rakuten.co.jp
This is how AI agents (not browsers) experience rakuten.co.jp. The score weights five categories of machine-readability; the ticks on the arc are the 31 individual checks behind it.
Top fixes
No reachable sitemap.xml. Publish one and reference it in robots.txt.
Fix: Publish /sitemap.xml and reference it from robots.txt with a Sitemap: line.
No HTTP Link: response headers. Emit canonical/alternate/describedby relations so HEAD-only or stream-rendering agents get them without parsing HTML.
Fix: Emit `Link:` headers for canonical, alternate-language, and describedby relations. Agents that fetch HEAD-only or stream-render rely on these.
Visible text is 5.7% of HTML weight (22028/383898 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%.
1 recommended-field warning(s). First: WebSite recommends "potentialAction" (improves agent comprehension). 1 block(s) skipped — type outside the set we check.
Fix: Validate your JSON-LD with Google Rich Results test. Fix missing required properties.
TTFB 6410ms. Slow. Agents time out aggressively.
Fix: Agents time out aggressively. Use edge caching for anonymous requests to cut TTFB below 800ms.
Heading issues: no <h1>.
Fix: Use a single H1 and avoid skipping heading levels (H1 → H3).

Fix it
Generated, ready-to-ship files for the gaps above — copy them or download and drop them into your repo.
This scan shows whether an agent can read the site. One free probe asks a real assistant a real buying question and records who it cited.
This graded your homepage. Your pricing, docs, and checkout live on other pages — the ones assistants actually quote when they recommend you — and a 78/100 here means agents are already missing things on the page you polish most. The $29 Deep Scan audits the whole site against all 31 checks, then emails a PDF with every failing check and its exact fix, ranked by what costs you the most visibility. One-time, delivered in minutes, no subscription.
Right now, only you know this score. Your buyers ask AI before they buy — certification is how you show them, and anyone comparing you to a competitor, that assistants can actually read, quote, and use your site.
- A public verification URL you can drop into a sales deck, a procurement questionnaire, or a partner review — anyone can check it, dated and signed.
- An embeddable badge for your site — the visible version of a property competitors can’t claim without earning the score.
- Weekly re-checks for a full year. A deploy that breaks agent access gets caught before it costs you recommendations — and before the certificate would lapse.
Sites under 70 can’t buy this at any price — that’s what makes displaying it mean something.

Get this report by email, then a heads-up when rakuten.co.jp’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.
This score says whether an AI agent could read rakuten.co.jp. AI traffic analytics says whether one actually came — and which pages turned it away.
