LLM Local Share-of-Voice Simulator

When consumers ask AI search engines questions like “Who is the most reliable emergency plumber in Norwalk, CT?”, ChatGPT, Perplexity, and Gemini do not show a list of 10 website links. Instead, they write out a sentence recommending 2 or 3 specific local companies.

LLM Share-of-Voice (SoV) measures the percentage of total AI recommendations your business receives compared to your competitors.

Example: If you run 10 local searches across 3 AI engines, the AI will make 60-90 total AI responses.
If your company is named 12 times and your competitor is named 18 times, your competitor owns 60% of the AI market share, while you own 40%.

This free simulator lets you run a quick 10-query check, plug in the results, and generate a visual audit showing who is winning the AI search market in your city.
