GEO vs SEO — definition & why it matters | BrandGEO Glossary   GEO vs SEO
==========

 How optimizing for AI-generated answers differs from optimizing for ranked links.

SEO earns positions in a ranked list of links; GEO earns presence inside a synthesized answer. The overlap is real — technical health, authority and good content help both — but the success metrics differ (citations and mentions vs rankings and clicks), the surface differs (one answer vs ten blue links), and the levers differ (extractable answer passages, entity data and third-party corroboration matter disproportionately in GEO).

The budget question isn't either/or: search engines are themselves becoming answer engines. Treat GEO as the extension of SEO to every place a model composes an answer, and measure it separately — a #1 ranking with zero AI mentions is now a visible, quantifiable gap.
