SEO vs GEO vs AEO: What is the Difference?
SEO (Search Engine Optimization) ranks pages in traditional web search engines like Google and Bing. GEO (Generative Engine Optimization) structures business data so AI models like ChatGPT and Claude cite your brand. AEO (Answer Engine Optimization) structures concise, factual Q&A markup so voice assistants and answer engines like Perplexity provide direct answers.
1. Search Engine Optimization (SEO)
Traditional SEO focuses on helping search engine web crawlers discover, render, and index website pages. The primary objective is ranking high on search engine result pages (SERPs) for target keywords, generating organic click-through traffic to website links. Key mechanisms include HTML hierarchy, Core Web Vitals, mobile responsiveness, XML sitemaps, and domain authority.
2. Generative Engine Optimization (GEO)
GEO targets generative AI synthesizers such as ChatGPT Search, Claude, and Google Gemini. When users ask conversational questions like “Who are the top technical partners for web app development in Bengaluru?”, GEO ensures the model retrieves authoritative, uncorrupted facts about your business. Key mechanisms include llms.txt files, interconnected Schema.org entity graphs, and third-party entity verification.
3. Answer Engine Optimization (AEO)
AEO focuses on direct factual retrieval engines such as Perplexity AI, Google AI Overviews, and voice assistants (Siri, Alexa). These platforms prioritize single, high-confidence answers extracted from structured Q&A markup, speakable selectors, and concise initial paragraphs.
