The Crane Index Leaderboard

The most AI‑readable sites, by industry.

The top of every published Crane Index benchmark, in one document. Each site is given the same three deterministic reads, whether AI search can find and cite it, whether an agent can act on it, and whether a machine can confirm who it is. This is the monthly roll of honour: the highest scores in each list, every company named, every score verifiable live. It is re-run on the first of each month, so the movement becomes public record.

This edition

19 benchmarks, and the site leading each one.

Ranked by composite, so the leader of the whole field comes first. Each name links its full industry benchmark and each score can be checked live on the same scanners that set it.

Questions about the Crane Index

What does the Crane Index measure?

How readable and well-optimised a site is for AI, drawn live from its real pages across three deterministic reads: whether an AI engine can retrieve and cite it, whether an agent can act on it, and whether it is described accurately. Each is scored out of 100, and the composite is the Crane Index.

Why does AI readability matter now?

Because discovery is moving. In 2026, Google reported that its AI Mode in Search had passed a billion monthly users. What an assistant can read of an organisation comes down to the machine-readable layer of its site, the structured data Google Search Central documents.

How often is it re-run?

Every month, on the first, so the movement is a matter of public record rather than a single snapshot. Every constituent is named, ranked and archived, and each score can be re-run live against the site as it stands today.

The Crane Standard

The senior read,
once a week.

Most marketing newsletters are noise on a schedule. This is not that. Once a week I send a short, considered read on the shifts that actually change what you should do, across the AI shift, PPC, technical SEO and analytics. Filtered, weighted and signed off by me before it goes out. The judgement is mine, and now you can hear every edition in my own voice.
