What Is Dofollow Link In SEO

A dofollow link is any ordinary hyperlink that does not carry the rel="nofollow", rel="ugc", or rel="sponsored" attribute. Search engine crawlers can follow these links, and they may pass ranking value, often called link juice, from one page to another. The term gets used as if dofollow were a special tag. It is not. It is simply what a link looks like by default.

That small misunderstanding drives most of the confusion around link building. Beginners search for a “dofollow extension” or copy code snippets that do not exist, then wonder why nothing changes. The rest of this article clears that up, and shows what actually decides whether a link passes authority.

The Misconception That Confuses Most Beginners

There is no rel="dofollow" attribute in HTML. The HTML specification defines nofollow, ugc, and sponsored, but it has never defined dofollow. The word is shorthand that SEO practitioners invented to describe a regular link that lacks any restrictive directive.

Beginners stumble on this because most SEO blogs talk about dofollow and nofollow as if they were two equal tags. They write “add a dofollow attribute” or “make this link dofollow,” as if you could toggle a switch. You cannot. The actual switch works the other way: you add a rel attribute when you want to restrict a link, and you leave it off when you do not.

That distinction matters because it changes how you think about link building. Instead of asking “how do I get more dofollow links,” the better question becomes “when should a link be marked, and when should it be left alone.” That framing lines up with how Google’s outbound link guidance treats the three real attributes, and it matches the actual HTML. It is the same approach Clickside takes when auditing link profiles for client sites.

What Actually Makes a Link Dofollow or Not

Three attributes, and only three, can turn an ordinary link into something other than dofollow:

• rel=”nofollow” tells crawlers the link should not be treated as an editorial endorsement for ranking purposes.
• rel=”ugc” marks links inside user-generated content, such as comments, forum posts, and wiki edits.
• rel=”sponsored” identifies paid or advertising placements, including affiliate links and sponsored posts.

Any anchor tag without one of these three values is treated as dofollow. That includes most editorial links, internal navigation links, and the references you add when you cite another site in a blog post. The official MDN reference for the rel attribute lists the same three values, and the HTML specification does not include a dofollow equivalent.

One common mix-up: nofollow does not always block crawling, even though the name suggests otherwise. Google’s outbound link documentation makes clear that nofollow mainly changes how a link is treated as a ranking signal. Crawlers can still discover the destination in some cases, and they often will. Use nofollow, ugc, or sponsored when the link’s purpose is not an editorial endorsement, not as a way to hide a page from search engines.

How Dofollow Links Pass Link Equity

Link equity, more commonly called link juice, is the informal SEO term for the ranking or authority value that may travel through a dofollow link from the referring page to the destination. When a respected industry publication links to your research article with a plain anchor tag, some of that authority can flow to your page and help it rank for related queries.

The amount that passes is not a fixed number. It depends on relevance, the authority of the referring domain, where the link sits on the page, and the editorial context around it. A link buried in a sidebar template is worth less than one woven into the body of a relevant article. A link from a closely related site is worth more than one from an unrelated directory. Treat link equity as a weighted signal, not a simple vote.

That is why editorial links from relevant, trustworthy pages are usually the most valuable dofollow backlinks a site can earn. A handful of strong, topically aligned links routinely outperforms dozens of weak ones. Industry resources on link building reach the same conclusion: link quality beats link quantity, almost every time.

How to Tell If a Link Is Dofollow

Open the page, right-click the link, and inspect its HTML. If the anchor tag reads something like <a href="https://example.com">Example</a>, the link is dofollow. If it carries rel="nofollow", rel="ugc", or rel="sponsored", it is not.

For larger sites, a quick four-step audit works well:

1. Pick a sample page and open the source.
2. Search for “rel=” and scan the anchor tags.
3. For site-wide checks, run an SEO crawler.
4. For inbound link audits, use a backlink checker to classify referring domains by attribute.

Pair the inspection with intent. Sponsored or paid placements should carry rel="sponsored". Links inside comments, forums, and other user content should carry rel="ugc" or rel="nofollow" if ugc is too narrow. Editorial links from your own content can stay dofollow. The right attribute is the one that matches the link’s real purpose. When the audit gets messy, the Clickside team can help prioritize which fixes matter most.

The Real Lesson Behind the Label

Dofollow is the default state of a link, not a tag to add. The actual work in SEO is earning relevant editorial links and applying restrictive attributes only where they honestly apply: sponsored for paid placements, ugc for user-generated content, nofollow as a general signal that a link is not editorial. Get those right and the dofollow question largely takes care of itself.

A useful next step is to audit ten links today. Pick five outbound links from your own site and five inbound links from referring domains, then check whether each one has the rel attribute that fits its purpose. You will likely find at least one mismatch, and that mismatch is where your next small SEO win lives.
