Search "AI answer scoreboard" or "AI leaderboard" and you'll mostly find tools that rank the AI models — LMSYS Chatbot Arena, the HuggingFace Open LLM Leaderboard, Artificial Analysis. Those score the models. RadRank scores your business: does AI name you when a customer asks? Same-sounding words, opposite thing.
01AI Answer Share-of-Voice (AI-SoV)
AI Answer Share-of-Voice (AI-SoV)
The percentage of category prompts whose AI-assistant answers name your business, relative to all businesses named in those answers, measured per engine and averaged across the engines that actually answered. In plain terms: when a buyer asks an AI for the best option in your category, how often are you the answer?
Not a benchmark score for a language model. Not a leaderboard ranking LLMs like LMSYS Chatbot Arena or the HuggingFace Open LLM Leaderboard.
02Answer-engine scoreboard for businesses
Answer-engine scoreboard for businesses
A tool that measures a business's AI Answer Share-of-Voice and returns an inspectable receipt — the exact prompt asked, which engines answered, the verbatim answer text, and the competitor names extracted from it. RadRank is one. It measures; it does not sell the fix it grades (see the Neutrality Pledge).
Not a model leaderboard. A model leaderboard ranks how good the AIs are; an answer-engine scoreboard ranks how visible your business is inside the answers those AIs give.
03Answer Engine Optimization (AEO)
Answer Engine Optimization (AEO)
The work of making a business easy for AI answer engines — ChatGPT, Claude, Perplexity, Gemini, Google AI Overviews — to confirm, understand, and name when a buyer asks for the best option in a category. Also called Generative Engine Optimization (GEO). AEO improves your odds of being named; nobody controls AI output, and no honest tool guarantees a placement.
