The difference between dofollow and nofollow links sounds technical, but the basic idea is simple: the link may look identical to a visitor, while the HTML behind it tells search engines how the relationship should be treated. Understanding the distinction helps you evaluate backlinks realistically, mark outbound links correctly, and avoid outdated advice.
In SEO, “dofollow” describes a normal link that can be crawled and considered as a ranking signal. A nofollow link asks search engines not to treat it as a standard endorsement. Google interprets these link attributes as hints rather than rigid commands.
What Is a Dofollow Link?
A dofollow link is a regular hyperlink without a qualifying rel value such as nofollow, sponsored, or ugc. There is no official rel=”dofollow” attribute. Search engines can discover the destination, crawl it, interpret the anchor text, and potentially use the link when evaluating the page.
A standard editorial link might appear as <a href=”https://example.com”>helpful SEO guide</a>. Because no restrictive link attributes are attached, a search engine is free to process it normally.
This does not mean every dofollow link improves rankings. Its value depends on relevance, placement, authority, editorial intent, and page quality. A natural link from a trusted article may help, while manipulated or low-quality links may provide little benefit.
What Is a Nofollow Link?
A nofollow link contains the rel nofollow value, such as <a href=”https://example.com” rel=”nofollow”>example</a>. It tells a search engine that the publisher does not want the link treated like an ordinary editorial endorsement.
Nofollow was introduced to combat comment spam and later became common for advertising, untrusted references, and user-added links. Google now treats nofollow, sponsored, and ugc as hints. The nofollow SEO impact is therefore more nuanced than the claim that these links are always ignored.
A nofollow link will generally not pass ranking credit like a normal editorial link. However, it may still be discovered or crawled. It can also send referral traffic, build awareness, and lead to future editorial mentions.
Dofollow vs Nofollow Links: The Practical Difference
How search engines interpret them
A standard dofollow link gives search engines no special qualification, so it can be followed and evaluated normally. A nofollow link indicates that the site does not want to make a conventional endorsement or would prefer the destination not to be associated with the link in the usual way.
Potential ranking value
Dofollow links are more likely to pass ranking signals, but no link guarantees a ranking increase. Nofollow links generally have less direct SEO value, yet they are not automatically useless. Search engines evaluate links within a much broader system, and Google describes these attributes as hints.
What visitors see
Visitors usually cannot tell whether a link is dofollow or nofollow. Both can be clicked and generate traffic. The distinction exists mainly in the source code and in how search engines process it.
When Should You Use Nofollow, Sponsored, or UGC?
Use rel=”sponsored” for advertisements, paid placements, sponsorships, affiliate links, or other compensated arrangements. Google prefers sponsored for paid links, although nofollow remains acceptable for that purpose.
Use rel=”ugc” for links in user-generated content, such as forum posts and public comments. This separates a site owner’s editorial choices from links submitted by users. Multiple values can be combined when appropriate, such as rel=”ugc nofollow”.
Use rel=”nofollow” when sponsored or ugc does not fit and you do not want to imply endorsement. This may apply when citing a page you do not fully trust or linking to an unverified claim. Regular editorial links to useful, relevant resources do not need a special rel value.
Does Nofollow Stop Crawling or Indexing?
Not reliably. Nofollow is not the correct tool for preventing a page from appearing in search results. A search engine may discover the URL through another website, a sitemap, an internal link, or a previous crawl. Even if one link is nofollowed, the destination can still be crawled or indexed through other routes.
To control indexing, use an appropriate noindex directive while allowing the crawler to access the page. To control crawling on your own site, use robots.txt where suitable. These mechanisms solve different problems, so nofollow should not be treated as a substitute for technical index management.
Do You Need Both Types of Backlinks?
A natural backlink profile often contains standard and nofollow links because genuine mentions come from many sources. News sites, social platforms, directories, forums, and review pages may apply different attributes automatically. Chasing only dofollow links can distract from relevance, audience value, and editorial quality.
Focus on whether a placement is trustworthy, contextually relevant, visible to real readers, and capable of sending qualified traffic. A strong nofollow mention on a respected publication may be more valuable commercially than a dofollow link buried on an unrelated, low-quality page.
There is no ideal dofollow-to-nofollow ratio. Build content and relationships that earn credible mentions, then assess each link by its source, context, traffic potential, and long-term value.
Common Misunderstandings About Link Attributes
One myth is that nofollow links have zero value. They may not pass conventional ranking credit, but they can generate traffic, awareness, citations, and secondary links. Another myth is that adding rel=”dofollow” strengthens a link. It does not; a normal link already behaves as an unqualified link.
It is also wrong to assume every dofollow link is beneficial. Search engines can discount links that appear manipulative, irrelevant, paid without proper qualification, or created mainly to influence rankings. Link quality and intent matter far more than the label alone.
Frequently Asked Questions
Are dofollow links better than nofollow links?
Dofollow links usually have more potential to contribute direct ranking signals, but “better” depends on the source and purpose. A relevant nofollow link that sends customers or earns visibility can be more useful than a weak dofollow link.
Can nofollow links help SEO?
Yes, often indirectly. They can drive referral traffic, increase brand discovery, support a natural backlink profile, and lead to additional mentions. Google may also use nofollow as a hint rather than ignoring it in every case.
How can I check whether a link is nofollow?
Inspect the link in your browser’s developer tools or view the page source. Look for rel=”nofollow”, rel=”sponsored”, or rel=”ugc” in the link markup. If none is present, it is normally treated as a standard link.
Should all external links be nofollow?
No. Editorial links to useful, trusted sources do not need nofollow. Use the appropriate attribute when a link is paid, user-generated, untrusted, or not intended as an endorsement.
Conclusion
The dofollow vs nofollow links debate becomes easier once you stop viewing it as a choice between valuable and worthless. A normal dofollow link can pass ranking signals, while nofollow qualifies the relationship and is generally treated more cautiously. Sponsored and ugc add clarity for paid and user-generated links.
For practical SEO, use link attributes honestly, do not rely on nofollow to control indexing, and judge backlinks by relevance, trust, placement, and real audience value. That approach is more accurate and useful than chasing labels alone.
