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.

Frequently asked questions
What are the main differences between GEO and SEO?+
GEO (Generative Engine Optimization) focuses on optimizing content for AI search engines to cite, while SEO primarily improves rankings on Google. GEO requires clear structured content, E-E-A-T signals, and accessibility for AI crawlers, aspects that traditional SEO does not emphasize.
Why is E-E-A-T important in GEO?+
E-E-A-T (Experience, Expertise, Authoritativeness, Trustworthiness) is crucial in GEO because AI search engines, like Google AI Overviews, prioritize citing content from reliable sources with verifiable information. Anonymous content will not be cited for important topics.
What should Vietnamese websites prepare for GEO in 2026?+
Vietnamese websites need to complete schema.org markup, create an llms.txt file, and ensure fast page load speeds to meet GEO standards. Integrating E-E-A-T and having clear content structure are also essential for being cited by AI search engines.
How can content be optimized for AI search engines?+
To optimize content for AI search engines, you should use appropriate schema JSON-LD, ensuring that the content is clearly structured and understandable. Additionally, providing clear author information and reliable reference sources will enhance the chances of being cited.
