Dofollow Links Explained: What They Are and Why They Fail

What Does "Dofollow" Actually Mean?

Search a hundred SEO glossaries and you'll find a hundred confident definitions of "dofollow link." Almost none mention the truth: dofollow is not an HTML attribute, not a rel value, and not something you add to a link's markup. There is no rel="dofollow" that browsers or Google Search Central recognize as valid.

The dofollow meaning comes from the absence of something, not the presence of it. When a link has no rel="nofollow", rel="sponsored", or rel="ugc" attached, the SEO community calls it "dofollow" — shorthand for "this link is eligible to pass PageRank and other ranking signals normally." So what is a dofollow link, technically? A plain, unmarked tag with no attribute telling crawlers to treat it differently.

The term was invented by SEOs, not Google, to describe a default state. Once you understand that, the confusion around "do I need to add dofollow to my links" disappears — you don't add anything. You simply avoid adding a nofollow-family attribute if you want a link to carry full weight.

Dofollow vs. Nofollow vs. Sponsored vs. UGC

Every link on the web sits in one of four states:

Dofollow (unmarked) — the default. No rel attribute restricting how the link is treated, so it's eligible to pass link equity and gets crawled as a normal endorsement.

Nofollow (rel="nofollow") — originally a strict instruction telling Google not to pass ranking credit through the link. Common on comment sections, forum signatures, and content you don't want to vouch for editorially.

Sponsored (rel="sponsored") — flags a link created as part of an advertising, affiliate, or paid placement arrangement. Any link tied to compensation, including affiliate links, should carry this attribute.

UGC (rel="ugc") — marks links generated by users, such as blog comments, forum posts, or reviews, distinguishing them from links the site owner placed intentionally.

The dofollow vs nofollow distinction matters most when deciding what to endorse. If you're linking to a source you trust with no financial relationship, leave it unmarked. If money changed hands, rel=sponsored is correct, not a plain nofollow. If a visitor posted the link, rel=ugc is more accurate. You can also combine values (rel="nofollow sponsored") when more than one condition applies.

Why Google Changed the Rules in 2019 (and What Changed)

For over a decade, nofollow meant one thing: don't count this link, full stop. That changed in September 2019, when Google introduced rel=sponsored and rel=ugc alongside a quieter but more consequential shift — nofollow became a hint rather than a strict directive, as InMotion Hosting's breakdown of the update confirms.

In practice, Google now reserves the right to use nofollow, sponsored, or ugc links as a crawling and ranking signal if context warrants it, rather than blindly ignoring them. A nofollow hint doesn't guarantee a link is completely ignored, and it doesn't guarantee a "dofollow" link's value is fully passed either. Google weighs link placement, surrounding content, and site trustworthiness before deciding how much weight any link carries. As Conductor's explainer on nofollow puts it, "dofollow" was never an official term to begin with; it's just the absence of a directive, and Google has always retained discretion over how literally it treats any rel attribute.

How to Check If a Link Is Dofollow

You don't need expensive software to answer "how to check dofollow links" for a single page. Three methods cover most situations:

1. View source or inspect element. Right-click the link, choose Inspect, and look at the tag's rel attribute. No nofollow, sponsored, or ugc present means it's dofollow by default.
2. Browser extensions. Several free extensions highlight nofollow links directly on the page, color-coding them so you don't have to inspect each one manually — useful when auditing a page with dozens of outbound links.
3. Bulk audit tools. For checking link attributes across an entire site or backlink profile, a crawler-based audit tool is far faster than manual inspection and catches inconsistencies humans miss, like a nofollow tag applied inconsistently across templates.

Whichever method you use, the goal is the same: confirm what's actually in the markup rather than assuming a link is dofollow just because it looks like a normal blue underlined link in the browser.

When a "Dofollow" Link Still Doesn't Pass Value

Here's where most dofollow advice stops short. Confirming a link has no nofollow, sponsored, or ugc attribute tells you it's technically eligible to pass value — it doesn't guarantee that value actually arrives. A dofollow link not working as expected usually comes down to something happening after the crawler follows it, not the rel attribute itself.

Common causes of lost link equity include:

• Broken or chained redirects. If a dofollow link points to a URL that hops through several 301s before landing on the final page, some authority can be diluted along the way. See how redirects can drain your SEO for the mechanics.
• Malformed URLs. A link with encoding errors, stray characters, or an incorrect path can fail to resolve cleanly, meaning crawlers can't associate the link equity with the intended page. Optimevra's guide to malformed URLs covers common culprits.
• JavaScript-rendered links. If a link's href is generated or altered via JavaScript rather than present in the initial HTML, some crawlers may never parse it as a link at all. This guide to JavaScript URL issues explains the crawling, accessibility, and security fallout.
• Redirect loops or blockers on your own domain. Sometimes the fault sits entirely on the receiving end — see Redirect Blocker: When the Problem Is Your Own Website.
• Noindex pages. A dofollow link pointing at a page marked noindex still gets crawled, but the destination itself won't be eligible to rank, wasting the referral.

None of these issues involve the rel attribute at all — they're technical problems that quietly neutralize link equity your backlink profile should be delivering.

Auditing Your Site's Link Health

Understanding dofollow versus nofollow, sponsored, and ugc is table stakes. The bigger return comes from confirming that the dofollow links pointing at your site aren't being wasted by redirect chains, malformed URLs, or JS-rendered paths crawlers can't follow. A link audit tool that checks both attribute status and technical delivery gives you a far more accurate picture of your actual link equity than a backlink count ever will.

A proper website link health check should tell you not just how many dofollow backlinks you have, but whether each one resolves cleanly, lands on an indexable page, and survives the crawl path without errors. That's the gap between counting links and actually benefiting from them.

Understanding dofollow only pays off if the links on your own site are structurally sound enough to pass that value through — broken redirects, malformed URLs, and JavaScript-rendered links can silently neutralize even a technically clean dofollow link.

Frequently Asked Questions

Is dofollow a real tag I need to add to my links?

No. There is no rel="dofollow" attribute recognized by browsers or search engines. "Dofollow" is SEO shorthand describing a link with no nofollow, sponsored, or ugc attribute — it's the default state, not something you add.

What's the difference between a dofollow link and a nofollow link?

A dofollow link has no restricting rel attribute and is eligible to pass link equity normally, while a nofollow link carries rel="nofollow", signaling that the site owner doesn't want to vouch for or pass ranking credit to the destination. Since 2019, Google treats nofollow as a hint it can weigh rather than an absolute instruction.

Do dofollow backlinks still matter for SEO in 2026?

Yes, unmarked dofollow links remain a meaningful ranking signal because they represent an unrestricted editorial endorsement from one site to another. However, their value depends heavily on the receiving page being crawlable, indexable, and free of redirect or URL errors that block equity from landing.

How do I know if a backlink I got is dofollow or nofollow?

Inspect the link's HTML using your browser's "Inspect Element" tool and check the tag for a rel attribute. If no nofollow, sponsored, or ugc value is present, it's dofollow by default; browser extensions or bulk audit tools can do this automatically across many links.

Should I use nofollow, sponsored, or ugc for affiliate links?

Affiliate and other compensated links should use rel="sponsored", since that's the attribute Google introduced specifically to flag paid or commercial relationships. You can combine it with nofollow if you also want to withhold an editorial endorsement.

Can a dofollow link fail to help my rankings?

Yes. A link can be technically dofollow yet still fail to pass meaningful value if it points to a noindex page, gets caught in a broken or chained redirect, contains a malformed URL, or relies on JavaScript that crawlers can't parse as a real href. The rel attribute being correct doesn't guarantee the link equity actually reaches its destination.
