Is off-page generative engine optimization different from traditional link building?

Traditional link building often focuses on earning links from relevant websites, while GEO looks at how content and brand information may be surfaced in generative AI responses. There is some overlap, especially around content quality and discoverability, but the two shouldn't be treated as identical. I'd be interested in seeing more research on which off-page signals actually influence AI citations. This article explores Reddit and off-page GEO in relation to organic growth.
