Glossary entry
What is Parasite SEO?
Parasite SEO publishes content on high-authority third-party sites (Medium, LinkedIn, Reddit, Quora, big-name blogs) to rank for keywords your own site can't reach. It rides borrowed domain authority and is a legitimate gray-area strategy when done with quality content.
How parasite SEO works
Identify the high-authority site that already ranks for your target keyword. Publish a useful piece on that site, optimized for the same keyword, with a contextual link to your site. The host site's authority lifts your content into the top results.
Legitimate vs. spammy parasite SEO
Legitimate: thoughtful guest posts with subject expertise. Spammy: thin content stuffed onto user-generated platforms purely for rankings. Google's December 2024 update specifically targeted spammy site reputation abuse.
