This is how AI agents (not browsers) experience langchain.com. The score weights five categories of machine-readability; the ticks on the arc are the 30 individual checks behind it.
Top fixes
Checks tagged “emerging” are 2026 agent-protocol standards most of the web hasn’t adopted yet — adopting early is an edge, not a defect.
No JSON-LD blocks found. Add a <script type="application/ld+json"> with a schema.org type for this page.
Fix · Webflow: Add JSON-LD in Page Settings → Custom Code (inside <head>) for the page’s type.
Found /llms.txt but missing H1 header and markdown links.
Fix · Webflow: Publish /llms.txt at your domain root. Build a spec-compliant one at /tools/llms-txt-generator.
Visible text is 3.7% of HTML weight (5781/155238 bytes). Low. Markup may be crowding out agent-usable text.
Fix: Heavy ad or navigation markup crowds out agent-usable text. Aim for a text-to-DOM ratio above 15%.
A Link: header is present but carries none of canonical/alternate/describedby — the relations agents consume.
Fix: Emit `Link:` headers for canonical, alternate-language, and describedby relations. Agents that fetch HEAD-only or stream-render rely on these.
Heading issues: 2 skipped level(s).
Fix: Use a single H1 and avoid skipping heading levels (H1 → H3).
No Content-Signal directives. Add e.g. `Content-Signal: ai-train=no, ai-summarize=yes` to declare granular AI usage policy beyond binary allow/disallow.
Fix: Add `Content-Signal:` directives to your robots.txt. This is the emerging standard (Cloudflare-driven) for declaring fine-grained AI usage policy beyond a binary allow/disallow.

This score clears the Bronze threshold (70+). Certification turns it into a dated, publicly verifiable attestation — a verification URL, an embeddable badge, and weekly monitoring for a full year. Scores under 70 can’t buy this, which is what makes displaying it mean something.

Get this report by email, then a heads-up when langchain.com’s agent-readiness actually changes — a check regressing, or the composite dropping.
Two things never trigger an email: a score change caused by us publishing a new rubric, because that is a different instrument rather than a change to your site, and movement explained only by timing-derived checks, which shift run to run on a site nobody touched.
Want it on your own schedule, with Slack or a webhook instead of email? Score-drift monitoring is on every paid plan.
