What is Generative Engine Optimization (GEO)?
Generative Engine Optimization (GEO) is the practice of ensuring your brand, products, and content are visible and accurately represented in AI-generated answers — across platforms like ChatGPT, Perplexity, Google AI Overviews, Claude, and Gemini.
Traditional SEO
User searches: "best running shoes"
→ 10 blue links
→ User clicks one
→ You need to rank in top 10
GEO (AI Search)
User asks: "What are the best running shoes for marathon training?"
→ AI writes a narrative answer
→ Mentions 3-5 brands with reasoning
→ You need to BE IN that answer
A Real Example
Here's what happens when someone asks ChatGPT about running shoes:
User prompt: "What are the best sustainable running shoes in 2026?"

GEO vs AEO — Same Thing, Different Name
You'll see both terms used: GEO (Generative Engine Optimization) and AEO (Answer Engine Optimization). They refer to the same practice. GEO emphasizes the generative/AI nature of the engines. AEO emphasizes the answer/conversational format. We use GEO as the primary term.
