A dofollow link is the default kind of hyperlink — one that search engines are free to crawl and that passes ranking signals (what people still call “link equity” or “link juice”) from the linking page to its target. There’s no actual rel="dofollow" attribute; a link is “dofollow” simply by not carrying a rel="nofollow", rel="sponsored", or rel="ugc" value. In practice, that makes dofollow links the editorial votes of confidence that move authority around the web — and the ones worth earning.
Dofollow Link
A dofollow link is a standard HTML hyperlink with no rel="nofollow", rel="sponsored", or rel="ugc" attribute, so search engines may follow it and pass ranking signals from the source page to the destination.
How a Dofollow Link Actually Works
The naming is a historical accident worth clearing up first: “dofollow” is not a real HTML value. You never write rel="dofollow". The browser and the crawler treat a plain link — <a href="..."> — as followable by default. “Dofollow” is just the community’s shorthand for the absence of a follow-restricting attribute.
When Googlebot and other crawlers hit a dofollow link, two things happen:
- Discovery. The crawler can follow the URL to find and queue the destination page for indexing. Dofollow links are a primary way new pages get found.
- Signal flow. The link counts as an endorsement. A portion of the source page’s authority — historically modeled as PageRank — flows to the target, contributing to how it ranks for relevant queries.
Both halves matter. A nofollow link might still drive traffic and brand exposure, but a dofollow link is the one that participates fully in Google’s link graph.
What governs how much value flows
Not all dofollow links are equal. The weight a single link carries depends on a stack of factors:
- Source authority. A dofollow link from an established, trusted domain in your niche is worth far more than one from a thin, unknown site.
- Topical relevance. A link between two pages about the same subject passes stronger, cleaner signals than an off-topic mention.
- Link prominence. A link inside the main editorial body outperforms one buried in a footer, sidebar, or comment thread.
- Dilution. A page splits its outgoing authority across all its outbound links. A link from a page with 5 outbound links concentrates more value than one from a page firing off 200.
- Anchor text. Descriptive, natural anchor text tells search engines what the target is about. Over-optimized, repetitive exact-match anchors look manipulative and can backfire.
Practitioner note: We don’t chase “dofollow” as a checkbox. We chase relevant, editorially earned dofollow links. A single contextual link from the right industry publication beats fifty dofollow directory listings — and Google has spent a decade learning to discount the latter.
Dofollow vs. Nofollow vs. Sponsored vs. UGC
The rel attribute is where the real distinctions live. Since 2019, Google has treated nofollow and its newer siblings as hints rather than strict directives — meaning Google may still use them for ranking and crawling, but it’s no longer obligated to ignore them entirely.
| Link type | rel value | Passes ranking signals? | Typical use |
|---|---|---|---|
| Dofollow | (none) | Yes (full) | Editorial links, internal links, trusted citations |
| Nofollow | rel="nofollow" | Treated as a hint | Untrusted or unvetted external links |
| Sponsored | rel="sponsored" | Treated as a hint | Paid links, ads, affiliate links |
| UGC | rel="ugc" | Treated as a hint | Comments, forum posts, user submissions |
If you’re disclosing a paid placement, use rel="sponsored" — not nofollow — to stay aligned with Google’s link-spam guidelines. For deeper breakdowns, see our entries on nofollow links and UGC links. You can stack values too: a paid link inside a comment can carry rel="sponsored ugc".
Why the “hint” shift matters
Before 2019, a nofollow link was a hard wall: no signal passed, full stop. Today, Google reserves the right to learn from any link. The practical upshot for a link-building strategy: stop obsessing over whether a link is technically dofollow. A nofollow mention from a major publication still builds brand entity strength, drives referral traffic, and feeds the broader picture Google assembles about your authority.
How Dofollow Links Fit a Modern SEO Strategy
Dofollow links remain one of the strongest ranking factors Google has publicly acknowledged — but the way you earn them has changed in the AI-era SERP.
In the AI Overviews and AI-assisted search landscape, links do double duty. They still pass classic ranking signals, and they help establish the entity-level trust and corroboration that large language models lean on when deciding which sources to cite. A page that’s widely linked from authoritative, on-topic sites is more likely to be pulled into an AI Overview as a source. Authority earned through real dofollow links is increasingly the moat that keeps you visible when the answer is synthesized above the ten blue links.
Internal dofollow links are the cheap win
Most teams fixate on external backlinks and ignore the authority they already control: internal links. Every internal link on your own site is dofollow by default and distributes ranking value across your pages. A deliberate SEO site structure — flowing equity from high-authority pages into the commercial and pillar pages you actually want ranking — is the single most underrated lever in technical SEO. You own it, it’s free, and it ships today.
Earning external dofollow links
Strategic priorities, in order of payoff:
- Make pages link-worthy. Original data, tools, and genuinely useful resources earn links without asking. This is the foundation of getting backlinks that stick.
- Pursue topical relevance over raw volume. Ten links from your niche beat a hundred from random blogs.
- Keep anchor text natural. Branded and descriptive anchors, not a wall of exact-match commercial phrases.
- Vet your own outbound links. Linking out to quality, relevant sources is a trust signal; linking to spam is a liability.
This is the work behind our AI SEO services and growth program: earning the kind of authority that survives algorithm shifts and AI-driven SERP changes — no dashboard theater, just links that compound.
Frequently Asked Questions
Is there a rel=“dofollow” attribute in HTML?
No. There is no rel="dofollow" value in HTML. A link is “dofollow” by default — simply by being a standard <a href="..."> link with no rel="nofollow", rel="sponsored", or rel="ugc" attribute. “Dofollow” is informal SEO shorthand for the absence of a follow-restricting attribute, not something you actually code.
How do I check if a link is dofollow or nofollow?
Inspect the link’s HTML: right-click the link, choose “Inspect,” and look at the <a> tag. If it includes rel="nofollow", rel="sponsored", or rel="ugc", it restricts following. If the rel attribute is absent or doesn’t contain those values, it’s a dofollow link. Browser extensions and SEO crawlers can also flag link types in bulk.
Do dofollow links still matter with AI Overviews and AI search?
Yes. Dofollow links still pass core ranking signals, and they now help establish the entity authority and corroboration that AI Overviews use when selecting sources to cite. Pages backed by relevant, authoritative dofollow links are more likely to rank and to be surfaced inside AI-generated answers, making them more valuable, not less.
Are nofollow links useless for SEO?
No. Since 2019 Google treats nofollow as a hint, meaning it may still factor those links into ranking and crawling. Even setting that aside, nofollow links from strong sites drive referral traffic, build brand recognition, strengthen your entity profile, and create a natural-looking link mix. A profile of only dofollow links can itself look manipulative.
Should internal links be dofollow?
Almost always, yes. Internal links are dofollow by default and let you steer ranking value toward your most important pages — pillar content, service pages, and high-intent commercial pages. Avoid adding nofollow to internal links to “sculpt” PageRank; modern Google guidance treats that as ineffective and potentially wasteful of your own crawl equity.
