The State of AEO in B2B SaaS, 2026: aggregate dataset

Aggregate results from a September 2026 reading of 274 well-known B2B software companies, measuring how readable each company's website is to AI assistants and their crawlers. For each site we checked: whether an llms.txt file is published and whether it passes seven structural checks; whether the homepage carries JSON-LD structured data and declares an Organization; whether robots.txt blocks any AI crawler; and whether the site could be read at all by a non-browser client. 251 of the 274 sites were readable. The file contains aggregates only, by measure and by software category. It contains no company names and no per-company results.
