If you have spent any time building backlinks, you have likely come across the dofollow vs nofollow debate. For years, the answer seemed simple: dofollow links move the needle, nofollow links do not. In 2026, that framing is outdated.
Google changed how it treats nofollow links back in September 2019, and the SEO industry is still catching up to what that shift actually means in practice. This guide cuts through the noise to explain what each link type does, how Google really handles them today, and what a smart link strategy looks like now.
What Is a Dofollow Link?
A dofollow link is the default state of any hyperlink on the web. When you create a standard anchor tag in HTML without any special attribute, it is automatically treated as dofollow. There is no “dofollow” tag as such; the name is simply a colloquial shorthand for a link that search engines follow and count as a ranking signal.

<a href=”https://example.com“>Anchor Text</a>
When a search engine crawler encounters a dofollow link, it follows the link to the destination page and passes a portion of the originating page’s authority, commonly called link equity or PageRank, to that destination. Think of it as a recommendation letter: the more authoritative the referring site, the more weight that recommendation typically carries.
Dofollow links are generally what SEOs mean when they talk about “building backlinks” in the context of improving search rankings. Pages that rank well in Google tend to attract links from a wider variety of referring domains, and those links are predominantly dofollow.
What Is a Nofollow Link?
A nofollow link includes an HTML attribute that signals to search engines that the linking site does not necessarily want to pass ranking credit to the destination.
html <a href=”https://example.com“ rel=”nofollow“>Anchor Text</a>
Google introduced the nofollow attribute in 2005 primarily to combat comment spam. Before its introduction, anyone could drop a link in a blog comment and gain SEO value, which led to rampant abuse. By marking user-contributed links as nofollow, site owners could allow linking without endorsing every destination.
How Dofollow and Nofollow Links Actually Differ for SEO
| Factor | Dofollow | Nofollow |
| Passes PageRank | Yes | Generally no (hint-based since 2019) |
| Counts as ranking signal | Directly | Potentially, depending on context |
| Drives referral traffic | Yes | Yes |
| Contributes to natural link profile | Yes | Yes |
| Helps search engines discover pages | Yes | As of March 2020, yes |
| Risk of penalty if misused | Yes (link schemes) | Lower |
The table above illustrates that the gap between the two has narrowed meaningfully. Nofollow links may not pass PageRank in most cases, but they contribute to crawl discovery, natural link profile diversity, brand visibility, and referral traffic. These are real SEO and business benefits.
The Critical 2019 Update: Nofollow Became a Hint, Not a Directive
This is the single most important thing to understand about nofollow links in 2026.
On September 10, 2019, Google officially announced that it was changing how it processes nofollow attributes. Prior to this update, Google treated nofollow as a strict directive: follow this link? No. Pass PageRank? No. Full stop. That changed.
As Google stated in its official announcement, all link attributes, including sponsored, UGC, and nofollow, are now treated as hints about which links to consider or exclude within Search. Google uses these hints alongside other signals to better understand how to analyze links across the web.
This is not a minor semantic shift. It means Google reserves the right to use a nofollow link as a ranking signal if its algorithms determine the link is relevant and credible. In most cases, nofollow links will still be treated as they were before: Google will generally not count them for ranking purposes. But “generally” is doing a lot of work in that sentence. Google can and sometimes does use nofollow links when context warrants it.
Alongside this update, Google also introduced two new, more specific link attributes:
The Four Link Attribute Types in 2026
Most guides treat this topic as a binary: dofollow or nofollow. That framing misses important nuance. There are now four distinct link behaviors to understand.
1. Dofollow (Default)
No attribute required. Passes link equity. Use for editorial links you genuinely endorse, internal links between your own pages, citations to original research, and links to authoritative external resources.
2. rel=”nofollow”
A hint that the link should not pass ranking credit. Use when you want to link without implying editorial endorsement, for example when referencing a source you find questionable, or when linking to content outside your niche.
3. rel=”sponsored”
Introduced in September 2019. Use this for any link created as part of an advertisement, paid placement, sponsorship, or affiliate arrangement. Google prefers this over nofollow for paid links. Failing to mark commercial links appropriately can risk a manual action from Google’s spam team.
4. rel=”ugc” (User-Generated Content)
Also introduced in 2019. Use for links appearing in user-generated content such as blog comments, forum posts, and community contributions. Many platforms like WordPress apply nofollow to comments by default; the ugc attribute offers greater specificity.
Attributes can also be combined. A sponsored link in a forum post could appropriately use rel=”ugc sponsored”, for instance.
HTML Example Table
| Link Type | HTML Example | Best Used For |
| Dofollow | <a href=”https://example.com”>Anchor Text</a> | Editorial links, internal links, trusted citations |
| Nofollow | <a href=”https://example.com” rel=”nofollow”>Anchor Text</a> | Links you don’t want to explicitly endorse |
| Sponsored | <a href=”https://example.com” rel=”sponsored”>Anchor Text</a> | Paid, affiliate, or sponsored links |
| UGC | <a href=”https://example.com” rel=”ugc”>Anchor Text</a> | Blog comments, forums, and other user-generated content |
Why Nofollow Links Still Matter
1. A Natural Link Profile Includes Both Types
A backlink profile consisting almost entirely of dofollow links can appear artificial to Google. Before drawing conclusions about your backlink profile, it’s important to identify dofollow and nofollow links accurately rather than relying on total backlink counts alone.
Most major publishing platforms, social networks, Wikipedia, Reddit, and many news outlets default to nofollow for outbound links. If your site has accumulated thousands of backlinks and nearly all of them are dofollow, that pattern may suggest deliberate link acquisition rather than organic recognition.
An analysis of top-performing domains across multiple industries typically shows a meaningful proportion of nofollow links in their profiles. That proportion is a signal of naturalness, not a weakness.
2. Referral Traffic Has Real Value
A nofollow link from a high-traffic publication can send more targeted visitors to your site than a dofollow link from an obscure blog. That traffic may convert, subscribe, share your content, or link to it themselves with dofollow links. The SEO value of nofollow links is often indirect but measurable.
3. Brand Mentions and Authority Signals
Platforms like Wikipedia, major news sites, and industry forums frequently link with nofollow. A nofollow mention on Wikipedia may still reinforce brand recognition, entity signals, and the kind of citation patterns that AI search engines are increasingly factoring into their outputs.
4. AI Search and Citation Behavior
Research published in 2026 suggests that AI-powered search engines, including ChatGPT, Google AI Overviews, and Perplexity, treat dofollow and nofollow links as nearly equivalent signals for citation and sourcing decisions. The correlation between backlink types and AI search visibility is reportedly very close. This makes a balanced, credible link profile more important than a dofollow-only one.
5. Nofollow Links Can Attract Dofollow Links
When your content earns visibility across platforms, some of those nofollow links can act as discovery pathways. Editors, bloggers, and researchers who find your content via a nofollow citation may later link to it editorially with a dofollow link.
When to Use Nofollow on Your Own Links
Knowing when to apply nofollow to links on your own site matters as much as understanding where to earn nofollow backlinks.
Use nofollow (or sponsored/ugc) on your outgoing links in these situations:
- Paid or sponsored links: Always use rel=”sponsored” or rel=”nofollow” for affiliate links, advertorials, paid placements, or sponsored content. This is a Google policy requirement, not a suggestion.
- User-generated content: Apply rel=”ugc” to links in comments, forums, and community areas to prevent passing authority to potentially spammy destinations.
- Untrusted or low-quality sites: If you need to reference a source you do not vouch for, nofollow signals that clearly to Google.
- Login pages, cart pages, and other utility pages: These are rarely worth indexing. While nofollow on internal links is generally not recommended and does not redistribute PageRank (that behavior changed in 2009), blocking these pages from unnecessary crawling is better handled via other methods such as noindex or robots.txt.
Do not use nofollow on:
- Internal links between your own content pages. Every internal link should be dofollow. Nofollowing internal links does not sculpt PageRank in the way it once appeared to. The authority assigned to nofollowed links effectively disappears rather than redistributing to other links.
- External links you genuinely want to endorse. If you’re citing a high-quality source or referencing research, a dofollow link is appropriate and signals confidence in the destination.
Common Misconceptions About Dofollow and Nofollow Links
“Nofollow links are worthless.”
This was arguably true before 2019. It is no longer accurate. Nofollow links contribute to profile naturalness, brand discovery, referral traffic, and potentially to ranking signals when Google’s algorithms deem the context relevant.
“More dofollow links always means better rankings.”
Quality, relevance, and diversity matter more than raw quantity of dofollow links. A dofollow link from an unrelated, low-authority site may provide less value than a nofollow mention from a trusted industry publication.
“I should nofollow all external links to hoard PageRank.”
This approach, sometimes called PageRank sculpting, was popular in the mid-2000s but has not worked in the intended way since Google updated its behavior in 2009. Nofollowing external links on your site generally does not strengthen the PageRank passed to your other pages.
“A 95% dofollow backlink ratio is a sign of a strong profile.”
Counterintuitively, a very high dofollow ratio may actually look unusual to Google, since naturally acquired links from social platforms, news publications, and community sites tend to default to nofollow. A profile that is heavily skewed toward dofollow links may suggest deliberate link buying.
How to Check Whether a Link Is Dofollow or Nofollow
There are several practical methods to inspect link attributes:
Browser Developer Tools: Right-click any link on a webpage, select “Inspect” or “Inspect Element,” and look for rel=”nofollow”, rel=”sponsored”, or rel=”ugc” in the anchor tag. If no rel attribute appears, the link is dofollow by default.
Page Source: Use Ctrl+U (or Cmd+U on Mac) to view the raw HTML of a page, then search for the anchor tag in question.
SEO Browser Extensions: Tools like MozBar, Ahrefs SEO Toolbar, or similar extensions can highlight link types visually as you browse.
Backlink Analysis Tools: Platforms such as Ahrefs, Semrush, and Moz allow you to filter your backlink profile by link type, making it easy to assess your dofollow vs nofollow ratio at scale.
Building a Balanced Link Strategy in 2026
Given everything above, here is how to approach link building in a way that reflects the current state of search:
Prioritize editorial dofollow links. These remain the most direct path to passing authority and improving search rankings. Focus on creating content others want to cite, pursuing guest posts on relevant publications, and earning mentions from authoritative sites in your industry.
Do not dismiss nofollow opportunities. A nofollow link from a high-traffic industry site, a relevant news publication, or a trusted community platform can still drive traffic, build brand recognition, and contribute to a credible link profile.
Use the correct attribute for paid links. Using rel=”sponsored” or rel=”nofollow” on commercial links is required by Google’s guidelines. Violating this can result in a manual penalty that is significantly harder to recover from than simply having a suboptimal link profile.
Focus on relevance over quantity. A smaller number of links from topically relevant, trusted sources is generally more valuable than a high volume of links from unrelated sites, regardless of whether they are dofollow or nofollow.
Track your profile over time. Regular audits of your backlink profile help you spot unusual patterns, identify spammy links that may be pointing to your site, and understand how your ratio of dofollow to nofollow links is evolving. A monthly review is a reasonable starting point for most sites.
Think beyond traditional backlinks. In 2026, brand mentions, entity signals, and citations in AI-generated search responses are increasingly important. A strategy that builds genuine authority across a range of credible sources, with or without followed links, is more durable than one focused narrowly on dofollow link counts.
Conclusion
The dofollow vs nofollow debate has become considerably less black and white since Google’s 2019 policy change. Dofollow links remain the most reliable mechanism for passing link equity and signaling endorsement to search engines. However, nofollow links now operate as hints rather than blanket exclusions, contribute meaningfully to profile diversity, and can deliver genuine traffic and brand value.
In 2026, a healthy approach to link building is not about chasing one type at the expense of the other. It is about earning credible mentions from relevant sources, using the right attributes to accurately signal the nature of your links, and building a profile that looks the way a genuinely authoritative site’s profile naturally looks: a mix of both.
Understanding how different link attributes work is worthwhile. Chasing an arbitrary dofollow-to-nofollow ratio is not.
