What Are Nofollow Links? Understanding the Basics
At their core, nofollow links contain a simple HTML attribute that instructs search engines like Google not to pass authority (often called “link juice”) from one page to another. They look like this in the HTML code:
<a href="https://www.example.com" rel="nofollow">Example Website</a>That small rel="nofollow" addition makes a significant difference in how search engines crawl and evaluate your website’s link structure.
When Google’s crawlers encounter a nofollow link, they essentially see a sign that says, “Don’t follow this path or count this as an endorsement.” This differs dramatically from standard links (sometimes called “dofollow” links), which pass authority and act as “votes of confidence” from one page to another.
| Link Type | How It Works | SEO Impact | When To Use |
|---|---|---|---|
| Nofollow | Contains rel=”nofollow” attribute | Doesn’t pass authority or PageRank | Paid links, user-generated content, untrusted sources |
| Dofollow | Standard link without special attributes | Passes authority and contributes to link equity | Trusted sources, editorial links, internal linking |

The Evolution of the Nofollow Attribute: From Spam Fighter to Nuanced Signal
The nofollow attribute wasn’t always part of the SEO landscape. Google introduced it in 2005 primarily as a weapon against comment spam. Blog owners were drowning in spammy comments containing links intended to manipulate search rankings, and the nofollow tag gave webmasters a way to allow comments without passing SEO value.
Since then, the nofollow attribute has evolved significantly:
- 2005: Initial introduction focused solely on fighting comment spam
- 2009-2013: Google expanded recommendations to include using nofollow for advertising links
- 2019: Major update introducing two new link attributes: rel=”sponsored” and rel=”ugc” to provide more granular signals
The 2019 update marked a pivotal shift in how Google treats nofollow links. Prior to this, Google would not count nofollow links for ranking purposes at all. Now, Google treats these attributes as “hints” rather than directives, meaning they may choose to use nofollow links as ranking signals in certain contexts.
| Era | Nofollow Treatment | SEO Implications |
|---|---|---|
| 2005-2019 | Strict directive: no PageRank or authority passed | Nofollow links provided zero direct SEO benefit |
| 2019-Present | Treated as a “hint” rather than absolute directive | Potential for some ranking influence in specific contexts |
Nofollow vs. Dofollow Links: Understanding the Critical Difference
The fundamental difference between these link types lies in how they transfer authority between websites. Think of dofollow links as explicit endorsements that pass SEO equity, while nofollow links are more like neutral mentions that don’t pass that voting power.
How to Identify Nofollow Links
You can’t visually distinguish between nofollow and dofollow links just by looking at a webpage. They appear identical to users. To identify nofollow links, you need to:
- Right-click on the link and select “Inspect” or “Inspect Element” in your browser
- Look for the
rel="nofollow"attribute in the HTML code - Alternatively, use SEO tools like Ahrefs, SEMrush, or Moz to analyze backlinks
| Feature | Dofollow Links | Nofollow Links |
|---|---|---|
| Default Setting | Yes (all links are dofollow unless specified) | No (requires adding the rel attribute) |
| Passes Link Equity | Yes | Generally no |
| Impact on Rankings | Direct positive influence | Limited indirect influence |
| Google Crawling | Always followed | May be crawled but typically not counted for ranking |

When to Use Nofollow Links: Best Practices for Responsible SEO
Implementing nofollow links correctly is crucial for maintaining a healthy website and avoiding Google penalties. Here are the primary scenarios where you should use the nofollow attribute:
Paid Links and Advertisements
Any link that’s been purchased or is part of a paid arrangement must use nofollow (or the newer sponsored attribute). Google’s guidelines are explicit: passing authority through paid links violates their webmaster guidelines and can result in penalties.
User-Generated Content
Links in comments, forums, and other user-generated content should typically be nofollowed because:
- You can’t vouch for the quality of every site users link to
- It prevents spam commenters from exploiting your site for SEO gains
- It protects you from being associated with potentially low-quality or spammy websites
Untrusted Content Sources
When linking to sites you don’t fully trust or endorse, using nofollow protects your site’s reputation with search engines.
Login Pages and Non-Index Pages
Internal links to pages that serve utility functions rather than content purposes can benefit from nofollow attributes to better direct your site’s authority flow.
| Scenario | Why Use Nofollow | Potential Risk of Not Using Nofollow |
|---|---|---|
| Paid Links | Required by Google’s guidelines | Manual penalties, ranking drops, deindexing |
| Comment Sections | Prevents spam and protects your site’s authority | Authority dilution, association with low-quality sites |
| Widget Links | Widgets distributed across many sites need nofollow | Potential for Google to view as manipulative linking |
| Press Releases | Often considered commercial in nature | Could be viewed as unnatural link building |
Understanding Other Rel Attributes: A Comprehensive Guide
In 2019, Google expanded the link attribute ecosystem beyond just nofollow, introducing more specific options for webmasters to provide context about different types of links:
Rel=”sponsored”
This attribute is specifically designed for advertisements, sponsorships, and other paid placements. While nofollow still works for these cases, rel=”sponsored” provides more precise signals to Google about the nature of the link.
Rel=”ugc”
Standing for “User Generated Content,” this attribute is ideal for links within comments, forums, and other user-contributed sections of your website.
You can also combine these attributes when appropriate, like rel="nofollow sponsored" for paid links.
| Attribute | Primary Use Case | Implementation Example |
|---|---|---|
| rel=”nofollow” | General purpose when you don’t want to pass authority | <a href="example.com" rel="nofollow">Example</a> |
| rel=”sponsored” | Paid arrangements, advertisements, sponsorships | <a href="example.com" rel="sponsored">Example</a> |
| rel=”ugc” | User generated content like comments and forum posts | <a href="example.com" rel="ugc">Example</a> |

The Hidden Benefits of Nofollow Links: Why They Still Matter
Despite not passing authority in the traditional sense, nofollow links offer several significant benefits that make them valuable components of a comprehensive SEO strategy:
Traffic Generation
A nofollow link on a high-traffic website can drive substantial referral traffic. Users don’t see or care about the nofollow attribute; they simply click links that interest them. This direct traffic benefit exists completely independent of SEO value.
Brand Visibility and Recognition
Appearing on prominent websites, even with nofollow links, increases brand exposure. This visibility contributes to:
- Improved brand recognition
- Greater consumer trust
- Increased likelihood of earning additional mentions (including dofollow links)
Natural Link Profile Diversity
A natural backlink profile contains a healthy mix of both dofollow and nofollow links. A link profile consisting of 100% dofollow links actually appears suspicious to search engines and may trigger manual reviews.
Potential Indirect SEO Benefits
With Google’s 2019 update treating nofollow as a “hint” rather than a directive, some nofollow links may provide ranking benefits in certain contexts. Additionally, these links can lead to discovery of your content, potentially resulting in additional dofollow links.
| Benefit Type | How Nofollow Links Provide Value | Measurement Methods |
|---|---|---|
| Direct Traffic | Users click through regardless of rel attribute | Google Analytics referral traffic reports |
| Brand Building | Increases mentions and visibility | Brand mention tracking, share of voice metrics |
| Discovery Potential | Leads to content discovery by others who may link | New backlink acquisition after nofollow placements |
| Profile Naturalness | Creates a diverse, natural-looking backlink profile | Link profile analysis tools showing link attribute ratios |
Building a Balanced Link Strategy: Integrating Dofollow and Nofollow
The most effective link building strategies embrace both dofollow and nofollow links as complementary elements rather than focusing exclusively on authority-passing links.
Creating a Natural Link Profile
A natural backlink profile typically contains:
- Approximately 60-70% dofollow links
- About 30-40% nofollow links
- A variety of anchor texts, both branded and keyword-focused
- Links from diverse domains across different authority levels
Strategic Prioritization in Link Building
While you shouldn’t turn down nofollow opportunities, it makes sense to prioritize your active link building efforts:
- Tier 1 Priority: High-authority, relevant dofollow links
- Tier 2 Priority: High-traffic websites with nofollow links
- Tier 3 Priority: Lower-authority dofollow opportunities
- Tier 4 Priority: Low-traffic, low-authority nofollow links
Internal Linking Considerations
Your internal linking strategy should also incorporate strategic use of nofollow attributes:
- Use dofollow for links to your most important content
- Consider nofollow for utility pages like login pages, terms of service, etc.
- Master strategic internal linking to distribute authority throughout your site
| Link Building Activity | Dofollow Potential | Nofollow Reality | Strategic Value |
|---|---|---|---|
| Guest Posting | Medium | Increasingly nofollow on many sites | High (traffic + exposure) |
| HARO/Journalist Outreach | High | Usually dofollow, some major publications use nofollow | Very High (authority + credibility) |
| Social Media Profiles | None | Almost always nofollow | Medium (traffic + brand presence) |
| Industry Directories | Medium | Mixed results | Medium (relevance + citations) |

Analyzing Your Link Profile: Tools and Techniques
Regular auditing of your backlink profile helps ensure you maintain a natural mix of dofollow and nofollow links while identifying potential issues before they impact your rankings.
Essential Link Analysis Tools
Several professional tools can provide detailed insights into your link profile:
- Ahrefs: Comprehensive backlink analysis with link type filtering
- SEMrush: Detailed backlink analytics with toxic link identification
- Moz Link Explorer: Link profiling with spam score assessment
- Google Search Console: Basic link reporting directly from Google
What to Look For in Your Link Analysis
When reviewing your backlink profile, pay special attention to:
- The ratio between dofollow and nofollow links
- Anchor text distribution (overly optimized anchor text can trigger penalties)
- Link velocity and patterns (sudden spikes may look unnatural)
- The quality and relevance of linking domains
Addressing Link Profile Issues
If your analysis reveals problems, consider these remediation tactics:
- For too many dofollow links from questionable sources: Use Google’s disavow tool
- For an unnaturally high percentage of dofollow links: Incorporate more legitimate nofollow link building into your strategy
- For over-optimized anchor text: Focus on earning more branded and natural anchor text links
| Analysis Metric | Healthy Profile Indicator | Warning Sign |
|---|---|---|
| Dofollow to Nofollow Ratio | 60-70% dofollow, 30-40% nofollow | 90%+ dofollow or 90%+ nofollow |
| Anchor Text Distribution | Primarily branded, with some topical and naked URLs | Excessive exact-match keyword anchors |
| Link Growth Pattern | Steady, organic growth over time | Sudden large spikes in short timeframes |
| Referring Domain Quality | Mix of authority levels with topical relevance | Many links from low-quality or topically irrelevant sites |
Frequently Asked Questions About Nofollow Links
Are nofollow links completely worthless for SEO?
No, nofollow links are not worthless. While they typically don’t pass direct authority, they provide brand visibility, drive referral traffic, create a natural link profile, and can indirectly lead to dofollow links through increased exposure. Since Google’s 2019 update, they may even provide ranking signals in some contexts.
Do social media links help SEO despite being nofollow?
Yes, social media links help SEO in indirect ways. They increase content visibility, drive traffic, build brand awareness, and can lead to additional linking opportunities from people who discover your content through social channels. While the links themselves are typically nofollow, the secondary effects can be substantial.
Will using nofollow inappropriately hurt my website?
Using nofollow inappropriately (like on your internal links without good reason) can prevent optimal flow of authority throughout your site. However, the bigger risk comes from NOT using nofollow when you should, particularly for paid links, which can result in Google penalties.
How can I tell if a link to my site is nofollow?
You can identify nofollow links by inspecting the HTML code (right-click and select “Inspect” or “View Page Source”), then looking for the rel=”nofollow” attribute. Alternatively, various SEO tools like Ahrefs, SEMrush, and Moz will identify nofollow links in their backlink reports.
Should I ask sites to remove their nofollow attribute from links to my content?
Generally, this isn’t recommended. Many websites have policies about using nofollow links, especially for guest posts or contributed content. Repeatedly asking sites to remove nofollow attributes can harm relationships and rarely succeeds. Instead, focus on creating exceptional content that naturally earns dofollow links and appreciate nofollow links for their other benefits.
Take Your Link Building Strategy to the Next Level
