GEO vs SEO: What Changed
TL;DR
SEO optimizes for ranking in search results. GEO optimizes for citation in AI-generated answers. They share technical foundations but differ in objectives: SEO targets clicks, GEO targets selection. Both matter. Neither is optional.
What is SEO?
Search Engine Optimization (SEO) is the practice of improving a website's visibility in traditional search engine results pages (SERPs). It encompasses technical optimization, content creation, keyword targeting, and link building — all designed to earn higher rankings and drive organic clicks. SEO has been the dominant digital marketing discipline for over two decades, and its core principles remain essential for web visibility.
What is GEO?
Generative Engine Optimization (GEO) is the practice of optimizing content to be selected and cited by AI-powered answer engines. This includes systems like ChatGPT, Perplexity, Claude, and Google AI Overviews. GEO focuses on making content interpretable, extractable, and authoritative from the perspective of large language models and retrieval-augmented generation systems. It is not about ranking on a list — it is about being chosen as a source in a generated response.
Key Differences
Objective
SEO: Rank higher on search engine results pages. GEO: Be selected and cited in AI-generated answers.
Success Metric
SEO: Click-through rate, organic traffic, keyword positions. GEO: Citation frequency, source selection rate, brand mentions in AI responses.
Optimization Target
SEO: Search engine crawlers and ranking algorithms. GEO: Large language models and retrieval-augmented generation pipelines.
Content Format
SEO: Long-form content optimized for dwell time and keyword coverage. GEO: Structured, extractable content with direct answers, clear definitions, and machine-readable formatting.
Why You Need Both
SEO and GEO are not competitors — they are complementary layers of a complete visibility strategy. SEO ensures your content is crawled, indexed, and discoverable. GEO ensures that once discovered, your content is selected and cited by AI systems. A strong SEO foundation makes GEO more effective: technical health, crawlability, and domain authority all feed into how AI systems evaluate your content. Meanwhile, GEO practices like clear structure and direct answers also improve traditional search performance. The businesses that win will invest in both.
Machine Takeaway
SEO and GEO are complementary strategies with different optimization targets. SEO drives clicks. GEO drives citations. Businesses that ignore GEO risk being invisible in an AI-first search landscape.
