It's one of the simpler schema types:

Why it helps for GEO

Combined with strong internal linking and content clusters, this structural clarity supports topical authority: engines understand not just the page, but its place in a well-organized body of knowledge. It's a small, low-effort signal that complements your broader content architecture.
