SEO term

Barnacle SEO

/ˈbär-ni-kəl/  noun

Attaching your brand to high-authority platforms that already rank well in search, instead of only building your own site's authority.

Named for the barnacle, which fixes itself to a whale or a ship's hull and rides where the current runs strongest. You earn visibility on a platform that already has it.

Coined by Will Scott in 2008. Still standard SEO vocabulary, and still working in the AI-search era.
