Dofollow link: definition, HTML code and rules to follow in 2026
A dofollow link is a standard link with no nofollow, sponsored or ugc attribute, which Google follows and which can pass authority. This guide covers the code, the rel attributes and its role in SEO and AI answers.
Summary
A dofollow link is a standard hyperlink with no rel="nofollow", rel="sponsored" or rel="ugc" attribute. Google can follow it, crawl the page it points to and pass authority (PageRank) to that page. It is the default state of every link on the web.
In SEO, the dofollow link is the type of backlink that most directly helps a page rank. In AI-generated answers (AI Overviews, ChatGPT, Perplexity), its role is more indirect but still real: sites cited by AI tools have far more referring domains on average, and the brand mentions that come with these links also carry weight. Links and mentions work together.
This guide gives the exact definition, shows the code, compares the rel attributes, then explains where dofollow links fit in Google and in AI answers, with the rules to apply in 2026.
Key takeaways
- "Dofollow" is a misnomer: it is not an HTML attribute, it is the default link, with no nofollow, sponsored or ugc attribute.
- In SEO, a dofollow link can pass authority. Since 2019, Google has treated rel attributes as hints, not directives.
- In AI answers, the number of referring domains is linked to the number of ChatGPT citations (SE Ranking, study updated in 2026), and brand mentions and branded anchors are among the signals most correlated with visibility in ChatGPT, AI Mode and AI Overviews (Ahrefs, December 2025).
- In 2026, a good dofollow link is judged by the media outlet, the context and the brand it cites, not just by its presence.
What is a dofollow link in SEO?
A dofollow link is a link that search engines can follow and take into account when calculating popularity. The term is a misnomer: there is no "dofollow" attribute in HTML. A dofollow link is simply the default link, one that carries no specific attribute such as nofollow, sponsored or ugc. The word became part of SEO jargon as the opposite of "nofollow", which is a real attribute.
Here is a dofollow link:
<a href="https://www.exemple.fr/guide">internal linking guide</a>
And here is the same link with nofollow:
<a href="https://www.exemple.fr/guide" rel="nofollow">internal linking guide</a>
The only difference is the rel attribute. Writing rel="dofollow" does nothing: this value is not recognised. Google's documentation on outbound links states that standard links need no attribute to be crawled and analysed.
The term is also ambiguous outside SEO ("doFollow" is, for example, a video game command). In this article, it refers only to a link followed by search engines.
Key takeaway: a dofollow link is a link with no restrictive attribute. It is the default behaviour, so there is nothing to add to the code.
Dofollow, nofollow, sponsored, ugc: which attribute for which link?
Since 2019, Google has recognised three values to qualify an outbound link. Each one covers a specific situation.
| Link type | Code | Use according to Google | How Google treats it |
|---|---|---|---|
| Dofollow | no rel attribute | Standard editorial link | Crawled and taken into account |
| Sponsored | rel="sponsored" | Links in advertisements | Hint, generally not followed |
| UGC | rel="ugc" | User-generated content (comments, forums) | Hint, generally not followed |
| Nofollow | rel="nofollow" | When the other values do not apply and you do not want to associate your site with the linked page | Hint, generally not followed |
Values can be combined, for example rel="ugc nofollow".
This table sets out the rule. Finding the right balance between followed and unfollowed links in a backlink profile is a separate, more strategic question: it depends on the choice of media outlets and the context of each link, which sits at the heart of a link building campaign on media outlets recognised by Google.
Key takeaway: sponsored, ugc and nofollow describe the nature of a link. A link with none of these attributes is dofollow.
The role of dofollow links in Google rankings
Google uses links for two things: discovering pages and estimating their importance. A dofollow link does both. It opens a crawl path to the linked page, and it can pass on part of the source page's authority (the PageRank principle).
One thing has changed and is still not widely known. On 10 September 2019, Google announced that nofollow, sponsored and ugc would be treated as hints rather than strict directives. The change was extended to crawling and indexing from 1 March 2020. As a result, the line between dofollow and nofollow is less clear-cut than it used to be. Google decides what it takes into account.
The dofollow link is still the most direct signal. It passes authority by default, without depending on a case-by-case decision by Google. But its value depends on context:
- the authority and real traffic of the linking site;
- the topical fit between the source page and the target page;
- where the link sits in the content (a link in the body of an article carries more weight than a footer link);
- the anchor text, which should stay natural and varied.
Key takeaway: in SEO, a dofollow link passes authority by default. Its real value depends on the media outlet, the context and the anchor text.
The role of dofollow links in AI answers
Generative engines do not "follow" links the way Googlebot calculates PageRank. They cite sources they consider reliable, and a site's popularity, measured in part by its links, is one of the signals associated with these citations.
Two recent studies shed light on the subject:
- The SE Ranking study on ChatGPT citation factors (129,000 domains, published in November 2025 and updated in March 2026) shows that domains with more than 32,000 referring domains are 3.5 times more likely to be cited by ChatGPT than those with 200 or fewer. The average number of citations rises from 1.6 to 1.8 below 2,500 referring domains to 8.4 above 350,000.
- The Ahrefs study on brand visibility factors in ChatGPT, AI Mode and AI Overviews (75,000 brands, December 2025) ranks web mentions of the brand (0.709 in AI Mode) and branded anchors (0.628 in AI Mode, around 0.5 elsewhere) among the most correlated signals. The raw number of backlinks, by contrast, shows a weak correlation.
These figures are correlations, not proof of cause and effect. They point to one simple idea: what matters is not the volume of links but their context. A branded anchor is a link. A dofollow link placed in an article that cites the brand creates a backlink, a branded anchor and a mention all at once. This combination is what counts for AI tools, and it is what you should aim for rather than an isolated link.
Choosing the right media outlet therefore becomes decisive: a link published on a site that AI tools already cite supports both SEO and visibility in generative AI answers at the same time.
Key takeaway: in AI answers, the dofollow link works together with the brand mention. The most cited sites have both a large number of referring domains and a large number of mentions.
7 rules to follow for your dofollow links in 2026
- Put relevance before authority. A link from a media outlet in your industry is worth more than an off-topic link on a site with strong metrics.
- Check the real traffic of the source site. A site with no organic audience passes little value and rarely attracts AI crawlers.
- Place the link in the body of the text. A contextual link, surrounded by content about the topic, is more credible than a sidebar link.
- Pair the link with the brand name. An anchor or a sentence that names the brand supports both SEO and recognition by LLMs.
- Vary your anchors. A profile dominated by exact-match anchors on the main keyword looks artificial.
- Give every link context, without trying to manipulate. Google's spam policies define link spam as creating links mainly to manipulate rankings. The examples given are artificial schemes: excessive link exchanges, over-optimised anchors spread across articles or press releases, low-quality directories, links hidden in widgets. A link that belongs in useful content, on a media outlet in the same field, with a natural anchor, follows a different logic: it informs the reader.
- Monitor links after publication. A link can switch to nofollow, disappear or be deindexed along with its page. Regular monitoring keeps you from paying for a link that no longer exists.
Key takeaway: in 2026, a good dofollow link is relevant, contextual, tied to the brand and checked over time.
How to check whether a link is dofollow
Three methods, from the quickest to the most thorough:
- Inspect the code: right-click the link, then "Inspect". If the
<a>tag contains no nofollow, sponsored or ugc, the link is dofollow. - Meta robots tag: in the page's
<head>, a<meta name="robots" content="nofollow">tag makes every link on the page unfollowed, even without an attribute on each link. - Audit tools: a crawler or a backlink analysis tool lists the attribute of each inbound link and lets you track how it changes.
Also check that the source page is indexed in Google. A dofollow link on a page that is not indexed brings almost nothing.
Key takeaway: check the link attribute, the page's meta robots tag and its indexing status. All three conditions must be met.
There is nothing technical about a dofollow link: it is a standard link that Google follows by default and that passes authority. What has changed is how its value is judged. In 2026, a good link supports both rankings in Google and presence in AI answers, provided it is placed on a relevant media outlet and tied to the brand name. Next step: audit your current backlinks against this dual SEO and AI checklist, and identify the media outlets that LLMs already cite in your industry.
Frequently asked questions about dofollow links
How can you tell if a link is dofollow?
Right-click the link, then select "Inspect". If the <a> tag contains no rel="nofollow", rel="sponsored" or rel="ugc", the link is dofollow. For a large-scale audit, a crawler or a backlink analysis tool shows the attribute of each link. Also check the page's meta robots tag: a nofollow set at that level applies to all of its links.
Should you write rel="dofollow" in the code?
No. The "dofollow" value is not one of the attributes recognised by Google. A link with no rel attribute is already followed by default. Adding rel="dofollow" changes nothing in how the link is processed.
Does a nofollow link still have SEO value?
It can. Since 2019, Google has treated nofollow as a hint rather than a strict directive, and since 1 March 2020 this also applies to crawling and indexing. Google can therefore choose to take it into account. A nofollow link also brings traffic, awareness and brand mentions, which help visibility in AI answers.
Do dofollow links help you get cited by ChatGPT?
Indirectly, yes. The 2025 SE Ranking study shows that domains with more than 32,000 referring domains are 3.5 times more likely to be cited by ChatGPT than those with 200 or fewer. This is a correlation, not proof of cause and effect. Brand mentions also count: links and mentions reinforce each other.
