary.
Here’s the full reference:
| Attribute | What it signals | When to use it |
| (none / dofollow) | Full editorial endorsement; pass PageRank | Genuine citations, trusted references, your own content |
| rel=”nofollow” | No endorsement; hint to Google not to pass authority | Untrusted sources, when you can’t vouch for the destination |
| rel=”sponsored” | Paid relationship; do not treat as editorial vote | Affiliate links, paid placements, advertisements |
| rel=”ugc” | User-generated; site didn’t place the link editorially | Blog comments, forum posts, community platforms |
Google’s current official guidance on qualifying outbound links confirms: “All the link attributes — sponsored, UGC and nofollow — are treated as hints about which links to consider or exclude within Search.”
Hints. Not absolutes.
Do Nofollow Links Still Help SEO? (The 2026 Answer)
Yes.
Not in every case. Not as much as dofollow links from similar-quality sources. But the idea that nofollow = worthless is outdated and is costing a lot of SEOs real opportunities.
Here’s the 2026 evidence:
1. Google may pass value through them
The hint model means some nofollow links actively influence rankings. Google won’t tell you which ones. But the signal isn’t zero anymore.
Joy Hawkins at Sterling Sky ran a controlled test placing a nofollow link on a high-visibility forum. Measurable ranking improvements for the target page appeared within 24–48 hours. That wouldn’t have happened under the pre-2019 model.
2. They drive referral traffic
This has always been true, but it’s worth emphasising.
A nofollow link from The New York Times, The Guardian, or TechCrunch still drives real humans to your site. Those humans convert, engage, share, and sometimes link to you from their own dofollow sites. The ranking bonus isn’t direct — but it’s real.
3. They make your link profile look natural
A backlink profile with only dofollow links is a giant red flag. Real websites earn a mix — blog comments, forum mentions, social posts, Wikipedia citations, Reddit threads, news comments, all of which tend to be nofollow or UGC by default.
If every link pointing to your site is dofollow and keyword-rich, Google’s spam classifiers notice. 100% dofollow profiles look manipulated because they usually are. A healthy ratio includes plenty of nofollow signal.
4. They build brand visibility and E-E-A-T
Google’s E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) evaluation pulls from signals across the web. Nofollow mentions of your brand on authoritative sites contribute to the trust signal even when they don’t pass link juice directly.
This overlaps with the unlinked brand mentions playbook — brand mentions convert to links, but even when they don’t, they still register as credibility signals.
The AI Search Twist (This Is Huge)
Here’s the biggest 2026 development, and one most SEO guides are still missing.
AI search doesn’t care about nofollow at all.
ChatGPT, Perplexity, Google AI Overviews, Gemini, Claude — none of them respect the nofollow attribute. When they retrieve content to cite in generated answers, they evaluate source relevance, authority, and content quality. They don’t look at HTML link attributes.
This matters enormously. Here’s why:
- Reddit is Perplexity’s #1 citation source at 46.7% of all citations (Averi AI data, 2026). Virtually every external link on Reddit is rel=”ugc” nofollow.
- Wikipedia citations are nofollow by default — yet Wikipedia references are among the most commonly surfaced sources across all major AI systems.
- Forum discussions and news comments are nofollow UGC — and they’re showing up in AI Overviews and ChatGPT responses constantly.
If you’re optimising only for dofollow Google authority in 2026, you’re underinvesting in the community presence that drives AI recommendation visibility.
The practical implication · A nofollow Reddit mention from a thread with high engagement might generate more commercial value in 2026 than a dofollow link from a DR 40 guest post farm. That’s a sentence that would have sounded crazy in 2018. It’s common sense now.
This doesn’t mean dofollow links stopped mattering. It means the binary “dofollow = valuable, nofollow = worthless” framework is broken for modern SEO.
The balanced profile insight
Here’s where the 2026 data gets genuinely interesting.
Ahrefs’ AI brand visibility research found a stronger correlation between community platform mentions (overwhelmingly nofollow UGC) and AI citation rates than between traditional dofollow backlinks and AI citation rates.
Not a small gap. A substantial one.
Think about what that means. Every SaaS brand pouring outreach budget exclusively into dofollow guest posts and niche edits is underinvesting in the exact channels — Reddit, Quora, Discord communities, industry forums, YouTube comment discussions — that drive AI recommendation visibility.
A genuine 2026 link strategy builds authority across both sides of the ledger: editorial dofollow placements for traditional ranking, community nofollow presence for AI visibility. The brands winning both search channels simultaneously are the ones who stopped treating the attribute as the deciding factor.
When Each Type of Link Matters
Different use cases, different weighting. Here’s how to think about it:
Dofollow links matter most for:
- Competitive keyword rankings where link equity is the deciding factor
- New domains trying to build authority from scratch
- Money pages — product, service, and commercial landing pages
- Topic authority building (topical PageRank flow)
- Traditional organic search visibility
Nofollow links matter most for:
- Brand visibility and recognition
- AI search citation (ChatGPT, Perplexity, AI Overviews)
- Referral traffic from high-quality sources
- Natural link profile diversity
- E-E-A-T signals across the web
- Risk management — a 100% dofollow profile looks manipulated
The real 2026 question to ask
Stop asking: “Is this link dofollow or nofollow?”
Start asking: “Is this a link I’d be proud of, from a site my target customers actually read?” If yes, take it — whatever the attribute.
A nofollow from The Guardian beats a dofollow from a random DR 15 blog, every single time. The outreach guide covers how to evaluate link opportunities based on real quality signals instead of just attribute type.
How to Check If a Link Is Dofollow or Nofollow
Three easy methods, fastest to most thorough:
Method 1: Right-click → Inspect
Right-click any link in your browser. Choose “Inspect” (or “Inspect Element”). The HTML panel opens showing the exact markup.
Look for the <a> tag containing your link. If it has rel=”nofollow”, rel=”sponsored”, or rel=”ugc” — now you know. If the rel attribute is missing entirely, it’s a dofollow link.
Works on desktop browsers. Takes about 5 seconds per link. Free.
Method 2: Browser extensions
Several free extensions highlight nofollow links on any page:
- NoFollow (Chrome/Firefox) — adds red borders around nofollow links
- SEOquake — full SEO overlay including link attributes
- MozBar — shows link attributes plus DA/PA data on hover
Install once. See attribute data on every page you browse.
Method 3: Backlink tools
For scale — when you need to check 500 links at once — you want best link building tools in 2026. Ahrefs, Semrush, Moz Link Explorer, and Majestic all surface link attributes in their backlink reports with filters for dofollow-only or nofollow-only views. This is the right approach for any proper backlink audit workflow.
Should You Nofollow Your Internal Links?
Almost never.
For years, SEOs used a tactic called “PageRank sculpting” — nofollowing links to low-value internal pages (login, cart, privacy policy) in the hope of redirecting that PageRank to important pages.
Google killed this in 2009.
Matt Cutts announced the change: PageRank assigned to nofollowed internal links evaporates. It doesn’t redistribute to your dofollow links. It just vanishes. If your page has 10 links and you nofollow 5, the remaining 5 get nothing extra.
I still see sites in 2026 nofollowing their utility links thinking they’re sculpting PageRank. They’re not. They’re just wasting it.
What actually works · If you want to concentrate authority, reduce the number of links on your important pages. Fewer total outbound links means each remaining link passes more juice. Don’t nofollow — just remove.
Exceptions where internal nofollow makes sense:
- User-generated content you can’t moderate — use rel=”ugc”.
- Affiliate links on review pages — use rel=”sponsored”.
- Links to pages you specifically don’t want indexed — though noindex in the destination’s meta is usually cleaner.
5 Common Dofollow/Nofollow Mistakes That Cost You
1. Refusing nofollow links from big publishers
Still the most expensive mistake in link building. Walking away from a Forbes or BBC nofollow mention because “it doesn’t help SEO” is leaving real value — traffic, brand, E-E-A-T, AI citations — on the table.
2. Building 100% dofollow link profiles
If every single referring domain pointing to you is a dofollow editorial placement, Google’s spam classifiers flag it as unnatural. Real link profiles include a mix. When planning your outreach via the 15 link building strategies that work in 2026, make sure your tactical mix naturally produces both types.
3. Using rel=”nofollow” for paid links
Technically still works, but rel=”sponsored” is the correct attribute for paid relationships. Using nofollow alone for ads risks being interpreted as trying to mask the commercial relationship. Be explicit. This matters more for niche edits guide buyers than anyone else.
4. Forgetting about UGC attributes
If you run a blog with comments, a forum, or any user contribution, your comment links should carry rel=”ugc”. Most WordPress plugins set this automatically now. Check that yours does.
5. Obsessing over attribute type instead of source quality
A dofollow link from a junk site is worse than useless — it can actively drag your profile down as Google’s spam systems evaluate it. A nofollow link from a major industry publication is a win. The attribute matters less than the source. Every single time.
Dofollow vs Nofollow FAQ
Are dofollow links better than nofollow links?
In traditional Google SEO, yes — they directly pass PageRank. But “better” depends on the goal. A nofollow link from a high-authority, high-traffic site can produce more commercial value than a dofollow link from a low-quality source, especially in 2026 when AI search citations don’t distinguish between them.
How do I make a link nofollow?
Add rel=”nofollow” to the HTML anchor tag. For example: <a href=”https://example.com” rel=”nofollow”>text</a>. In WordPress, most SEO plugins (Rank Math, Yoast, SEOPress) add a nofollow checkbox to the link editor. If you’re linking to a paid placement, use rel=”sponsored” instead.
Does Google count nofollow links?
Sometimes. Since September 2019, Google treats nofollow as a hint rather than a directive. Google’s algorithms may choose to count a nofollow link for ranking purposes if the link looks genuinely relevant and trustworthy. You can’t force this, and you can’t reliably predict it — but the signal isn’t zero the way it was pre-2019.
What ratio of dofollow to nofollow should I aim for?
There’s no magic ratio. A natural profile is somewhere in the range of 60–80% dofollow to 20–40% nofollow, but the exact split depends heavily on your niche, your tactics, and your brand presence. Chasing a specific ratio is the wrong goal — focus on earning quality links from varied sources and the ratio sorts itself out.
Do social media links count as dofollow or nofollow?
Almost all social platform links are nofollow or UGC. Twitter/X, LinkedIn, Facebook, Instagram, TikTok, YouTube — all nofollow by default. They still drive real traffic and brand signal, they just don’t pass PageRank directly. Social shares correlate with ranking but aren’t a direct ranking factor.
Are Wikipedia links nofollow?
Yes, Wikipedia uses nofollow on all outbound external links. But Wikipedia citations are among the most valuable links you can earn — they drive significant referral traffic, act as strong E-E-A-T signals, and are one of the most frequent citation sources in AI search. Worth chasing, nofollow and all.
How do I know if my backlinks are dofollow or nofollow?
Run a backlink audit using Ahrefs, Semrush, or Moz. Their backlink reports filter by link attribute. For small link profiles you can spot-check manually with a browser extension. For anything with more than 50 referring domains, a proper tool is the only sensible approach.
Should I only pursue dofollow links in outreach?
No. Walk into every outreach campaign — whether it’s digital PR guide, HARO guide, guest posting guide, broken link building, Skyscraper Technique guide, or resource page link building — prepared to accept quality nofollow placements. Some of the best opportunities in 2026 are nofollow by policy, and refusing them over the attribute is a pure self-own.
The Bottom Line
The dofollow vs nofollow distinction mattered more in 2018 than it does in 2026.
Here’s what to actually remember:
- Dofollow links pass PageRank directly. Nofollow links don’t — usually.
- Google’s 2019 hint model means nofollow is no longer a hard zero.
- AI search doesn’t distinguish between the two at all.
- Quality of source matters more than attribute type.
- A 100% dofollow profile is a red flag, not a flex.
Chase quality links. Let the attribute sort itself out.
Everything else in this industry — the What Is Link Building? fundamentals, the tactical 15 link building strategies that work in 2026, the anchor text guide work — is about building the kind of link profile that ranks, converts, and holds up against future algorithm updates. Nofollow vs dofollow is just one filter in that process. Don’t make it the whole strategy.
Go get the link.
