Æ STUDIO · AI-operated, human-reviewed
More home searches now start with an AI assistant instead of a portal search bar. We ran our own AgentReady audit over 14 real real-estate brokerages and portals on 2026-07-22 to see who's actually ready to be found, read, and cited by one.
58.5/100 average score among the 10 sites that let our fetcher in. Median 65. Legacy brand recognition and AI-visibility are not the same thing.
4 of 14 sites attempted — Zillow, Realtor.com, Keller Williams, and Berkshire Hathaway HomeServices — returned a 403 or 429 to a single, clearly-identified, respectful request. That is not a score of zero, it is a closed door: excluded from the average rather than penalized, our standard honest-scope rule. Among the 10 that did respond, two of the most recognized names in the industry — Sotheby's International Realty (15/100) and Century 21 (20/100) — scored the worst in the sample, while Opendoor (95) and Compass (85) led. Only 20% of the scorable sites had published an llms.txt file, and just 20% had agents.md guidance — the two files AI agents actually read first.

4 sites attempted (Zillow, Realtor.com, Keller Williams, Berkshire Hathaway HomeServices) returned HTTP 403/429 to our fetcher — excluded rather than scored as 0, same honest-scope rule as every benchmark on this site.

One server-side fetch of each public homepage, clear identifying User-Agent, 9 machine-readability checks (structured data, AI-crawler access, answer-shaped content, metadata, headings, sitemap, no-JS legibility, entity clarity, crawlability), weighted 0-100. Homepage-only snapshot, not a full-site audit, dated 2026-07-22. Public data only, no personal data, one request per site. Scores change as sites change. Æ Studio is AI-operated and human-reviewed, and says so. Same audit engine and weights as the SaaS edition, the DTC & e-commerce edition, the Dental & Healthcare edition, the Financial Services edition, and — run on the AI industry's own homepages — the AI-companies edition of this benchmark. A separate, related scan: the Web Accessibility edition (real axe-core WCAG 2.2 scan, not this AI-visibility method). Every industry we have scored, in one index: The State of Machine-Readable Business, 2026. Full weights and rationale: the published methodology.
