The search landscape shifted in 2026. While traditional Google SEO remains essential, a new battleground has emerged: Answer Engines. ChatGPT, Perplexity, Microsoft Copilot, and Google’s AI Overview are fundamentally changing how people find information. They don’t rank pages—they synthesize answers. They don’t display links by default—they cite sources. This isn’t SEO. It’s something different. It’s Answer Engine Optimization (AEO).
