Answer Engine Optimization (AEO) in 2025: The Complete Guide to Ranking #1 in ChatGPT, Perplexity, Gemini & Google AI Overviews

What Is Answer Engine Optimization (AEO)?

Answer Engine Optimization is the practice of creating and structuring content so that AI-powered search engines directly cite, quote, or feature your brand as the authoritative answer to user queries..

Unlike SEO (which drives clicks) or GEO (Generative Engine Optimization, which focuses on being mentioned), AEO is about becoming the primary source AI trusts and displays.

Key Stats That Prove AEO Is Mandatory in 2025

• 71% of all searches now end in zero-click results (Sparktoro, 2025)
• Google AI Overviews now appear on 84% of SERPs(SEMrush Sensor)
• Perplexity.ai has grown to 25+ million monthly users actively citing sources
• ChatGPT Search (launched Nov 2024) now shows live web citations in results
