Dofollow vs Nofollow: Differences That Actually Matter
Dofollow backlinks are standard hyperlinks that pass PageRank and ranking signals when no blocking rel attribute exists. Nofollow links use rel="nofollow" to indicate they shouldn't be treated as endorsements, though Google may still crawl them — and sometimes even use them in limited ways.
This guide compares dofollow vs nofollow links across six critical dimensions. While dofollow links directly impact rankings, nofollow still matters for discovery, traffic, and profile diversity. I'll show you when each type earns its place.

Core Technical Differences
The fundamental difference lies in HTML attributes. Dofollow is the default state when a link lacks rel="nofollow", rel="sponsored", or rel="ugc". Nofollow links explicitly include the attribute to block PageRank flow.
Dofollow: (no rel attribute)Nofollow: Search engines parse these attributes during crawling to determine how to treat the link relationship. If you're curious about how link equity flows, this is where it starts.
SEO Impact Comparison
While dofollow links directly influence rankings by passing PageRank, nofollow links contribute indirectly — but not uselessly. Dofollow counts as a vote in link graphs and impacts rankings directly. Nofollow may influence rankings through traffic signals, brand searches, or discovery.
Google's John Mueller has confirmed that nofollow links can help with crawling and indexing. They also contribute to a balanced backlink profile diversity, which is a pattern Google's algorithms expect from natural sites.
When to Use Each Link Type
Follow Google's guidelines for proper link attribute usage. Use dofollow for editorial citations, resource pages, and earned media placements. Use nofollow for paid links, affiliate disclosures, untrusted user-generated content, and comment sections.
When in doubt about whether you want to endorse the linked content, default to nofollow. For high-risk placements like sponsored links, nofollow is mandatory to stay within Google's spam policies.
Risks and Penalties
Improper use of link attributes can trigger manual actions. Dofollow risks include penalties for bought links, unnatural patterns, and excessive exact-match anchor text. Nofollow risks are minimal unless used deceptively — for example, hiding paid links behind nofollow when you should have used sponsored.
Google's 2020 update made nofollow a hint, but the company still expects proper disclosure. Pure nofollow profiles may limit ranking potential but avoid penalties. A natural profile mixes both, which is why I always recommend earned editorial links as the foundation.
How to Check If a Link Is Dofollow
You can inspect the HTML of any page or use backlink tools like Ahrefs, Semrush, or Moz. In your browser's developer tools, look for rel="nofollow", rel="sponsored", or rel="ugc". If none of those are present, the link is dofollow by default.
Tools also show the dofollow/nofollow ratio in your backlink profile. Sudden spikes in dofollow links may trigger algorithmic review, so keep an eye on that.
Comparison: Dofollow vs Nofollow
Here's a quick reference table that covers the key attributes. I've drawn these from years of observing what actually works in the wild.
No single metric tells the whole story. Relevance and trustworthiness of the source matter more than the label.
Pros and Cons at a Glance
Pros of Dofollow: Can pass authority and support rankings. Helps search engines discover and understand linked pages. Usually better than nofollow for pure SEO value. Strong editorial links can improve trust and referral traffic.
Cons of Dofollow: Hard to earn at scale without real content or PR. Low-quality follow links can be worthless or harmful. Paid link acquisition is risky and often against Google policy. Not every follow link is valuable; relevance and source quality matter more than the label.

What the experts say
Nofollow links are treated as a hint — we may still crawl them and use them for discovery, but they don't pass PageRank directly. A natural profile includes both.
Use rel="sponsored" for paid links, rel="ugc" for user-generated content, and rel="nofollow" when you don't want to endorse the linked page. Proper disclosure helps us understand the relationship.
What it costs (and why prices are unreliable)
No standard price exists for dofollow backlinks. Earned editorial links can cost $0 in cash but require time, content, outreach, and PR effort; paid placements, guest-post packages, and link-selling schemes vary widely and are high-risk if they are disclosed as manipulative or violate policy.
Frequently asked questions
Do nofollow backlinks help SEO?
Indirectly. They don't pass PageRank but can drive traffic, aid discovery, and contribute to natural link profile diversity.
Can nofollow links become dofollow?
Yes, if webmasters remove the nofollow attribute. Some sites automatically convert UGC links to dofollow after moderation.
What percentage of backlinks should be nofollow?
Natural profiles typically show 60-80% dofollow. Higher nofollow ratios occur on UGC-heavy or commerce sites.
Does Google ignore nofollow links completely?
No. Google crawls them (unless blocked) and may use them for discovery, just not as direct ranking signals.
Should I nofollow all outbound links?
No. Only use nofollow for untrusted content. Editorial outbound links should remain dofollow to maintain credibility.
How do I check if a link is nofollow?
Inspect the HTML for rel="nofollow" or use tools like Ahrefs, Semrush, or browser developer tools.
