METHODOLOGY
Methodology: How the Score Works
Same prompt set, every week
Each sector is measured against a fixed set of unbranded prompts; because the set does not change week to week, scores stay comparable over time.
Multiple answer engines
Prompts run across six answer engines including ChatGPT, Gemini, Perplexity, Claude and Copilot, reducing single-model bias.
A visibility score out of 100
A brand's score is its visibility across the sector's prompt set, normalised to 100 — where 100 is the most visible brand in the sector that week.
Published openly
The index is public, so any visibility claim can be verified here, independently of the vendor making it.
