Generative Engine Optimization (GEO) shifted from an experimental hobby to a board‑level KPI in under two years. If you need to track how ChatGPT, Perplexity, Google’s AI Overviews and other LLM‑style answer engines talk about your brand—and how often they recommend competitors—these five platforms cover the job better than anything else on the market.
