Dofollow vs Nofollow vs Sponsored vs UGC Explained

Every link on the web has a little tag stuck to it. Most people ignore it. Search engines do not. The rel attribute on a link tells Google how to interpret that link's endorsement. Get the mix wrong across your backlink profile and SpamBrain will sniff out the manipulation. A money site with 100% dofollow links looks exactly like what it is, a paid or built link profile. A profile with a natural scattering of nofollow, sponsored, and UGC links looks like a real business that people talk about in different contexts. This dofollow vs nofollow guide is a plain-English breakdown of all four link attributes that matter. I will tell you what each one does, when to use it, and how to blend them so your link profile passes both algorithmic and manual review.

The March Spam Update doubled down on Google's ability to detect unnatural link patterns. One of the signals it uses is the ratio of link attributes across a profile. If you are still operating under the old rule of "dofollow only, nofollow is worthless," you are leaving a footprint. Let me fix that for you.

The Four Link Attributes at a Glance

Now let me explain each one and how it shapes your link building strategy.

Dofollow: The Default Endorsement

A dofollow link is just a regular link with no rel attribute restricting it. By default, every link you create in WordPress, in a blog post, or on a PBN site is a dofollow link unless you deliberately add a nofollow, sponsored, or UGC tag. Dofollow links pass PageRank. They are the currency of SEO. When I build a PBN or place a niche edit, I almost always use a dofollow link because the entire point is to pass equity to the money site.

Google wants dofollow links to be editorial. If a link is paid for, Google says it should be nofollow or sponsored. I live in the real world where most paid link placements are dofollow, and I acknowledge that reality. But the risk is real. The November 2024 Site Reputation Abuse expansion specifically targets sites that sell dofollow links to unrelated third parties. If your money site's backlink profile is 100% dofollow links from guest posts and PBNs, you are painting a target on yourself. I dilute my dofollow links with a mix of the other attributes. I covered how in my types of backlinks guide.

When to use dofollow: Editorial links you earn through digital PR, niche edits that look editorial, guest posts on respected sites, and PBN links from your network. For anchor text strategy, I keep dofollow anchors varied as I described in my common PBN building mistakes article.

Nofollow: The Vouch-Away Tag

Nofollow was introduced in 2005 to combat comment spam. It tells Google, "I am linking to this page, but I do not endorse it." For years, nofollow links passed zero PageRank. SEOs ignored them. Then in March 2020, Google announced it would treat nofollow as a hint rather than a directive. That means a nofollow link can still be used by Google to discover new pages, understand context, and maybe even pass a little equity in certain situations. Google has been cagey about how much, but my own testing shows that nofollow links from high-authority, topically relevant pages can still move the needle, especially for brand signals.

I actively welcome nofollow links in a profile. If my backlink profile has a natural-looking 5-10% nofollow links, it looks less manipulated. Some of my strongest digital PR links from major publications have been nofollow because the publisher's CMS automatically applies the tag to external links. Those links still drive referral traffic and build brand authority. I have a client who ranks number one for a competitive term in part because a major news site linked to them with a nofollow tag. The link did not pass equity directly, but it drove real visitors, some of whom linked to the client's site from their own blogs with dofollow links. The indirect benefit was real.

When to use nofollow: Blog comments, forum posts, social media profiles, any link you do not control editorially, and any paid link you want to keep compliant. I also use a few nofollow links in my PBN anchor text mix, just to break the pattern.

Sponsored: The Paid Link Discloser

The sponsored attribute is Google's way of saying, "Tell me when money changed hands." If you pay a site to place a link, you should use rel="sponsored". The same March 2020 update that made nofollow a hint also introduced sponsored as a separate signal. Google treats it similarly to nofollow for ranking purposes, but it is the correct semantic tag for paid placements.

I know the reality: most SEOs who buy guest posts or niche edits do not use the sponsored tag. The site owner and the buyer both want dofollow juice. I operate in that grey area like everyone else. But I also recognize that a profile with zero sponsored links can look suspect if the site also has a pattern of obvious paid placements. I have started using sponsored tags on a small percentage of my paid links, especially those on sites that openly sell sponsored content, to create a natural-looking attribute mix. It also protects the host site from penalties. Google's Search Central documentation states that sites engaging in link schemes should at minimum qualify their links. I view the sponsored tag as a compliance tool when appropriate.

When to use sponsored: Affiliate links, paid guest posts on sites that openly accept sponsored content, and any link where money changed hands and you want to stay within Google's guidelines. I do not use it on PBN links because the whole point of a PBN is to simulate editorial endorsement.

UGC: The User-Generated Marker

UGC stands for user-generated content. Use it on links that come from your site's users: comments, forum posts, community submissions. This tag tells Google, "A user of my site placed this link, not me." Like nofollow and sponsored, it is treated as a hint. I do not actively build UGC links for SEO, but a natural profile will have them. If someone links to your site from a relevant forum or blog comment, that link likely carries a UGC or nofollow tag. It is a positive diversity signal.

When to use UGC: On any site you operate where users can post links. For PBN sites, I sometimes enable comments on a few articles and let the automated spam filter do its thing. It adds a layer of realism.

How Google Treated These Attributes After March 2020 and Beyond

Before March 2020, nofollow was a directive. PageRank did not flow. Google ignored those links for ranking purposes entirely. The 2020 change made all three restricted attributes (nofollow, sponsored, UGC) into hints. Google may choose to ignore them, but it may also use them for discovery and ranking, especially if the link comes from an authoritative source. The exact weight is uncertain. What is clear is that a natural mix of link attributes is a trust signal. The March Spam Update reinforced this. I saw profiles with excessive dofollow links from low-quality sources get devalued, while profiles with a varied attribute mix held steady.

Building a Natural-Looking Link Attribute Mix

For a typical money site, I aim for:

• 85-90% dofollow (the core equity links)
• 5-10% nofollow (natural mentions, blog comments, social profiles)
• 2-5% UGC (from forums, community sites, comments)
• 1-2% sponsored (if any paid links are properly tagged)

I do not obsess over hitting these exact numbers. I just check that my profile is not 100% dofollow. Ahrefs ($129/mo Lite) can show you the attribute breakdown of your backlinks. Run a report. If you see a wall of dofollow, you know what to do.

I also vary the attributes on my tier-2 links. When I build web 2.0s to power up a PBN, I use a mix of dofollow and nofollow. It looks more natural and reduces footprint.

How I Use These Attributes When Selling PBN Links

At BuyPBNLinks, every link we sell is dofollow by default because that is what clients pay for. But I advise every client to build additional links with nofollow and UGC attributes from other sources. A strong profile is not monolithic. If a client only buys dofollow links from us and does nothing else, they are building a profile with a single attribute. Over time, that can look unnatural. I recommend they also build a few branded social profiles, engage in relevant forums, and pursue some digital PR, all of which naturally produce nofollow links. The combination is far safer.

Common Mistakes With Link Attributes

• Mistake 1: Believing nofollow links are worthless. They are not. They drive traffic, build brand, and create profile diversity. A nofollow link from a major news site is more valuable than a dofollow link from a spam blog.
• Mistake 2: Using the wrong attribute for the wrong purpose. Applying rel="sponsored" to a genuine editorial link can confuse Google. Tagging paid links as dofollow without disclosure violates Google's guidelines. I use the right tag for the right situation.
• Mistake 3: Over-optimizing for a single attribute. A 100% dofollow profile is a clear footprint. Even if you build every link yourself, vary the attributes where possible.
• Mistake 4: Thinking UGC links will help rankings. They have minimal direct equity. They are for diversity and realism.
• Mistake 5: Stripping nofollow tags from PBN sites. Some builders configure their PBN sites to automatically make all outbound links dofollow. That is a detectable pattern. I keep the default WordPress settings, which add nofollow to comment links, and I manually set the money site links to dofollow.
