What Are GEO and AEO? SEO in the Age of ChatGPT

Generative search engines like ChatGPT, Perplexity, and Google AI Overviews have become the first place users turn to. This shift added two new sibling terms to the SEO vocabulary: GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization).

GEO (Generative Engine Optimization) GEO is the optimization discipline that makes sure your brand is cited correctly and positively inside generative AI engines. Where classic SEO chases keyword rankings, GEO chases citations inside the AI's answer sentence.

AEO (Answer Engine Optimization) AEO is optimization for answer engines that respond to questions directly (Google AI Overview, Alexa, Siri). Content is written to be short, scannable, and "quotable as a sentence". FAQPage schema, entity markup, and crisp definitions are the main levers here.

Differences from Classic SEO - **SEO:** The user finds the link to click. - **AEO:** The engine gives the answer directly; source is optional. - **GEO:** The engine generates an answer and cites your brand inside the text.

Strategy: Running All Three Together In 2026 the winning brands run SEO, AEO, and GEO in parallel: 1. Classic SEO: page speed, backlinks, keywords for organic traffic. 2. AEO: FAQPage schema, crisp H2-H3 hierarchy, short paragraphs. 3. GEO: entity consistency, Wikipedia-style definition lines, third-party citations.

Conclusion GEO and AEO don't replace classic SEO, they layer on top of it. AI search is already a meaningful share of total search traffic and growing fast; brands that are invisible on both fronts will lose customers before the end of 2026.
