What is AI Search Optimization (AISO)?
AI Search Optimization (AISO) is the practice of making your website more discoverable, understandable, and citable by AI-powered search tools like ChatGPT, Perplexity, Google AI Overviews, and Claude.
Why AISO Matters in 2026
Traditional SEO focuses on ranking in search engine results pages (SERPs). AISO goes further — it ensures AI systems can understand your content well enough to cite it accurately, recommend it to users, and include it in AI-generated responses.
With the rise of AI-powered search, a growing percentage of web traffic now comes from AI recommendations rather than traditional search results. If your content isn't optimized for AI, you're missing out.
