AEO vs GEO vs SEO: which one matters for your site?

GEO (Generative Engine Optimization) is the broad practice of optimizing for any generative AI system. AEO (Answer Engine Optimization) is a subset focused specifically on direct-answer retrieval — the moment an AI picks one source as the definitive answer. All AEO is GEO, but not all GEO is AEO.

Both. SEO remains the highest-volume traffic channel. But AI search is growing at 40%+ year-over-year, and zero-click AI answers are cannibalizing top-of-funnel organic traffic. Sites that invest only in SEO are losing ground fast. The optimal strategy invests in a shared foundation (content quality, authority) and adds GEO/AEO as an incremental layer.

No. GEO optimizations like llms.txt, schema markup, and content structure are additive. They give AI crawlers better access without affecting how Googlebot indexes your site. The only risk is if you make content changes specifically for AI readability that reduce keyword density — but that risk is minimal if you prioritize clarity.

SEO: Ahrefs, Semrush, or Moz for backlinks and rank tracking; Google Search Console for indexing data. GEO: geodeck for llms.txt, AI visibility tracking, and schema auditing. AEO: geodeck's schema validator and FAQ page auditor. A unified platform like geodeck handles the GEO and AEO layers automatically.

geodeck focuses on the GEO and AEO layers. It automates llms.txt generation and hosting, validates and fixes schema markup, tracks AI mention frequency across ChatGPT and Perplexity, and submits new content via IndexNow for fast SEO indexing. It integrates with Google Search Console for the SEO data layer.
