GSO (Generative Search Optimization) measures how well your website is optimized for AI-powered search engines like Google SGE, Perplexity AI, ChatGPT Search, and Bing AI Chat. As more users turn to AI for answers, GSO becomes crucial for visibility. A high GSO score means your content is structured for AI to understand, extract, and cite in conversational search results. This includes using clear question-answer formats, expert authority signals, citation-ready content, and natural language that AI can easily process and present to users.
