What Is a UGC Link?
A UGC (user-generated content) link is a hyperlink marked with rel="ugc" in its HTML anchor tag. This attribute was introduced by Google in September 2019 specifically to identify links that originate from content created by website visitors rather than the site's editorial team. It covers links submitted in blog comments, forum replies, community posts, product reviews, and any other section of a website where the public can add content that includes hyperlinks.
The ugc attribute is part of a family of rel values that help Google understand the context and trustworthiness of links. Before 2019, publishers were required to use rel="nofollow" to cover all non-editorial links, including both paid placements and user submissions. The introduction of ugc allows for more precise communication with search engines. A site that marks its comment links with ugc is clearly indicating "these links come from our users, not from us" which helps Google build a more accurate picture of the web's link graph.
Like sponsored and nofollow attributes, Google treats ugc as a hint rather than a hard directive. The search engine may choose to crawl pages linked from UGC content and, in some cases, may consider these links as part of a broader set of relevance signals. However, for SEO purposes, ugc links do not pass PageRank in the same way dofollow links do.
Managing UGC links is also a practical security concern. Sites that do not apply ugc or nofollow to user-submitted links are potentially enabling comment spammers to place dofollow links, which can cause search engines to associate the host site with low-quality or spammy destinations. South African businesses running WordPress sites, community forums, or product review platforms should ensure their user-submitted content sections handle outbound links appropriately.
UGC Links In Practice
A South African travel blog that allows readers to comment and share links to their own travel experiences needs to ensure those comment links carry the ugc attribute. Without it, any link posted by a commenter would appear as a dofollow editorial endorsement from the travel blog. Spammers frequently target open comment sections precisely to gain dofollow links, and sites that fail to restrict these can find themselves associated with low-quality link networks.
For South African e-commerce businesses running product review sections, applying rel="ugc" to all reviewer-submitted links is straightforward best practice. Major e-commerce platforms and content management systems handle this automatically, but custom-built sites need to implement it at the code level. Checking that your CMS applies the correct rel attributes to user submissions should be part of any technical SEO audit.
From a link building perspective, earning UGC links from active community sites like Reddit or South African forums such as MyBroadband can still generate meaningful referral traffic even without passing PageRank. High-quality, useful contributions to relevant communities build brand awareness and can lead to organic dofollow mentions elsewhere on the web.
FAQ
Do UGC links from forum posts and blog comments help with SEO?
UGC links do not pass PageRank in the traditional sense, so they have limited direct SEO value. However, they can drive referral traffic and brand awareness. Google may also use engagement signals from high-quality forum discussions as indirect ranking factors.
Should I apply rel=ugc to all links in my WordPress comment section?
Yes. WordPress applies rel=nofollow to comment links by default, which satisfies Google's requirements. You can update this to rel=ugc for semantic accuracy. Both attributes are treated as hints by Google and protect your site from link scheme associations.
