GEO clearly overlaps with SEO, but it also changes the goal from ranking for clicks to being retrieved, synthesized, cited, and accurately represented in AI-generated answers.

The debate is whether GEO becomes a specialized function, a layer within SEO, or a cross-functional capability across search, content, analytics, brand, and communications.
