AI Reach Rank Inc. is the company behind AiRR, the independent measurement standard for AI search visibility, also known as Answer Engine Optimization (AEO) and Generative Engine Optimization (GEO). The AiRR Score benchmarks how brands appear, are described, and are recommended across ChatGPT, Gemini, Claude, and Perplexity, scored 0 to 100 per engine and per persona. Unlike platforms that also sell the optimization, AiRR only measures, which keeps the score a neutral, citable benchmark for marketing and finance leaders, boards, and investors. Its Persona AiRR Drift metric scores visibility through a defined ideal customer profile, not a generic prompt.
