Parasite SEO · Content hosted on a high-authority third-party site
Parasite SEO consists of publishing content on a high-authority third-party site to borrow its ranking and reach. Google treats abusive forms under its site reputation abuse policy, and platforms heavily cited by AI, such as Reddit, also feed its GEO version.

What is it?
LLMrefs describes it as publishing on high-authority third-party domains to borrow their rankings and gain reach in traditional search, and notes that Reddit is often cited in AI answers. The practice covers legitimate uses (guest columns, communities) and abuses (commercial pages grafted onto a site with no editorial link).
What is Google’s position?
Google’s spam policies target site reputation abuse: third-party content published to exploit the host site’s ranking, without editorial oversight. For AI, Google’s guide adds that seeking inauthentic mentions is not helpful.
What should you do in GEO?
Favor authentic presence where AI already draws from: communities, media, reviews, with useful, signed contributions. Avoid disguised sponsored pages and bought mentions, which expose you to penalties.
Frequently asked questions
Does contributing to Reddit count as parasite SEO?

Do AIs cite these platforms?
Pew finds that Wikipedia, YouTube and Reddit are the most cited sources, both in Google’s AI summaries and in its standard results.
