Score 65 out of 100, grade C

Microsoft's homepage scores 65 out of 100 (grade C) for AI readiness. Its strongest area is crawl access (100), and the biggest drag is citability (10). The single most valuable fix, "serve your full content in the initial html", is worth about 10 points on its own.

What we found

What we would change first

  • CriticalCitability-90 pts

    0 citable facts found in the raw HTML. LLMs cannot cite what isn't in the source.

    0 numbers, prices, dates, measurements or certifications detected in the raw text

  • CriticalToken economics-66 pts

    Reading this page costs an agent ~65,316 tokens for ~1,010 tokens of actual content, a ~65× cost multiplier (98% markup, scripts, and boilerplate).

    ~65,316 raw tokens vs ~1,010 content tokens, ~65× cost multiplier

  • CriticalActionability-20 pts

    11 distinct call(s)-to-action exist only in the JS-rendered DOM, absent from the raw HTML, so agents working from the source are likely to miss them.

    "accept", "reject", "manage cookies", "no, thanks", "more"

  • CriticalVisibility-12 pts

    3 heading(s) shown to humans are missing from the raw HTML, they exist only after JavaScript rendering, so crawlers that skip rendering are likely to miss them.

How this report was made

One automated scan of https://www.microsoft.com/en-us/ on 3 October 2026, with the same engine (v0.3.0) as the free Siteiz scan. We fetched the page twice: as raw HTML, the way AI crawlers receive it, and rendered in a real browser, the way people see it. Scores are deterministic rules, not an AI opinion. Sites change, so this is a snapshot of that day. Methodology
