Methodology

How is this ranking calculated?

Jourdechance queries 4 LLMs (ChatGPT GPT-4o, Claude Sonnet, Gemini Pro, Perplexity) with 30 representative prompts for the Public Relations & Comms sector. Each cited brand receives a weighted visibility score based on its position in the response, citation frequency and context (direct recommendation vs mere mention). The final score is a weighted average across all 4 models. Quarterly updates.
