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.
