GEO (generative engine optimization)

The mechanical difference from SEO is what the machine returns. A search engine returns ten ranked documents and you compete for position. An answer engine returns one synthesized paragraph assembled from a handful of retrieved passages, and you compete to be one of the passages it pulls from. That changes what you optimize. Ranking signals like backlinks and domain authority still influence which documents get retrieved, but retrieval is only step one. Step two is whether your specific sentences are clean enough to lift verbatim into an answer.

In practice that rewards writing that states a claim plainly, attributes it, and does not bury it under three paragraphs of throat-clearing. It rewards being quoted elsewhere, because these systems synthesize across sources and consensus across independent mentions carries weight. It is widely reported that Reddit is the single most-cited domain across AI answers overall, and that for professional and B2B questions LinkedIn is the leading cited social source, with its share rising sharply through 2026. Longer articles tend to get cited more often than short social posts, which are easier to scroll past than to quote.

The honest caveat: none of the major engines publish their retrieval or citation criteria, and the ones that publish anything publish guidance, not mechanics. Anyone quoting you an exact ranking formula for AI citations is guessing. Also worth knowing before you buy anything labeled GEO: in most of marketing, GEO has meant geographic or geo-targeting for two decades. Both meanings are in active use right now, sometimes in the same agency deck, so check which one a vendor means before you sign.
