With the rise of AI search engines like ChatGPT and Perplexity, it is estimated that by 2026, AI search will handle 30%-40% of informational queries, and traditional SEO can hardly cover all exposure opportunities.

AEO (Answer Engine Optimization) is an optimization strategy focused on getting website content cited by AI search engines. Unlike traditional SEO which focuses on search result rankings, AEO pays attention to brand mentions in AI-generated answers. The popularity of AI search has changed user behavior; according to estimates for 2026, 30%-40% of informational queries are handled by AI engines, so relying solely on traditional SEO may miss a lot of exposure opportunities.

Different AI engines have significantly different citation logics:

• ChatGPT: Prefers high-authority domains (DA70+), cites 3-5 sources per answer round, new websites are less likely to be favored;

• Gemini: Tied to Google Search, higher probability of being cited if natural search performance is good;
• Claude: Academic tendency, structured data and metadata are key.
