AEO vs GEO vs SEO: What's the Difference?
The definitive guide to modern search optimization strategies
Quick Answer
SEO optimizes for traditional search engines (Google, Bing). GEO (Generative Engine Optimization) specifically targets AI-generated search results like Google's AI Overviews. AEO (Answer Engine Optimization) is the broadest term, covering all AI answer platforms including ChatGPT, Perplexity, Claude, and Gemini.
What Does GEO Stand For?
GEO stands for Generative Engine Optimization. It's a subset of AEO focused specifically on optimizing content for AI systems that generate new text based on user queries. This includes:
- Google's AI Overviews (formerly SGE)
- Bing Chat / Microsoft Copilot
- Any search engine with generative AI features
What is AEO in SEO?
AEO (Answer Engine Optimization) is the evolution of SEO for the AI era. While traditional SEO focuses on ranking in a list of blue links, AEO focuses on being cited as a source in AI-generated answers. Think of it as:
- SEO: "How do I rank #1 on Google?"
- AEO: "How do I get ChatGPT to recommend my brand?"
