Backlinks, also known as inbound links, are links from one website to another. In the world of SEO, they act like votes of confidence, signaling to search engines that your content is valuable and trustworthy. When reputable sites link to your pages, it helps improve your site's authority and visibility in search engine results.
Backlinks are a critical factor in how search engines determine the relevance and authority of your website. The more high-quality backlinks you have, the more likely your site will rank higher for relevant search queries. They not only drive referral traffic but also help build your site's credibility, making it easier to compete in crowded online spaces.
Backlinks come in two main types: DoFollow and NoFollow. DoFollow backlinks pass on "link juice," meaning they contribute to your site's SEO by boosting its authority and ranking potential. On the other hand, NoFollow backlinks include a special attribute that tells search engines not to pass SEO value through the link. While NoFollow links don't directly improve rankings, they still play a role in a natural link profile and can drive traffic and brand exposure.
Understanding the balance between these two types of backlinks is essential for effective link building strategies. Both have their place in a well-rounded SEO approach, helping your website grow its presence and authority over time.

Backlinks are essentially links from one website to another, serving as endorsements or votes of confidence in the digital world. Their primary purpose is to guide users to related or valuable content, but they also play a crucial role in SEO by signaling to search engines that a website is credible and authoritative. When multiple reputable sites link to your content, it suggests that your site offers valuable information worth referencing.
Search engines like Google use backlinks as a key factor in their ranking algorithms. They interpret backlinks as indicators of trustworthiness and relevance. The quality, quantity, and context of backlinks help search engines determine how authoritative a website is within its niche. For example, a backlink from a well-established, high-authority site carries more weight than one from a lesser-known or unrelated site. This evaluation helps search engines decide which pages to rank higher in search results.
While DoFollow and NoFollow are the most commonly discussed backlink types, there are other variations that influence SEO differently. For instance, UGC (User Generated Content) links are used to identify links within user-generated content like comments or forums, signaling a different level of trust. Sponsored links indicate paid placements and are treated distinctly by search engines to prevent manipulation. Understanding these different link attributes helps create a more natural and diverse backlink profile, which is beneficial for long-term SEO success.
Building a well-rounded backlink strategy means recognizing the variety of link types and how they contribute to your site's overall authority and visibility in search engines.
DoFollow backlinks are the standard type of links on the web that allow search engines to follow them and pass on SEO value from one site to another. When a website links to your page with a DoFollow link, it essentially endorses your content, signaling to search engines that your site is trustworthy and relevant. This endorsement helps improve your site's authority and can positively influence your search engine rankings.
The key benefit of DoFollow backlinks is their ability to transfer "link equity" or "link juice." This means that the SEO value from the linking site is passed along to your site, boosting your domain authority and helping your pages rank higher in search results. The more high-quality DoFollow backlinks you earn, especially from authoritative and relevant websites, the stronger your SEO profile becomes. This is why link building strategies often focus heavily on acquiring DoFollow links.

NoFollow backlinks are links that include a special HTML attribute (rel="nofollow") which instructs search engines not to pass SEO value or "link juice" to the linked site. This attribute was introduced to combat spam and prevent manipulative link-building practices. Essentially, NoFollow links tell search engines, "Don’t count this link as a vote of confidence." While they don’t directly boost your site’s ranking, they still play an important role in a natural backlink profile.
Unlike DoFollow links, NoFollow backlinks do not transfer authority or ranking power from the linking site to the linked site. This means they don’t contribute to your domain authority or search rankings in the traditional sense. However, search engines may still crawl these links and discover new content, which can indirectly benefit your SEO. Additionally, NoFollow links help diversify your backlink profile, making it look more organic and less manipulative to search engines.
NoFollow links are commonly found in areas prone to spam or paid placements. For example, links in blog comments, forums, and user-generated content often carry the NoFollow attribute to prevent spammy link building. Paid links and advertisements are also marked as NoFollow to comply with search engine guidelines and avoid penalties. Social media platforms typically use NoFollow links as well, since they want to allow sharing without passing SEO value. Understanding when and where NoFollow links appear helps you build a balanced link strategy that supports both SEO and user engagement.
DoFollow backlinks are the powerhouse behind SEO authority. When a reputable site links to your content with a DoFollow link, it’s like a vote of confidence that search engines count heavily. These links pass on "link juice," boosting your domain authority and helping your pages climb higher in search results. The more quality DoFollow backlinks you accumulate, especially from sites relevant to your niche, the stronger your SEO profile becomes. This is why many link-building strategies prioritize earning DoFollow links—they directly influence your site’s ability to rank well.
NoFollow backlinks might not pass SEO value directly, but they’re crucial for a balanced and natural backlink profile. Search engines look for diversity in your links to ensure your site isn’t manipulating rankings. Having a mix of NoFollow and DoFollow links signals authenticity and helps avoid penalties. Plus, NoFollow links can still drive referral traffic and increase brand visibility, which indirectly supports your SEO efforts by expanding your audience and potential for engagement.
While NoFollow links were originally designed to prevent passing SEO value, modern search engines have evolved. Google, for example, treats NoFollow as a hint rather than a strict directive, meaning it may choose to crawl and even consider these links in ranking decisions under certain circumstances. This shift encourages a more natural link ecosystem and rewards genuine linking behavior. So, while NoFollow links don’t guarantee SEO juice, they’re far from useless—they contribute to discovery, traffic, and a credible backlink profile that search engines appreciate.

DoFollow links are your primary tool for boosting SEO because they pass valuable link equity to your site. Focus on earning DoFollow backlinks from authoritative, relevant websites within your niche. Guest posting on reputable blogs, securing mentions in industry publications, and building partnerships with trusted sites are effective ways to gain these links. Always prioritize quality over quantity—one high-authority DoFollow link can be more beneficial than dozens of low-quality ones.
NoFollow links play a crucial role in maintaining a natural backlink profile and preventing penalties from search engines. Use NoFollow links when linking to untrusted or user-generated content, such as blog comments, forums, or paid advertisements. They are also essential for social media links and sponsored content to comply with search engine guidelines. While they don’t pass SEO value directly, NoFollow links can still drive traffic and increase brand exposure.
A healthy backlink profile includes a mix of both DoFollow and NoFollow links. Search engines expect diversity in link types to ensure your link-building efforts are organic and not manipulative. Overloading your site with only DoFollow links can raise red flags, while a natural balance signals authenticity. Aim for a varied backlink profile that includes DoFollow links for SEO authority and NoFollow links for traffic, brand visibility, and credibility. This balanced approach supports sustainable SEO growth over time.
To identify whether a backlink is DoFollow or NoFollow, you can use several handy tools and methods. Browser extensions like MozBar, Ahrefs SEO Toolbar, or the SEOquake plugin highlight link attributes directly on the page, making it easy to spot NoFollow links. Additionally, inspecting the HTML code of a webpage manually is straightforward: right-click the link, select "Inspect," and look for the rel attribute in the anchor tag.
The rel attribute in an anchor (<a>) tag defines the relationship between the linking page and the linked page. A NoFollow link explicitly includes rel="nofollow", signaling search engines not to pass SEO value. Conversely, DoFollow links either omit this attribute or use rel="dofollow" (though the latter is less common and not officially required). Essentially, if the rel attribute is missing or doesn’t include "nofollow," the link is treated as DoFollow by default.
Regularly auditing your backlink profile is crucial for SEO health. Use tools like Google Search Console, Ahrefs, or SEMrush to track your backlinks and their attributes. These platforms provide detailed reports showing which links are DoFollow or NoFollow, helping you maintain a balanced and natural link profile. Monitoring also helps identify potentially harmful links that could affect your rankings. Keeping an eye on link attributes ensures your link-building strategy stays effective and aligned with SEO best practices.
Building quality DoFollow backlinks requires a strategic approach focused on creating value and fostering genuine relationships. Guest posting on reputable blogs within your industry is a proven way to earn DoFollow links, as it allows you to showcase your expertise while gaining authoritative backlinks. Forming partnerships with complementary businesses or influencers can also lead to natural DoFollow links through collaborations, joint content, or resource sharing. Content marketing remains a cornerstone—producing high-quality, shareable content like in-depth guides, infographics, or original research attracts organic DoFollow backlinks from sites that find your content valuable.
While NoFollow links don’t pass SEO authority, they shouldn’t be overlooked. These links often appear on social media platforms, forums, and popular blogs, driving targeted referral traffic and increasing brand visibility. Engaging actively in communities and contributing valuable insights can earn NoFollow links that boost your brand’s reach and credibility. This exposure can lead to more organic DoFollow backlinks over time as your brand gains recognition.
It’s crucial to steer clear of black-hat SEO tactics like buying links, participating in link farms, or using automated link-building tools. These practices can lead to penalties from search engines, harming your site’s ranking and reputation. Instead, focus on earning backlinks naturally through quality content and authentic relationships. A balanced backlink profile with a mix of DoFollow and NoFollow links signals to search engines that your link-building efforts are legitimate and sustainable.
By combining these strategies, you can build a robust backlink profile that supports long-term SEO success and drives meaningful traffic to your site.
A healthy SEO strategy includes a mix of both DoFollow and NoFollow backlinks. Relying solely on DoFollow links can look unnatural to search engines and raise red flags, while a diverse backlink profile signals authenticity and trustworthiness. NoFollow links help diversify your link profile, improve brand visibility, and attract referral traffic, indirectly supporting SEO growth.
For businesses aiming to grow their online presence, like those using GrowPilot’s automated content and SEO tools, understanding and balancing these backlink types is crucial. By focusing on earning high-quality DoFollow backlinks while maintaining a steady flow of NoFollow links, you create a robust, natural backlink profile that search engines favor. This balanced approach not only improves rankings but also drives sustainable, long-term organic growth.
