Generative Engine Optimization — GEO — is the practice of structuring your business’s online presence so that AI-powered tools like ChatGPT, Google’s AI Overviews, and Perplexity recommend your company when someone asks for help. For HVAC companies in South Fulton, Georgia, that means showing up when a homeowner in Sandtown or Cliftondale types “best AC repair near me” into an AI assistant instead of a search bar. The businesses that get cited in those AI answers are capturing calls before a competitor’s website even loads.
