FAQ
AEO & GEO, plain answers.
What is the difference between AEO and GEO?
AEO (Answer Engine Optimization) and GEO (Generative Engine Optimization) are used interchangeably in 2026. Both describe optimizing content so AI engines like ChatGPT, Perplexity, and Google AI Overviews cite it inside their answers, rather than only ranking a link. GEO names the generative layer specifically; AEO grew from optimizing for direct-answer features.
How much more valuable is AI search traffic?
AI-referred visitors convert about 4.4x higher than standard organic visits on average, spend roughly 68% more time on site, and in about a third of sessions convert at twice the organic rate. The traffic is smaller in volume today but higher in intent and value.
What content actually gets cited by AI engines?
Princeton research found citing sources, adding statistics, and including quotations lifts AI visibility 30 to 40%. Pages with FAQ schema earn about 3x more citations than prose, tables get extracted at 81% versus 23% for paragraphs, and content updated within 30 days earns 3.2x more citations than older content.
