Rel Sponsored vs Nofollow vs UGC: Choosing the Right Attribute
In this article
Rel sponsored vs nofollow? The rule is short. Paid or advertising links get rel=”sponsored”. Links your users add get rel=”ugc”. And rel=”nofollow” is for everything that fits neither, when you’d rather Google didn’t connect your site with the target. Editorial links you actually stand behind? No rel attribute at all. If you place and receive links on one site (or across a whole network), the sections below give you one decision per link.
What Do Sponsored, UGC and Nofollow Tell Google?
They describe your relationship with the page you link to. That’s it, as Google’s guide to qualifying outbound links explains. One value per kind of link:
- sponsored: ads and paid placements.
- ugc: comments, forum posts and anything else users write themselves.
- nofollow: the fallback. The other values don’t fit, and you’d rather Google not associate your site with the linked page, or crawl it from your site.
- no attribute: a regular link. Google can fetch and parse it, no qualification needed.
Rel Sponsored vs Nofollow: Which One Fits a Paid Link?
Sponsored. It’s the attribute built for paid links, although Google will take nofollow on them too. According to Google’s spam policies, buying and selling links for advertising or sponsorship is a normal part of the web and breaks no rules, as long as the link carries either value. So what counts as paid? Banner ads, paid placements, a product sent over in exchange for a review with a link. All of it. The difference between the two values is subtle but real: sponsored says why the link exists, nofollow only tells Google what to do with it. And no, there’s no compliant way to disguise a paid link (people have tried, trust me). Label it and move on. More on placements in our articles on link building.
When Should You Use Rel UGC?
Whenever users post the link themselves - comments, forum threads, reviews, profiles. Google also lets you drop the attribute for members who have posted high-quality contributions consistently over time. Which makes it a nice little reward for trusted regulars. In practice I’d have the CMS or forum template add ugc by default and strip it only for contributors you pick by hand. But don’t treat it as a spam filter. Unmoderated user content pulls in spam, full stop, and the attribute is one piece of moderation, not a replacement for it.
When Is Plain Nofollow the Right Choice?
When you don’t want to vouch for a link that’s neither paid nor user-added. Think a source you’re criticising, a claim you can’t verify, a destination you simply don’t trust. What about internal links? Not the job for nofollow. For pages on your own site you don’t want crawled, Google recommends a robots.txt disallow rule instead. Aha, and that old habit of slapping nofollow on every outbound link? It kills the value of honest editorial citations. Those should stay plain.
Can You Combine Rel Values on One Link?
Yes. Google accepts several rel values on one link, separated by a space or a comma. Both of these work:
<a rel="ugc nofollow" href="..."><a rel="ugc,nofollow" href="...">
Combining makes sense when two descriptions are true at once. Say, a paid link sitting inside user content, or a sponsored post published on a forum. Otherwise, keep it lean. Add a value only if it actually describes the link, because stacking every attribute out of habit just makes your markup less accurate.
A Quick Checklist for Links You Place and Receive
Four questions, in this order. Stop at the first one that fits:
- Did someone pay for the link with money, a product or another benefit? Use sponsored.
- Did a user add the link? Use ugc.
- Do you not want to vouch for the target? Use nofollow.
- Is it an editorial link you stand behind? Add no attribute.
Same logic for links pointing at you. Paid for a placement that links to your site? Then the publisher should qualify that link too. If you own a network, apply these rules the same way on every property - no exceptions for the “small” sites. Hosting lots of sites on one server comes with its own single-host link risks, and that’s a separate review.
Reused and expired domains? Same rules for qualifying links. Our guide to hosting expired domains safely covers how to keep their history intact.
And if you run sites across regions, diverse IP proxy hosting with EU and USA addresses handles the infrastructure side. It won’t change how any single link should be labelled, though.
Summary: Name the Reason for Each Link
Sponsored for paid links, ugc for user content, nofollow as the fallback, nothing for editorial links. Google is fine with qualified paid links. Unqualified ones count as link spam. So the whole rel sponsored vs nofollow question really comes down to stating why a link exists, and sponsored states it most clearly.
FAQ
Is rel=”nofollow” still acceptable for paid links?
Yes. Google’s spam policies accept either nofollow or sponsored on paid links. Sponsored is more precise, though, because it names the commercial relationship. Make it your default for new placements.
Do internal links need nofollow?
No. For pages on your own site you don’t want crawled, Google recommends a robots.txt disallow rule. Leave internal links plain so crawlers can follow your site structure.
Should every comment link carry rel=”ugc”?
As a default, yes. Google lets you remove the attribute for contributors who have posted high-quality content consistently over time. Keep it on for new or unknown users, and take it off only for people you trust.
