How to Qualify Outbound Links with rel Attributes for Google
Last Updated: August 14, 2025Google lets you specify your relationship with linked pages by adding certain values to the rel attribute in your <a> tags. This helps Google understand which links are paid, user-generated, or that you don’t want to endorse or pass ranking signals to. Common rel values for outbound links: <a rel=”sponsored” href=”https://example.com/paid-content”>Sponsored Link</a> Note: Previously, nofollow was used for this, but Google now prefers sponsored for paid links. <a rel=”ugc” href=”https://example.com/user-post”>User Comment Link</a> If certain users consistently post quality content, you might consider removing ugc for their links. <a rel=”nofollow” href=”https://example.com/untrusted-link”>Untrusted Link</a> For internal links you don’t want crawled, prefer using robots.txt disallow instead. Using multiple rel values You can combine values by separating them with spaces or commas: <a rel=”ugc nofollow” href=”https://example.com/some-link”>Example</a> <a rel=”ugc,nofollow” href=”https://example.com/another-link”>Example 2</a> Important notes:
