What are No-follow Links?

In the dynamic world of digital marketing, Search Engine Optimization (SEO) is a pivotal tool for enhancing online visibility and audience engagement. SEO refers to the strategic practice of optimizing a website to increase its ranking in search engine results, thereby attracting more organic traffic. This process is crucial in an era where the majority of online experiences begin with a search engine. Among the many tactics employed in SEO, the use of links, particularly "no-follow links,” plays a significant role.

But what are no-follow links? Why is it important? And how can you take advantage of it to improve your online presence? This post answers these questions and more, as it takes you through a complete guide on no-follow links.

No-follow Links

What are No-follow Links?

No-follow links are a specific type of hyperlink that plays a unique role in the world of SEO and web navigation. These links have an attribute that tells search engines to ignore them when assessing the link equity and authority of web pages. This attribute effectively separates no-follow links from the standard or "do-follow" links in terms of their impact on SEO. Below are the common use cases of no-follow links:

Uses of No-follow Links

1. Non-Endorsement Indicator

No-follow links are used when a website wants to provide a link to another page without passing on authority or endorsement. This is particularly useful in cases where a site cannot vouch for the complete credibility of the content it links to, such as user-generated content, comments, or sponsored links.

2. Spam Prevention

Originally introduced to combat spam, the no-follow attribute helps webmasters prevent search engines from associating their sites with potentially untrustworthy or low-quality content. By using no-follow links in comment sections or forums, websites can deter spammers who might seek to benefit from the site's authority.

3. Control Over Link Equity

No-follow links allow website owners to control the flow of link equity. This means they can link to external content for informational purposes without influencing the search engine ranking of the linked page.

Technical Perspective: Using No-Follow Attributes in HTML

  • TML Syntax: In HTML, the no-follow attribute is implemented by adding rel="nofollow" to the anchor tag (<a>) of a hyperlink. For example, <a href="" rel="nofollow">Link</a>.

  • Search Engine Interpretation: When a search engine crawls a website and encounters a no-follow link, it understands that the link should not influence the ranking of the link's target in the search engine's index. This is not an instruction to the search engine not to crawl or index the linked page, but rather a directive not to consider the link as a factor in ranking algorithms.

  • Variations and Updates: Over time, search engines have introduced variations to the no-follow attribute, such as rel="sponsored" and rel="ugc" (user-generated content), to provide more granularity. However, rel="nofollow" remains a widely used attribute for controlling link equity distribution.

No-follow links undoubtedly serve as a crucial tool for website owners and SEO practitioners, offering a way to link to external content without directly influencing search engine rankings. Understanding and correctly implementing the no-follow attribute is a key aspect of effective SEO and website management. But have you ever wondered about the history behind this link attribute?

History and Origin of No-follow Links

The no-follow attribute was introduced as a collaborative effort by major search engines to address specific issues related to the quality and integrity of linking practices on the internet. This initiative marked a significant development in the world of SEO and web navigation.

Introduction of the No-follow Attribute

The no-follow attribute was introduced in 2005 as a joint effort by Google, Microsoft (Bing), and Yahoo. This collaboration was a response to the growing concerns over link spam and the need for better control mechanisms in the SEO landscape.

Its initial purpose was to provide webmasters with a tool to combat comment spam on blogs and forums. Before its introduction, spammers frequently exploited comment sections to insert links to their websites, artificially inflating their site’s search engine rankings by leveraging the host site's authority.

This posed a significant challenge to the quality of search results. Search engines relied heavily on links to determine the authority and relevance of websites. Spammers exploited this by creating irrelevant or deceptive links to manipulate search rankings.

The integrity of linking practices was crucial for search engines to maintain reliable and relevant search results. The no-follow attribute provided a means for website owners to link to external content without endorsing it, thereby preserving the quality of their link profile.

For website owners, the ability to designate links as no-follow helped protect their sites from being associated with low-quality or untrustworthy content. This was particularly important for maintaining the site’s credibility both with users and search engines.

The no-follow attribute, thus contributed to a more trustworthy and user-friendly internet, where users could be more confident in the quality and relevance of the content they found through search engines.

In summary, the introduction of the no-follow link attribute was a significant milestone in the evolution of SEO. It provided a necessary tool for combating link spam, controlling link quality, and maintaining the integrity of search engine results. This innovation has had a lasting impact on how links are used and perceived in the digital space, underscoring the ongoing effort to balance effective SEO practices with the need for high-quality, trustworthy content on the web.

If you’re familiar with SEO, though, you know that “no-follow” is not the only link attribute out there. The do-follow link is another attribute with a different purpose. What are the differences between these link attributes?

Comparing No-follow and Do-follow Links

Understanding the differences between no-follow and do-follow links is crucial in the realm of SEO, as each type of link has distinct characteristics and impacts on a website's ranking and overall search engine performance. Below are the key differences between no-follow and do-follow Links:

1. Link Equity Passage

The most significant difference lies in how they pass link equity (often referred to as "link juice"). Do-follow links are standard links that pass on link equity from one site to another, contributing to the receiving site’s search engine ranking. In contrast, no-follow links have a rel="nofollow" attribute that signals search engines not to pass on link equity.

2. Search Engine Crawling and Indexing

While both link types can be crawled and indexed by search engines, only do-follow links influence the ranking algorithm directly. No-follow links tell search engines not to count the link in their ranking calculations, although the content at the linked URL can still be indexed.

3. Usage Context

Do-follow links are typically used when linking to trustworthy, relevant content. No-follow links are often employed in contexts where the site cannot vouch for the linked content’s credibility, such as user-generated comments, sponsored posts, or external links that might not be entirely relevant to the content.

4. Impact on SEO and Website Ranking

  • Do-Follow Links: These are powerful tools in SEO as they directly contribute to the website's domain authority and ranking. A site with a high number of quality do-follow backlinks from reputable sources is likely to rank higher in search engine results, as these links are considered endorsements of the site's content.

  • No-Follow Links: Initially, no-follow links were thought to have no impact on SEO. However, over time, their role has been reevaluated. While they don’t pass link equity in the traditional sense, they can indirectly benefit SEO by:

  • Driving traffic: No-follow links from high-traffic websites can lead to increased site visits.

  • Enhancing site visibility: Being featured on reputable sites, even without link equity, can raise a site's profile and credibility.

  • Diversifying the link profile: A natural mix of do-follow and no-follow links can make a site's link profile appear more organic and less manipulative to search engines.

All in all, both no-follow and do-follow links are integral to a well-rounded SEO strategy. Do-follow links directly influence search engine rankings by passing link equity, while no-follow links, despite not passing this equity, play a vital role in driving traffic, enhancing visibility, and ensuring a natural and credible link profile.

With that in mind, how can you effectively make use of the "no-follow" link attribute?

Best Practices for Using No-follow Links

Using no-follow links effectively is about understanding their role in your overall SEO strategy and ensuring compliance with legal and search engine guidelines. Here are some tips on how to use no-follow links:

1. Maintain a Natural Link Profile

Incorporate a mix of do-follow and no-follow links to make your site's link profile appear more natural and less manipulative to search engines.

2. Use of Unverified or Paid Links

Apply no-follow tags on links that are either unverified, user-generated or part of paid agreements (like advertisements or sponsored content).

3. Focus on Relevance and Quality

Even for no-follow links, prioritize linking to content that is relevant and valuable to your audience.

Legal Considerations and Adherence to Search Engine Guidelines

  • Comply with Search Engine Policies: Following the guidelines set by major search engines like Google is crucial to avoid penalties. This includes properly tagging sponsored content and advertisements with no-follow attributes.

  • Transparency in Sponsored Links: Legally, it’s important to disclose sponsored links or content to maintain transparency with your audience, which aligns with the ethical practices in digital marketing.

Impact of No-follow Links on SEO

The impact of no-follow links on SEO has been a topic of discussion and sometimes misconceptions within the digital marketing community. Understanding the current perspective on no-follow links is crucial for effective SEO strategies.

Exploring Common Misconceptions About No-follow Links and SEO

  • No-follow Links Have No SEO Value: One prevalent misconception is that no-follow links offer no SEO benefit whatsoever. While it's true that they don't pass link equity in the traditional sense, they can still contribute to a website's overall profile and drive traffic, which are indirect SEO benefits.

  • No-follow Links are Bad: Some people mistakenly believe that no-follow links are harmful to a website's SEO. In reality, a natural link profile includes a mix of both no-follow and do-follow links, and having no-follow links can signal to search engines that your link profile is organic and not manipulative.

Current Understanding of How Search Engines Treat No-follow Links

Not Passing Link Equity: Generally, no-follow links do not pass link equity (or "link juice"), meaning they do not directly influence the search engine ranking of the linked page.

Potential for Indirect SEO Benefits: Search engines have evolved to understand the web's complexity better. No-follow links from high-traffic, reputable sources can lead to increased visibility and indirect SEO benefits like driving traffic.

Crawling and Indexing: No-follow links can still be crawled and indexed by search engines, meaning the content at the linked URL is acknowledged, even if the link itself doesn’t pass authority.

The Future of No-follow Links

The landscape of SEO is ever-evolving, and the role and interpretation of no-follow links continue to adapt to these changes. Recent updates and expert insights suggest an interesting future for how no-follow links are viewed and utilized in SEO and link-building strategies.

Recent Updates in Search Engine Views on No-follow Links:

  • Evolution in Interpretation: Search engines like Google have started to view no-follow links more as "hints" rather than strict directives. This means that while no-follow links are generally not considered for passing link equity, search engines might choose to consider them in certain contexts, particularly when assessing the overall link profile of a site.

  • Introduction of New Link Attributes: Google has introduced additional link attributes such as rel="sponsored" for paid or sponsored links and rel="ugc" for user-generated content. This allows for a more nuanced interpretation of links by search engines.

Predictions and Expert Insights on Future Trends:

  • Increased Emphasis on Link Quality Over Type: The future of SEO may see a diminished emphasis on whether a link is no-follow or do-follow. Instead, the focus might shift more toward the quality, relevance, and context of the linking site and linked content.

  • AI and Machine Learning: With advancements in AI and machine learning, search engines may become more adept at understanding the intent and context of links, further refining how they interpret no-follow links.

  • Holistic Evaluation of Websites: Experts predict a more holistic approach to evaluating websites, where the overall content quality, user experience, and authenticity play a more significant role than mere link types.


In conclusion, no-follow links have evolved from being mere tools to combat spam to becoming integral parts of complex SEO strategies. The key points to remember are:

➔    Role in SEO: No-follow links were introduced to combat spam and manage link quality, ensuring the integrity of search engine rankings.

➔    Impact: While they don't directly pass link equity, no-follow links contribute to a site's SEO indirectly through traffic generation and by signaling a natural, balanced link profile.

➔    Best Practices: Using no-follow links appropriately involves understanding when they're necessary (such as in user-generated content or sponsored links) and adhering to search engine guidelines.

➔    Future Outlook: The future of no-follow links points towards a more nuanced approach by search engines, considering the broader context and quality of links rather than just their no-follow or do-follow status.

No-follow links, thus, continue to play a vital role in SEO strategies. They are not just tools for negating undesirable link equity but are part of a broader, more nuanced approach to building a credible, authoritative, and user-focused online presence. As search engines evolve, so will the strategies around no-follow links, underscoring the importance of staying informed and adaptable in the dynamic world of SEO.
