From SEO to GEO
GEO (Generative Engine Optimization) is the methodology for optimizing websites to be cited and referenced by AI search engines (ChatGPT, Perplexity, Google AI Overviews).
How Is It Different from Traditional SEO?
SEO optimizes for Google rankings. GEO optimizes for AI citations. AI doesn't just read keywords — it understands context, verifies sources, and prefers reliable, structured content.
GEO 2026 Checklist
- Complete schema.org markup — Organization, Article, FAQPage, Service
- llms.txt — a file describing your sitemap for AI crawlers
- E-E-A-T signals — Experience, Expertise, Authoritativeness, Trustworthiness
- Content quality — in-depth articles, accurate facts, clear structure
- Cross-referenced sources — Wikipedia, Crunchbase, press coverage
- Page speed + Core Web Vitals — AI still uses PageSpeed signals
Measurable Results
With proper GEO setup, your website can appear in ChatGPT citations within just 2-4 weeks. This is a new traffic channel that traditional agencies haven't yet learned to leverage.
