What is GEO (Generative Engine Optimization)?
Published July 2025 · 8 min read
Generative Engine Optimization (GEO) is the practice of optimizing your website so that AI-powered search engines — like ChatGPT, Perplexity, Google AI Overviews, and Claude — can discover, understand, and cite your content.
If traditional SEO is about ranking #1 on Google, GEO is about being the source AI engines quote when users ask questions.
Why GEO Matters Now
AI search is exploding. By 2025, over 1 billion people use AI search engines monthly. Perplexity alone handles 100M+ queries per day. Google now shows AI Overviews for a large share of searches.
If your site isn't optimized for AI discovery, you're invisible to this growing audience. GEO ensures your content is crawlable, understandable, and citable by AI models.
