Hard for AI to use
AI readiness
AI assistants can technically reach your site but have almost nothing structured to quote.
The headline is the sum of the six pillars below. These three tiers are the check breakdown: they score the same site on a different scale, so the two totals do not have to match.
Critical access
The four ways a site blocks an assistant before content even matters.
Assistants can reach the site
All 7 primary AI crawlers are allowed by robots.txt.
2 / 2 passed
Content exists without JavaScript
Raw HTML has 186 characters of readable text; no H1, only 186 words.
1 / 2 passed
Missing pages fail safely
Either no sitemap.xml at /sitemap.xml or it returned 404.
0 / 2 passed
Controls are understandable
Server HTML has 0 H1 (want exactly 1), 0 H2, 0 H3, 0 landmarks. Flat or duplicated heading structure makes pages harder for agents to skim.

Fix these first
Failures first, then partials, biggest point loss at the top. Each card copies the prompt that asks a coding agent for exactly that fix.

Content without JavaScript

- 02
Accessible document structure
InteractionWhat this checksWhether the controls an agent meets expose real names and roles instead of anonymous clickable boxes.−7Use exactly one H1 per page, then a meaningful H2/H3 hierarchy, and real <nav>/<main>/<footer> landmarks.

- 06answerWhyGuessing paths is failing. The homepage content itself already describes the site: it's Berkshire Hathaway's official corporate home page with shareholder reports, letters, news releases, SEC filings, annual meeting info, and links to operating companies. That's enough to answer.
Answer. berkshirehathaway.com is the official corporate home page of Berkshire Hathaway Inc., the Omaha-based holding company led by Warren Buffett. It serves as an information hub for shareholders and investors, publishing annual and interim reports, Warren Buffett's and Greg Abel's letters to shareholders, news releases, SEC filing links, annual meeting information, corporate governance details, and common stock information, plus links to Berkshire's operating companies. It is aimed primarily at Berkshire shareholders, investors, and the media rather than at customers, though it also carries a GEICO auto-insurance quote advertisement.
