Every link on the web carries an invisible instruction to search engines: pass ranking credit, or don't. That instruction is the difference between a dofollow and a nofollow link, and misunderstanding it leads to some of the most common mistakes in off-page SEO.
What Dofollow and Nofollow Actually Mean
By default, every link on the web is dofollow — it passes a portion of the linking page's authority to the page it points to, which is one of the core signals behind how search engines rank pages. A nofollow link carries a `rel="nofollow"` attribute in its HTML that tells search engines not to pass that ranking credit through, even though the link still works for actual visitors clicking it.
Why Nofollow Exists
Google introduced nofollow to fight comment and forum spam — without it, anyone could drop links in blog comments purely to manipulate rankings. Today it's expanded into related attributes:
- rel="sponsored" — for paid or sponsored links, like affiliate placements.
- rel="ugc" — for user-generated content, like forum posts and comments.
- rel="nofollow" — the general-purpose version for any link you don't want to vouch for.
Google treats these as hints rather than absolute directives, meaning a nofollow link can occasionally still be considered for ranking purposes in aggregate — but you should never count on that when planning an SEO content strategy around link building.
So Are Nofollow Links Worthless?
No — this is the most common misconception. Nofollow links still:
- Drive real, direct traffic when placed well.
- Build brand awareness and mentions, which search engines can factor in through other signals.
- Contribute to a natural-looking backlink profile — a site with 100% dofollow links actually looks suspicious, not ideal.
A healthy mix of both is exactly what shows up when you run a proper backlink profile audit.
How to Check Which Type a Link Is
Right-click "Inspect" on any link and look at its HTML for a `rel` attribute. No `rel="nofollow"` present means it's a standard dofollow link. Most SEO browser extensions can also color-code links on a page automatically.
Where This Matters Most
Two situations where the distinction really counts:
- Guest posting and digital PR — a dofollow link from a relevant, high-authority site is genuinely valuable link equity, while sites offering only nofollow links in a paid arrangement violate Google's guidelines outright.
- Assessing whether you've been hit by manipulative linking — a wave of low-quality dofollow links pointed at your site without your involvement is a signature of negative SEO, not organic growth.
A Note on Parasite and Manipulative Link Schemes
Buying dofollow links in bulk, or exploiting high-authority domains for link equity as seen in parasite SEO, are both against Google's guidelines and carry real penalty risk. The safest, most durable approach remains earning links through genuine digital PR link building and relevant outreach, not manufacturing them — and knowing how to evaluate a digital PR agency's SEO impact before hiring one.
International Considerations
If you operate across multiple countries, link attribution practices can vary by market and platform, which is one more reason international SEO needs its own linking strategy rather than a copy-pasted approach from your home market.
FAQ
Should I nofollow all my outbound links?
No. Only nofollow links you don't want to vouch for editorially — paid placements, user-submitted content, or untrusted sources. Genuine editorial citations should stay dofollow.
Do nofollow links help SEO at all?
Indirectly, yes — through traffic, brand visibility, and a naturally diverse backlink profile, even though they don't pass direct ranking credit the way dofollow links do.
Can too many nofollow links hurt my rankings?
Not directly, but if all of your backlinks are nofollow, it suggests you aren't earning genuine editorial citations, which is a missed opportunity rather than a penalty.
