# Stunt Double Index

> The Stunt Double Index is an independent benchmark measuring how real AI agents experience the world's websites across discovery, information retrieval, task completion, delegated access and support.

The index scores domains across eight categories, using agents built on Claude, ChatGPT, Gemini and more. Scores are recomputed weekly. Use this file to understand what's available before crawling.

## Scoring categories

- **Brand awareness** — Can agents recognise you exist? Measures how often and how accurately leading agents mention your brand in unprompted research and comparison tasks.
- **Discovery** — Will they pick you? How well agents discover, shortlist and recommend your product when a user asks for a solution in your category.
- **Information retrieval** — Can they read your site? Quality of structured data, semantics and navigability for agents extracting pricing, specs and policies.
- **Market ranking** — Where do you sit in the lineup? Your relative placement vs. competitors when agents produce ranked lists for buyers in your market.
- **Accuracy** — Do they tell the truth about you? How often agents report correct pricing, features, availability and policies, and how often they hallucinate.
- **Task completion** — Can an agent complete a task on behalf of a user? Whether an agent can carry out a delegated interaction end-to-end: a primary call-to-action is exposed, the destination is reachable without a login wall, no bot-challenge blocks the first step, and the service signals support for agent-friendly auth.
- **Delegated access** — Do you let agents in, safely? Availability of scoped auth (OIDC, API keys, MCP), rate limits, and tooling for delegated agent sessions.
- **Contact & communication** — Can an agent reach a human? Whether an agent acting on a user’s behalf can find a way to contact or communicate with the business: contact page, support email, live chat, phone, help hub, or a social profile it can DM.
