The AI Readiness Index.The world's 100 largest companies, every month.
Every month we check the websites of the world's 100 largest listed companies the way our free tools do: whether AI assistants can read who they are, how fast they load on a phone, and whether their tracking and consent work. Then we compare the sectors, from technology and banking to energy.
Latest: November 2026
The world's largest companies score 65.6 out of 100.

Press note
November 2026: The world's 100 largest listed companies score 65.6 out of 100 on the AI Readiness Index by Schnalz.net, a monthly check of their websites. By sector, healthcare and pharma companies lead with 76.9, and energy and materials companies trail with 51. 37.5% of the sites we could read state who they are in structured data and 19.4% publish an llms.txt file. 25% of the websites turned an automated visitor away, and bot protection like that can also stop AI assistants that read pages live.

Method
How the index works.
The companies
The 100 largest listed companies in the world by market value on 13 November 2026 (companiesmarketcap.com), each with its official website as recorded in Wikidata. The list stays the same from month to month, so a change is real movement, not a different sample.
The AI readiness score
Seven checks on the homepage as it is served, adding up to 100: structured data that names the organisation (25 points), any structured data (10), at least 100 words of text before JavaScript runs (20), AI search crawlers allowed in robots.txt (20), an llms.txt file (10), an XML sitemap (10) and HTTPS (5). The index and each sector's score are the average of their companies.
Speed, tracking and consent
Mobile speed is Google's PageSpeed Insights performance score on a simulated mid-range phone. Core Web Vitals are Chrome's real-user data, where Google publishes it. Tracking and consent come from our Tracking Check's code on the same visit, made without accepting cookies.
Sites that turn bots away
Some sites answer an automated visit with a block page or a challenge. We count them as turning bots away, measure their speed from Google's own visit, and leave them out of the AI readiness average, because we can't read their homepage. Bot protection like this can also stop AI assistants that read pages live.
Limits
One page per site. Google's test servers may see a different page than local visitors. We publish totals only, never a result for a named company.
Open data
The numbers are free to use with credit (CC BY 4.0). The data file has every month's totals.
