What Exactly Is a Nofollow Link?
A nofollow link is a hyperlink with a rel="nofollow" attribute in its HTML code. This attribute tells search engines that the linking site does not want to pass its authority or endorsement to the destination page. In practical terms, it is a way of saying “I am linking to this, but I am not vouching for it.”
Google introduced the nofollow attribute in 2005 in direct response to the spam epidemic in blog comments. Spammers were flooding comment sections across the web with links to their own sites, artificially inflating their rankings. The nofollow tag gave website owners a way to allow user-generated links without inadvertently boosting spam sites with free link equity.
Since then, nofollow has become a standard part of web hygiene. Major platforms like WordPress automatically apply nofollow to comment links. Social media networks use it across all outbound links. Press release distribution services apply it to links in syndicated content. It is deeply embedded in how the modern web operates.
Understanding nofollow links is essential for anyone investing in SEO, because they play a specific and important role in how search engines evaluate your backlink profile and your website’s overall authority.
How Google Treats Nofollow Links in 2026
Google’s treatment of nofollow has shifted significantly since the tag was introduced two decades ago. Originally, nofollow was a strict directive. Google’s crawlers completely ignored nofollow links when calculating PageRank and determining rankings. A nofollow link was essentially invisible to the algorithm.
In September 2019, Google made a landmark change. Nofollow became a hint rather than a directive. This means Google may choose to crawl, index, and even pass some ranking value through nofollow links when it determines this would improve search quality. Google’s algorithms now make case-by-case decisions about nofollow links rather than applying a blanket rule.
Google also introduced two additional link attributes alongside this change:
- rel=”sponsored” for paid links, advertisements, and sponsorships. This tells Google the link exists because of a commercial relationship
- rel=”ugc” for user-generated content like comments, forum posts, and community contributions. This signals that the link was created by a user, not the site owner
You can use these attributes individually or combine them (for example, rel="nofollow ugc"). All three signal to Google that the link should be treated with caution regarding link equity transfer. The distinction between them gives Google more nuanced information about why the link exists.

When You Should Use Nofollow on Your Own Website
As a website owner, there are several situations where applying nofollow to your outbound links is the right practice. Getting this right protects your site from penalties and demonstrates to Google that you manage your link equity responsibly.
- User-generated content: Comments, forum posts, testimonials, and community submissions should always use nofollow or ugc attributes. You cannot vet every link your users post, and if one of those links points to a spammy site, you do not want Google associating your site with it
- Paid links and sponsorships: Any link you received compensation for must be marked as nofollow or sponsored. This is not optional guidance, it is a requirement from Google. Failing to tag paid links is one of the most common reasons businesses receive manual penalties
- Affiliate links: Product referral links where you earn a commission should carry the nofollow or sponsored attribute. This applies to Amazon affiliate links, Shopee partner links, and any similar programme
- Untrusted or unverified sources: If you need to link to a source you cannot fully verify or endorse, such as referencing a competitor’s claim or citing an unverified statistic, nofollow protects your site’s reputation
- Login and registration pages: These pages do not need to be crawled or indexed, so nofollow helps direct Google’s limited crawl budget toward your important, revenue-generating content
Using nofollow appropriately shows Google that you are a responsible webmaster who manages link equity thoughtfully. This contributes to the overall trust signals that support your rankings.
The Real SEO Value of Nofollow Links
Despite not passing direct link equity in most cases, nofollow links deliver genuine, measurable value to your SEO and broader business goals. Dismissing them entirely is a mistake that costs businesses traffic and opportunities.
Referral traffic. A nofollow link on a high-traffic site still sends visitors to your pages. That traffic can convert into leads and customers regardless of the link attribute. A nofollow link from The Straits Times that drives 500 visitors to your site is far more valuable than a dofollow link from an obscure blog that sends zero traffic.
Brand awareness and trust. Mentions on major platforms, social media, and industry forums increase your visibility even when the links are nofollow. Every time someone encounters your brand name in a credible context, it builds recognition and trust that influences their behaviour when they later see you in search results.
Natural link profile. A healthy backlink profile contains a mix of dofollow and nofollow links. Google expects this because it mirrors how links naturally occur on the web. A profile with zero nofollow links looks artificial and may trigger closer algorithmic scrutiny.
Indirect link acquisition. This is the most underestimated value of nofollow links. Content that gets shared widely through nofollow channels, social media, newsletters, forums, gains exposure that leads to dofollow editorial links from bloggers and journalists who discover your content through those channels. Nofollow links are often the catalyst for the dofollow links that move rankings.
Common Mistakes Singapore Businesses Make with Nofollow Links
Nofollowing every outbound link. Some website owners nofollow every outbound link on their site, thinking this “preserves” their link equity. In reality, this looks unnatural to Google and removes the trust signals that editorial outbound links provide. Linking to authoritative, relevant sources without nofollow actually helps your content’s credibility. Google’s algorithms evaluate whether your page references quality sources, and nofollowing everything suggests you do not trust the very resources you are citing.
Failing to tag paid links. If Google identifies paid dofollow links on your site, both the linking and receiving sites can face manual penalties. This is especially relevant for Singapore businesses that participate in sponsored content arrangements with bloggers, influencers, or media outlets. Always mark paid placements with the sponsored or nofollow attribute.
Obsessing over converting nofollow links to dofollow. Do not waste time contacting site owners asking them to remove the nofollow attribute from their links to your site. Most will ignore the request, and the time is better spent earning new links. If a major publication links to you with nofollow, that link is still delivering value through traffic, brand awareness, and discovery.
Disavowing nofollow links in Google Search Console. The disavow tool is for genuinely toxic dofollow backlinks from spammy or malicious domains, not for standard nofollow links from legitimate platforms. Submitting nofollow links to the disavow tool wastes your time and potentially confuses Google about your intentions.
How Nofollow Links Fit Into a Complete Link Strategy
A mature link-building strategy does not distinguish between “worth pursuing” and “not worth pursuing” based solely on whether a link is dofollow or nofollow. Instead, it evaluates every link opportunity based on its total business value: traffic potential, brand exposure, audience relevance, and SEO impact combined.
In practice, this means actively pursuing nofollow opportunities that put your brand in front of the right audience. Guest appearances on podcasts, contributions to LinkedIn articles, participation in Reddit Singapore or HardwareZone discussions, and social media engagement all generate nofollow links that serve your business goals.
It also means that your dofollow link-building efforts should focus on earning the highest-quality editorial links possible, because those carry the most direct ranking impact. Understanding how dofollow links function as a ranking factor helps you prioritise your outreach effectively.
The most successful SEO campaigns we run at Best Marketing integrate both dofollow and nofollow link acquisition into a unified strategy. The nofollow activities build brand visibility and create discovery opportunities. The dofollow activities translate that visibility into ranking authority. Together, they create a flywheel where each type of link reinforces the other.

Frequently Asked Questions
- Should I disavow nofollow links in Google Search Console?
-
No. Nofollow links do not pass negative signals to your site, so there is no reason to disavow them. The disavow tool should only be used for genuinely toxic dofollow links from spammy or malicious domains that could actively harm your rankings.
- Do nofollow links help with Google indexing?
-
Since 2019, Google treats nofollow as a hint for crawling and indexing purposes. This means a nofollow link from a well-crawled, high-authority site may help Google discover your pages faster, though it is not guaranteed. It is one more reason why nofollow links from major platforms still carry value.
- What is the difference between nofollow, sponsored, and ugc attributes?
-
Nofollow is the general-purpose attribute for any link you do not want to fully endorse. Sponsored is specifically for paid or advertised links where a commercial relationship exists. UGC is for links within user-generated content like comments and forum posts. All three signal to Google that link equity should not be passed freely, but the specific attribute gives Google additional context about the nature of the link.
- Can a nofollow link still drive traffic to my website?
-
Absolutely. The nofollow attribute only affects how search engines treat the link. Human users can click nofollow links exactly the same as dofollow links. A nofollow link on a high-traffic website can drive hundreds or thousands of visitors to your pages, and that traffic can convert into leads and revenue just as effectively as traffic from any other source.
- Do I need nofollow links in my backlink profile?
-
Yes. A natural backlink profile contains a healthy mix of dofollow and nofollow links because that is how links naturally occur on the web. A profile with only dofollow links looks artificially constructed. Most healthy profiles have roughly 60 to 80 percent dofollow and 20 to 40 percent nofollow links.
