Parasite SEO

Parasite SEO is the practice of publishing content on established, high-authority platforms—Medium, LinkedIn, Reddit, Substack, HubSpot's community, GitHub Pages, etc.—to rank in Google by borrowing that platform's domain authority. Instead of waiting months or years to build your own site's DR, you leverage platforms that already rank for almost anything. The term 'parasite' is value-neutral—it describes the relationship (your content benefits from the host domain's authority) rather than the ethics. Some uses are completely legitimate: a thought leadership article on LinkedIn, a product page on Product Hunt, or documentation on GitHub. Others are more aggressive—publishing exact-match keyword content on free platforms purely to intercept search traffic and redirect it. Where parasite SEO shines: ranking for competitive keywords before your own domain has authority, testing whether a topic converts before investing in owned content, and building topical authority signals through platform-native content. The risk: these platforms can change policies, remove content, or add nofollow to links at any time. You don't own the content's distribution. Used strategically alongside building your own site's authority, parasite SEO can accelerate results. Used as a replacement for owned SEO, it's a fragile strategy.
