What is Sponsored Tag? | Definition & Guide
A sponsored tag (rel="sponsored") is an HTML link attribute introduced by Google that identifies paid or sponsored hyperlinks — distinguishing them from editorial links for search engine crawlers.
Definition
A sponsored tag (rel="sponsored") is an HTML link attribute introduced by Google that identifies paid or sponsored hyperlinks — distinguishing them from editorial links for search engine crawlers. Announced in September 2019 alongside the rel="ugc" (user-generated content) attribute, the sponsored tag provides a more specific alternative to the broader rel="nofollow" attribute that had been used as a catch-all for non-editorial links since 2005. When applied to a hyperlink, the sponsored tag signals to search engines that the link was placed as part of a paid arrangement — such as a sponsorship, advertisement, or affiliate partnership — and should not pass organic ranking signals.
Why It Matters
Link attributes matter because they determine how search engines interpret the relationship between two websites. An editorial link without any rel attribute is treated as a vote of confidence — a signal that one site vouches for another's content. Paid links, however, are not genuine editorial endorsements, and Google's guidelines explicitly prohibit using paid links to manipulate PageRank.
Before the sponsored tag existed, webmasters used rel="nofollow" for all non-editorial links — whether paid placements, user-generated comments, or affiliate links. This blunt approach gave Google limited information about why a link was tagged. The sponsored attribute provides clarity: it tells crawlers specifically that money changed hands, enabling more nuanced algorithmic treatment.
For B2B SaaS companies engaged in content partnerships, sponsorships, and affiliate programs, understanding and correctly implementing the sponsored tag is essential for compliance with Google's guidelines. Failing to tag paid links appropriately can result in manual actions (penalties) that suppress rankings across the entire domain. Conversely, incorrectly tagging earned editorial links as sponsored needlessly discards valuable link equity.
How It Works
The sponsored tag is implemented as an HTML attribute within the anchor tag. The syntax is straightforward:
<a href="https://example.com" rel="sponsored">Anchor Text</a>
When to use the sponsored tag:
-
Paid placements — Any link placed in exchange for monetary compensation. This includes sponsored blog posts, paid guest articles, and advertorial content where the linking site received payment.
-
Affiliate links — Links that include affiliate tracking parameters and generate commissions for the referring site. While Google has stated that affiliate links can use either rel="sponsored" or rel="nofollow," the sponsored attribute is more semantically accurate.
-
Sponsored reviews — Product reviews or comparison articles where the featured company compensated the publisher. Even if the review is editorially honest, the financial relationship requires disclosure through the sponsored tag.
-
Ad units and display advertising — Banner ads, sidebar promotions, and other advertising placements that contain hyperlinks. Most ad networks handle this automatically, but custom ad placements require manual tagging.
When NOT to use the sponsored tag:
- Earned editorial links — Links placed by publishers because they genuinely found the content valuable. These should remain untagged to pass full link equity.
- User-generated links — Links posted by users in comments, forums, or community platforms. These should use rel="ugc" instead.
- Internal links — Links between pages on the same domain. These never require rel attributes.
Combining attributes — Multiple rel values can be used together. For example, a paid link that a site owner also wants to explicitly mark as nofollow can use rel="sponsored nofollow". Google treats rel="sponsored" as a strong hint (similar to nofollow) that the link should not pass PageRank, so combining them is redundant but not harmful.
Impact on SEO — Links tagged with rel="sponsored" do not pass traditional PageRank in Google's algorithm. However, Google has stated that it treats all link attributes (nofollow, sponsored, ugc) as "hints" rather than strict directives — meaning the algorithm may choose to consider or ignore these signals based on additional context. In practice, sponsored links provide referral traffic and brand visibility but should not be counted on for direct ranking benefit.
