What is GEO (Generative Engine Optimization)?

GEO (Generative Engine Optimization) is the practice of optimizing content to be cited, summarized, and recommended by AI engines like ChatGPT, Perplexity, Gemini, and Claude. Unlike SEO which targets search rankings, GEO targets AI citation — ensuring your content is the source AI engines reference when answering user questions.

What is the difference between GEO and SEO?

SEO optimizes for search engine rankings (Google, Bing). GEO optimizes for AI engine citations (ChatGPT, Perplexity, Gemini). SEO measures rankings and organic traffic. GEO measures citation rate, context accuracy, and source attribution across AI platforms. SEO uses backlinks and keywords; GEO uses structured data, answer blocks, and AI-friendly content formats.

Do I need both SEO and GEO?

Yes. In 2026, about 60% of information discovery still happens through traditional search, while 40% is shifting to AI engines. The most visible brands optimize for both channels. GEO and SEO share about 70% of best practices (structured data, quality content, E-E-A-T), so the incremental effort to do both is minimal.

How do I start with GEO?

Start by scanning your current AI visibility across all major engines (ChatGPT, Perplexity, Gemini, Claude, Grok, Mistral). Then deploy llms.txt, add TL;DR answer blocks to key pages, implement JSON-LD schemas, and allow AI crawlers in robots.txt. Monitor citation rates weekly using a tool like LoudPixel.

What Is GEO?

GEO stands for Generative Engine Optimization. It's the practice of structuring and optimizing your content so that AI engines — ChatGPT, Perplexity, Gemini, Claude, Grok, Mistral — cite you as a source when answering user questions.

Traditional SEO asks: "How do I rank higher in Google?" GEO asks: "How do I become the source AI engines trust and reference?"
