GEO: What the Research Says About AI Search

Short summary

Three independent research streams show AI systems significantly cite content with expert quotes (+41% boost), original data, and self-contained answers. Platform strategies differ: ChatGPT rewards unique framing and extractable data, Perplexity prioritizes multiple ranked sources, and Google AI Overviews integrate traditional search rankings. Keyword stuffing actively hurts performance; writing fluency alone provides no benefit without substantive content changes.
