- Nofollow links help your SEO indirectly, through referral traffic, brand searches and discovery, and Google's own documentation stops short of promising they pass ranking credit.
- Search interest in "nofollow links" sat flat for four years, rose tenfold into June 2026, then fell 76% in five weeks. The question got popular before it got answered.
- Google's current documentation never uses the word "hint". That word comes from a 2019 blog post the industry has been quoting ever since.
I have spent 50,000 hours on SEO, and the nofollow question comes back every few years wearing a different outfit. In 2026 it came back louder than ever, then vanished almost as fast.
That pattern is worth understanding before the answer, because it explains why so much advice on this topic contradicts itself. A lot of it was written in a hurry, during a spike, by people quoting a blog post from 2019.
Here is what Google and the AI companies actually publish today.
Do nofollow links help SEO?
Nofollow links help SEO indirectly, and they do not reliably pass ranking credit. The value arrives through referral traffic, brand searches, and getting your pages discovered, rather than through the link equity that a followed link carries.
That distinction matters commercially. A nofollow link from a masthead your customers actually read sends you buyers. A followed link from a site nobody visits sends you nothing except a number in a backlink tool.
Google's position is more cautious than most SEO blogs suggest, and the exact wording has moved since 2019.
What is a nofollow link?
A nofollow link is a link carrying the rel="nofollow" attribute, which tells search engines the linking site does not vouch for the destination. In the page's HTML it looks like <a href="https://example.com" rel="nofollow">.
Google introduced it to fight comment spam. If a link could not pass ranking credit, there was no point spamming forums and blog comments to get one.
Many large publishers now apply it broadly, often as a content management system default rather than an editorial judgement about your business. The attribute frequently says more about the platform than about the placement.
That default behaviour is part of why the question resurfaced so sharply in 2026.
Why did everyone suddenly start asking about nofollow in 2026?
Search interest in nofollow links rose roughly tenfold between August 2025 and June 2026, then collapsed. I pulled the five-year Google Trends series for this article. The term sat flat near 10 on Google's relative index for four straight years, climbed through late 2025, peaked at 100 in the last week of June 2026, and fell to 24 by 2 August.
That is a 76% fall in five weeks. Even discarding the two most recent data points, which Google routinely revises downward, the drop holds at 58%.
Two things follow from that shape. Most nofollow content was published into the spike, written fast and optimised for a moment rather than for accuracy. And Google Trends currently shows no rising related queries, with a single top related query: "do nofollow links help seo". People wanted one question answered. They did not want a new theory.
The most reliable answer to that question sits in Google's documentation, and it has quietly changed.
Is nofollow actually still just a hint?
The word "hint" comes from a Google blog post published in September 2019, and Google's current documentation does not use it. That is the single most repeated line in nofollow content, and it is being quoted from a source that is now nearly seven years old.
Here is what the 2019 announcement said. All three link attributes became hints for ranking purposes immediately, and nofollow became a hint for crawling and indexing from 1 March 2020. Google framed hints as signals it might consider or exclude, alongside everything else it knows about a link.
Now read Google's live documentation on qualifying outbound links. It states that links marked with these attributes "will generally not be followed". It also notes that the linked pages "may be found through other means, such as sitemaps or links from other sites, and thus they may still be crawled". The word hint does not appear.
| Source | What it says | Status |
|---|---|---|
| Google blog, September 2019 | Link attributes are "hints" for ranking; nofollow becomes a hint for crawling and indexing from 1 March 2020 | Announcement, still online |
| Google Search Central docs, current | Links with these attributes "will generally not be followed"; pages may still be crawled via sitemaps or other links | Live guidance |
| Most SEO content | "Nofollow is only a hint, so Google might count it" | Quoting the 2019 post |
Those two sources are not in direct contradiction, and I would rather be accurate than manufacture a scandal. A hint Google generally declines to follow is still a hint. The problem is how the industry reports it: "only a hint" implies Google probably counts your link, where Google's current wording implies the opposite default.
Read plainly, the guidance says do not count on it. That reading also clarifies the difference between the attributes themselves.
What is the difference between follow and nofollow links?
A followed link passes ranking signals to the destination, and a nofollow link generally does not. There is no rel="dofollow" attribute in HTML. A followed link is simply a link with no rel attribute restricting it, which is the default state of every link on the web.
Google now recognises three qualifying values, and they are not interchangeable.
| Attribute | Google's stated use | When it applies to you |
|---|---|---|
rel="sponsored" | Marks links that are advertisements or paid placements | Paid guest posts, sponsored features, affiliate placements |
rel="ugc" | Recommended for user-generated content links, such as comments and forum posts | Comment sections, forums, review platforms |
rel="nofollow" | The general case, previously recommended for both of the above | Editorial links a publisher declines to vouch for, and most CMS defaults |
Getting these right matters most on links leaving your own site, where you control the markup. Digital PR placements you earn on other people's sites are marked up however that publisher's system decides, which is covered in more detail in our digital PR link building guide.
The newer question is what happens when the visitor is not a person or a Google crawler.
Do AI engines ignore nofollow?
Nobody outside these companies knows, and the honest answer is that the major AI crawlers do not document nofollow behaviour at all. I checked OpenAI's own bot documentation while writing this. It documents separate crawlers for search, for training data and for user-initiated fetches: OAI-SearchBot, GPTBot and ChatGPT-User. Every control it offers publishers runs through robots.txt. The documentation mentions rel="nofollow", or any link rel attribute, zero times.
That is a statement about documentation, not about behaviour. I have no evidence that AI crawlers ignore nofollow, and no evidence that they respect it. What exists publicly is silence, and silence is not permission to assume either answer.
Two practical consequences come out of that. Your robots.txt is the lever these companies actually document, so it deserves more of your attention than the rel attribute on your inbound links. And being named in an AI answer works differently from a ranking signal anyway, since it resembles a mention more than a vote.
If you want to know whether these crawlers can reach you at all, our free AI crawler access checker reads your robots.txt and tells you which ones you are blocking. Measuring what happens next is covered in how to measure AI search visibility.
Before any of that, you need to know what a given link actually is.
How do you check whether a link is nofollow?
You check a link by inspecting its HTML and looking for a rel attribute. Right-click the link in Chrome, choose Inspect, and read the <a> tag in the panel that opens. If you see rel="nofollow", rel="sponsored" or rel="ugc", the link is qualified. If there is no rel attribute, it is followed.
For a whole page, view the source and search for nofollow. For a whole site, a crawler tool reports the rel attribute on every outbound link it finds.
One warning worth having. Some sites apply nofollow through JavaScript after the page loads, so the raw source and the rendered page disagree. Inspecting the rendered element, rather than the source, gives you the accurate answer.
Knowing what a link is only helps if you know what to do about it.
When is a nofollow link worth chasing?
A nofollow link is worth chasing when the placement sends you customers, or puts your brand in front of the audience that buys from you. Judge it on the traffic and the readership, and treat the ranking credit as a bonus you have not been promised.
Three cases clear that bar consistently. High-traffic publications, where a nofollow mention delivers referral visits and the branded searches that follow them. Discovery, because Google's documentation states plainly that linked pages may still be crawled through other routes, so a nofollow link on a frequently crawled page still helps a new page get found. And profile realism, because in my experience a profile made entirely of followed links looks engineered.
Where I would not spend time is asking a publisher to change the attribute. Publishers commonly apply the setting site-wide through their CMS, the journalist often has no ability to change it, and the request costs you a relationship you might want later.
The better use of that energy is earning placements in the publications your customers actually read, which is a digital PR problem rather than a technical one.

Frequently asked questions
Do nofollow links help SEO in 2026?
Nofollow links help SEO in 2026 indirectly, through referral traffic, brand searches and page discovery. Google's current documentation says links carrying these attributes will generally not be followed, so treat direct ranking credit as unlikely rather than expected.
Does Google still treat nofollow as a hint?
Google described link attributes as hints in a September 2019 blog post, and its current documentation on qualifying outbound links does not use that word. The live guidance says these links will generally not be followed, which is a more cautious statement than most SEO advice reports.
Should I ask a journalist to remove nofollow from my link?
Asking a journalist to remove nofollow rarely works, because most publishers apply the attribute automatically through their content management system rather than as an editorial decision. The journalist usually has no control over the setting.
Do AI search engines like ChatGPT ignore nofollow links?
No public documentation from the major AI companies addresses nofollow. OpenAI's crawler documentation covers OAI-SearchBot, GPTBot and ChatGPT-User entirely through robots.txt and does not mention link rel attributes. Treat any confident claim in either direction as unsupported.
Is a nofollow link better than no link at all?
Yes, when the masthead carrying it has readers who buy from you. That placement delivers referral traffic and brand awareness, where a followed link on a page nobody visits delivers neither. Judge the audience before the attribute.
