What Is a Dofollow/Nofollow Link in SEO?

A dofollow/nofollow link in SEO refers to whether a hyperlink passes ranking authority from one website to another or not. A dofollow link is the default type of link on the web and tells search engines to follow it and pass along some of the linking site’s trust and authority. A nofollow link carries a special attribute in the code that tells search engines not to pass that authority through. Understanding a dofollow/nofollow link in SEO matters because it directly affects how backlinks contribute to your rankings, and getting the balance wrong in either direction can quietly hold back an otherwise solid SEO effort.

This guide breaks down both link types in depth, how link juice actually moves between pages, where link insertion and deep linking fit into the picture, and how to build a backlink profile that looks genuinely natural to search engines rather than manipulated.

Why Dofollow and Nofollow Links Exist in the First Place

Before Google introduced the nofollow attribute in 2005, link building was far easier to abuse. Anyone could drop a link into a blog comment, forum signature, or guestbook, and that link would pass authority to whatever page it pointed to, regardless of relevance or quality. This created a flood of low value, spammy links purely built to manipulate rankings rather than genuinely help readers find useful information.

The nofollow attribute solved a real, practical problem: it gave website owners and platforms a way to allow open commenting and user generated content without every single link inside that content passing ranking authority somewhere else. This is the root of the entire dofollow/nofollow link in SEO distinction, and understanding that history makes the modern rules make a lot more sense.

What Is a Dofollow Link in SEO

A dofollow link in SEO is simply a regular hyperlink with no restrictive attribute attached to it. There’s technically no such thing as rel=”dofollow” in HTML, since the absence of a nofollow, sponsored, or UGC tag is what makes a link “dofollow” by default.

When another website links to your page with a dofollow link, it shares a portion of its own authority with you, often called link juice. Search engines interpret this as a vote of confidence, and if the linking site is trustworthy and relevant to your niche, that vote carries real weight for your rankings.

It’s worth noting that not every dofollow link carries equal weight. A dofollow link from a well established, high authority site in your exact industry will typically do far more for your rankings than a dofollow link from a low quality, unrelated, or spammy website, even though both are technically the same link type from a code perspective.

Do Follow Links in SEO and Why They Matter

Do follow links in SEO are the foundation of most link building strategies, since they’re the only link type that directly contributes to your domain’s authority and search visibility. When you earn a do follow link from a reputable, topically relevant website, it signals to search engines that your content is worth trusting.

That said, quality matters far more than volume. A single do follow link from a well established, relevant website usually carries more weight than dozens of do follow links from low quality or unrelated sites. This is one of the more common misunderstandings business owners run into when evaluating an SEO company’s link building results, since a report showing “50 new backlinks this month” means very little without knowing the quality and relevance of where those links actually came from.

What Is No Follow in SEO

No follow in SEO is an HTML attribute, written as rel=”nofollow”, that tells search engines not to pass ranking authority through that particular link. Google introduced this attribute back in 2005 to help control spam in blog comments and forum posts, where people were dropping links purely to manipulate rankings.

A no follow link in SEO looks like this in code: an anchor tag with rel=”nofollow” added to it. Since 2019, Google has treated this attribute as a hint rather than an absolute rule, meaning it may still crawl and evaluate a nofollow link depending on context, even though it typically won’t pass authority through it.

That same 2019 update also introduced two additional related attributes worth knowing: rel=”sponsored” for paid links and advertisements, and rel=”ugc” for links found in user generated content like comments and forum posts. Both function similarly to nofollow in that they signal to search engines not to pass authority through, but they give Google more specific context about why the link exists, which helps its systems better distinguish between genuinely earned links and paid or user submitted ones.

What Is a No Follow Link in SEO Used For

A no follow link in SEO is commonly used in a few specific situations:

• Blog comments and forum posts, where anyone can drop a link
• Paid placements, sponsored posts, and affiliate links
• Links to sources you don’t want to vouch for or endorse
• Widget links or auto generated content sections
• Links within press releases, since Google explicitly recommends nofollow or sponsored tags here

Using nofollow in these cases protects your site from passing authority to spammy or irrelevant destinations, and it also keeps you compliant with search engine guidelines around paid and sponsored content. Businesses that skip this step on sponsored content or paid placements risk their site being viewed as participating in a link scheme, which can lead to a manual action from Google in more serious cases.

Do Follow SEO Strategy: Finding the Right Balance

A smart do follow SEO strategy isn’t about chasing dofollow links exclusively. A backlink profile made up entirely of dofollow links can actually look unnatural to search engines, since real websites earn a natural mix of both link types over time.

The healthiest approach combines steady dofollow link acquisition from relevant, trustworthy sources with a natural sprinkling of nofollow links from social shares, forums, and mentions. This mix signals organic growth rather than a manipulated link profile. This is the same balance a properly structured SEO strategy is built around, prioritizing relevant, earned dofollow links while still allowing nofollow mentions to occur naturally through social sharing and community engagement.

What Is Link Juice in SEO

Link juice is the informal term SEOs use to describe the authority, trust, and ranking value passed from one page to another through a link. When a page with strong authority links to your site using a dofollow link, some of that authority transfers over, which can help your page rank better for relevant searches.

Several factors affect how much link juice actually passes through a link, including the authority of the linking domain, the relevance of the linking page’s topic to yours, and how many other outbound links exist on that same page, since authority gets divided among all the links present. A page with two outbound links passes noticeably more weight through each one than a resource page listing two hundred outbound links, even if both pages have similar overall authority.

Anchor text also plays a role in how link juice gets interpreted. A link using descriptive, relevant anchor text, like “local SEO checklist” rather than a generic “click here,” gives search engines additional context about what the linked page is actually about, which strengthens the value of that particular link.

What Is Link Insertion in SEO

Link insertion in SEO is the practice of adding a link into an already published, existing piece of content rather than requiring a brand new article to be written for it. Instead of pitching a guest post, you find an already ranking page that’s relevant to your topic and request that a link to your site be inserted naturally into the existing text.

This approach has become popular because it’s often faster and more cost effective than traditional guest posting, though the same quality rules apply: the placement should feel natural, contextually relevant, and genuinely useful to a reader, not forced in purely for SEO purposes. Since the target page is already published and often already ranking, an inserted link can start contributing authority immediately rather than waiting for a brand new guest post to get indexed and gain its own traction first.

Guest Posting vs Link Insertion vs Digital PR

These three tactics all aim for the same outcome, earning relevant dofollow links, but they work quite differently in practice.

Guest posting involves writing an entirely new article for another website in exchange for a link back to your site, usually within the author bio or naturally within the body content.

Link insertion, as covered above, skips the content creation step entirely by adding a link into content that already exists and is already performing.

Digital PR takes a broader approach, creating genuinely newsworthy content, data studies, or original research that journalists and bloggers want to reference and link to on their own, without needing to be asked directly.

Most established link building programs use a mix of all three, since each has different cost, speed, and quality tradeoffs. Guest posting tends to build stronger topical relationships over time, link insertion delivers faster results at a lower cost, and digital PR can produce the highest authority links but requires genuinely compelling content and often a longer timeline to land coverage.

What Is Deep Linking in SEO

Deep linking in SEO refers to linking directly to a specific, deeper page on a website rather than always pointing to the homepage. For example, instead of linking to a company’s homepage, a deep link might point straight to a specific product page, blog post, or service page.

Deep linking helps distribute authority throughout a website rather than concentrating it all on the homepage, and it also helps search engines discover and understand the value of your inner pages more effectively. A healthy backlink profile typically includes a mix of homepage links and deep links pointing to relevant internal pages.

This principle applies just as much to internal linking as it does to backlinks from other sites. A blog post that only ever links back to a homepage wastes an opportunity to pass relevant authority to a more specific page, like a dedicated service page that’s actually trying to rank for a related, specific keyword.

Understanding Link Juice in SEO in Simple Terms

For anyone searching for a simpler explanation of link juice in SEO, think of it as a transfer of trust between websites. If a well respected, high authority site links to your page, it’s similar to a trusted expert publicly recommending your business. That recommendation carries weight, and search engines factor it into how they rank your content. The more relevant and reputable the source, the more that trust transfer actually helps.

This is also why a handful of genuinely relevant, high quality links usually outperforms a large volume of weak, unrelated ones. Ten thoughtful recommendations from respected people in your exact industry will always mean more than a hundred random mentions from strangers with no connection to what you actually do, and search engines evaluate backlinks with a very similar logic.

How to Build a Healthy Backlink Profile

Building a strong mix of dofollow and nofollow links doesn’t happen by accident, it usually follows a deliberate, ongoing process.

Start with genuinely link worthy content. Detailed guides, original data, and useful tools naturally attract links because people want to reference them, which removes much of the need for aggressive outreach in the first place.

Prioritize relevance over raw authority. A dofollow link from a moderately authoritative site in your exact niche is often more valuable than a link from a massive, unrelated site, since relevance is a major factor in how much weight a link actually carries.

Diversify your link sources. A backlink profile built entirely from one tactic, like only guest posts or only link insertions, tends to look less natural than one built from a genuine mix of guest content, digital PR, natural mentions, and the occasional nofollow link from social sharing.

Monitor your existing backlink profile regularly. Periodically reviewing your backlinks helps catch harmful, spammy links pointing at your site before they cause damage, and Google’s disavow tool exists specifically for addressing links you can’t get removed manually.

Pace link acquisition naturally. A sudden, unnatural spike in new backlinks, especially all arriving within a short window, can appear manipulative to search engines, whereas a steady, consistent flow over time looks like organic growth.

Common Mistakes With Dofollow and Nofollow Links

A few recurring mistakes show up often, even among businesses actively trying to do SEO correctly.

• Buying links in bulk from low quality, unrelated websites purely to increase dofollow link count
• Forgetting to add rel=”sponsored” or rel=”nofollow” to paid placements and sponsored content, risking a manual action
• Obsessing entirely over dofollow links while ignoring the value nofollow links bring in referral traffic and brand visibility
• Using the exact same anchor text across dozens of backlinks, which can look manipulative rather than natural
• Never auditing an existing backlink profile, allowing spammy or toxic links to accumulate unnoticed over time
• Concentrating all backlinks on the homepage instead of using deep linking to distribute authority to relevant inner pages

How to Check If a Link Is Dofollow or Nofollow

Checking whether a link is a dofollow/nofollow link in SEO terms is simple. Right click on the link in your browser, select inspect, and look at the HTML code. If you see rel=”nofollow” attached to the anchor tag, it’s a nofollow link. If no such attribute appears, it’s a dofollow link by default.

For checking your own site’s full backlink profile at scale, dedicated SEO tools can pull a complete list of every backlink pointing to your domain, along with whether each one is dofollow or nofollow, the authority of the linking domain, and the anchor text used. Reviewing this periodically is a far more reliable method than manually inspecting individual links one at a time.

How This Fits Into a Broader SEO Strategy

Dofollow and nofollow links are just one piece of a much larger picture. Off page factors like backlinks work alongside on page optimization, technical SEO, and content quality to determine how a site ranks overall. A site with an excellent backlink profile but poor technical health or thin content will still struggle, just as a technically flawless site with no backlinks at all will rarely compete for competitive search terms.

If you’re evaluating whether a provider actually understands this balance, it’s worth asking directly how they approach link building as part of a full strategy rather than treating it as an isolated task, a question covered in more depth in our guide on what to ask a SEO company before hiring them, since link building practices specifically are one of the more common areas where lower quality agencies cut corners.

Frequently Asked Questions

Can a nofollow link ever help my SEO?
Yes, indirectly. While it typically won’t pass ranking authority, a nofollow link can still drive referral traffic, increase brand visibility, and occasionally get crawled and considered by Google depending on context.

Is it bad to have nofollow links pointing to my site?
No, a natural mix of both link types is actually healthier than a backlink profile made up entirely of dofollow links, since real websites earn both kinds of links over time.

How many dofollow links do I need to rank well?
There’s no fixed number. Relevance and authority of each individual link matter far more than the total count, and a smaller number of genuinely strong links usually outperforms a large number of weak ones.

Should I nofollow all outbound links on my own website?
No, only links pointing to paid placements, untrusted sources, or user generated content need nofollow, sponsored, or UGC attributes. Genuinely useful links to relevant, trustworthy resources are fine to leave as standard dofollow links.

Does link insertion violate Google’s guidelines?
Not inherently, as long as the placement is relevant and adds genuine value to the reader. It becomes a problem only when links are inserted purely for manipulation, without any real relevance to the surrounding content.

Final Thoughts

Understanding the difference in a dofollow/nofollow link in SEO helps you build a backlink profile that looks natural, earns real ranking value, and stays safely within search engine guidelines. Focus your outreach efforts on earning dofollow links from relevant, trustworthy sources, don’t shy away from nofollow links since they still bring traffic and diversity, and always prioritize genuine relevance over raw link volume. Combined with solid on page and technical fundamentals, a healthy, natural link profile is one of the most durable advantages a website can build over time.
