What Is a Dofollow Link?
A dofollow link is the default type of hyperlink on the web. Any standard <a href=”…”> tag without a rel=”nofollow”, rel=”sponsored”, or rel=”ugc” attribute is treated as dofollow by search engines. There is no actual rel=”dofollow” value in HTML – the term is simply used to describe a link that passes link equity to the linked page.
Dofollow links are the most valuable type of backlinks for SEO. They pass authority to improve search rankings of the destination page, effectively telling search engines that the linking site endorses and vouches for the content it points to. This transfer of link juice is a core mechanism behind how search engines determine which pages deserve higher positions in results.
Using descriptive anchor text for dofollow links helps search engines understand the topic of the linked page, further strengthening the SEO value of the connection. Guest blogging is a common way to earn dofollow backlinks from authoritative sites in your niche.
What is a Nofollow Link?
A nofollow link includes the rel=”nofollow” attribute in its HTML tag. Originally introduced in 2005 by Google and Blogger to combat comment spam, the nofollow attribute instructs search engines not to pass ranking power or link equity to the linked page.
However, since Google’s September 2019 announcement, nofollow links are treated as hints rather than strict directives. This means search engines may still choose to crawl, index, or even credit nofollow links under certain conditions – a significant shift from the original directive model.
Nofollow links do not pass authority in the traditional sense, but they can still drive referral traffic and enhance brand visibility. Links in blog comments and forums should generally be nofollow to avoid endorsement of untrusted content. The rel=”nofollow” attribute is used for links where endorsement is not intended, making it essential for user-generated areas of any website.
Sponsored and UGC Attributes
Beyond the classic dofollow and nofollow distinction, Google introduced two additional rel attributes in 2019 to give webmasters more granular control over how links carry signals:
- Sponsored (rel=”sponsored”) – Paid links should use rel=”sponsored” to comply with search engine guidelines. This includes advertisements, paid placements, affiliate links, and sponsored posts. Google explicitly prefers this tag over generic nofollow for any link involving compensation. Failing to properly tag paid links can trigger penalties under Google’s spam policies.
- UGC (rel=”ugc”) – User generated content requires the use of rel=”ugc” to prevent passing trust to unverified submissions. This applies to links in forum posts, blog comments, reviews, and any content added by users rather than site owners.
These attributes can be combined – for example, rel=”nofollow ugc” or rel=”ugc sponsored” are both valid. Despite being available for years, adoption remains remarkably low. According to LoudGrowth’s 2026 backlink study, rel=”ugc” appears in only about 1.2% of all links, while rel=”sponsored” shows up in roughly 0.26%. Most sites still rely on plain nofollow to handle all non-editorial outbound links.
Link Equity/PageRank
Link equity – often called link juice – is the SEO value that flows through dofollow links from one page to another. Dofollow links pass link equity to the linked page, helping search engines assess the authority, trust, and ranking potential of the destination page. This mechanism is fundamental to how algorithms like PageRank determine search rankings.
Nofollow links do not pass link equity to the linked page under the traditional model. However, since Google now treats nofollow as a hint rather than a directive, there’s some ambiguity: a nofollow backlink might still contribute partial value in contexts where anchor text relevance, source authority, or co-citation signals are strong.
The practical implication for your SEO strategy is clear – not all links are equal. A single dofollow link from a high domain authority site can deliver more real SEO value than dozens of nofollow backlinks from low-quality sources. That said, nofollow links can still drive referral traffic and enhance visibility, making them a valuable component of any balanced link profile.
Dofollow vs Nofollow vs Sponsored vs UGC
Understanding the differences between these four link types is essential for any effective SEO strategy. Here’s a clear comparison:
| Attribute | Passes Link Equity | Typical Use | HTML rel Value |
|---|---|---|---|
| Dofollow | Yes | Editorial links | None |
| Nofollow | Treated as a hint | Comments, untrusted links | nofollow |
| Sponsored | Paid links | Advertisements & sponsorships | sponsored |
| UGC | User-generated content | Forums & reviews | ugc |
According to data aggregated from SEMrush and Ahrefs studies, the distribution across top websites breaks down to approximately 60.3% dofollow, 31.8% nofollow, 5.1% UGC, and 2.8% sponsored. Websites with a mix in the neighbourhood of 55–65% dofollow links tend to perform better in search than sites with near-100% dofollow – a natural-looking profile avoids suspicion of link manipulation.
Why Should You Check DoFollow and NoFollow Links?
- Balance SEO Impact: A balanced link profile includes both dofollow and nofollow links. Maintaining this balance is crucial for SEO success because a profile with only dofollow links may raise red flags to search engines. Our nofollow link checker tool helps you monitor this ratio against industry benchmarks.
- Improve Link Building: Knowing which sites pass authority through dofollow links and which don’t lets you prioritize your link building outreach. Focus your efforts on opportunities that deliver real SEO value rather than wasting budget on placements that won’t move the needle on search rankings.
- Avoid Penalties: Improperly tagged paid links and sponsored content can lead to manual actions from Google. By running regular link analysis with a nofollow checker, you can identify outbound links that need proper rel=”sponsored” or rel=”ugc” attributes before they become a compliance problem.
- Monitor Competitors: Use the dofollow nofollow link checker to review competitor pages and understand how they structure their external links. This competitor analysis reveals which sites they’re passing authority to and helps you identify new link building opportunities in your niche.

Ways to Use the Tool (Based on Your SEO Goals)
Audit Guest Post Opportunities
Before investing time writing a guest post pitch, check whether the target publication actually gives dofollow links to contributors. Many guest posts end up with nofollow links – which still drive referral traffic but won’t pass the link equity you might be counting on for your SEO efforts.
Review Competitor Outbound Links
Paste a competitor’s key pages into the checker to map their outbound link strategy. You’ll see which partners, tools, and resources they endorse with dofollow links versus which get nofollow treatment. This intelligence shapes your own link building campaigns.
Verify Sponsored Link Placements
If you’ve paid for a link placement or advertisement, confirm it carries the correct rel=”sponsored” attribute. Links that pass SEO value without proper disclosure could be flagged as part of a link scheme, putting both your site and your partner at risk.
Analyse Affiliate Links
Affiliate links are considered paid links and should carry a rel=”sponsored” tag. Run affiliate-heavy pages through the checker to identify any links that are incorrectly passing authority. Studies show that affiliate-heavy sites often underuse the sponsored attribute even years after its introduction.
Perform Technical SEO Audits
As part of a broader SEO audit, use the checker to evaluate how your own pages distribute link equity. Identify whether your internal links and external links are correctly attributed, and ensure you’re not accidentally nofollowing important outbound endorsements.
Validate Client Backlink Reports
For agency teams and SEO professionals managing client campaigns, the tool provides quick verification of link placements. Before reporting a new dofollow backlink to a client, confirm its status directly from the live page rather than relying on cached data from third-party platforms.
Support Link-Building Campaigns
During active enterprise link building campaigns, use the checker to validate each placement as it goes live. Link checkers identify dofollow and nofollow links instantly, ensuring your campaign delivers the ranking power your strategy demands.
FAQs
What is the difference between dofollow and nofollow links?
Dofollow links pass SEO value and link equity to the linked page, directly influencing search rankings. Nofollow links include the rel=”nofollow” attribute, which historically blocked authority transfer – though Google now treats nofollow as a hint rather than a strict directive. A balanced link profile includes both dofollow and nofollow links, as this appears natural to search engines.
How does a nofollow link look?
A nofollow link includes rel=”nofollow” in its HTML tag: <a href=”https://example.com” rel=”nofollow”>Anchor Text</a>. You can verify this by right-clicking a link in your browser, selecting “Inspect,” and checking the rel attribute in the source code – or simply paste the webpage URL into our nofollow link checker.
How does a dofollow link look?
A dofollow link is simply a standard HTML link without any nofollow, sponsored, or ugc attribute: <a href=”https://example.com”>Anchor Text</a>. Since dofollow is the default state, there’s no explicit rel=”dofollow” value in HTML. If a link tag tells search engines nothing via a rel attribute, it’s treated as dofollow.
Is this tool really free?
Yes. This is a completely free SEO tool with no hidden fees, paywalls, or premium tiers for basic functionality. You can check dofollow and nofollow links on as many pages as you need.
How accurate is the link analysis?
The tool scans the live HTML source code of the page in real time, reading the actual rel attributes present in each link. This delivers highly accurate results based on what search engines see when they crawl the page. Note that links rendered exclusively through JavaScript may not be detected by any static HTML parser.
Can I use this tool for multiple websites?
Absolutely. You can analyze multiple URLs without restrictions. Check your own pages, competitor sites, client websites, or potential link building targets – there are no per-domain limits.
Do I need to create an account to use this tool?
No. You don’t need to sign up, register, or provide any personal information. Open the tool, enter your URL, and get your link analysis immediately.
Do I need to install this tool?
No installation is required. The dofollow nofollow link checker runs entirely in your browser. It works on all modern browsers without plugins, extensions, or downloads.
