Top fixes

failJSON-LD presentStructured data

No JSON-LD blocks found. Add a <script type="application/ld+json"> with a schema.org type for this page.

Fix · Next.js: Emit JSON-LD from a Server Component or the Metadata API: a <script type="application/ld+json"> with Organization / Article / Product for the page.

warnCanonical URLDiscoverability

Canonical points elsewhere: https://browserbase.com/. Verify intent (cross-domain canonicals are valid but unusual).

Fix · Next.js: Set alternates.canonical in the Metadata API (generateMetadata) for each route.

failText-to-markup ratioReadability

Visible text is 3.1% of HTML weight (11769/379890 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%.

failHeading hierarchyReadability

Heading issues: no <h1>; 2 skipped level(s).

Fix: Use a single H1 and avoid skipping heading levels (H1 → H3).

warnMeta descriptionReadability

Meta description is 41 characters; aim for 50–200 so it's neither thin nor truncated.

Fix: Add `<meta name="description" content="...">` to your primary pages. Agents frequently use it as a summary.

failSchema type coverageStructured data

Page looks like Article|BlogPosting|NewsArticle; missing JSON-LD type(s): Article|BlogPosting|NewsArticle.

Fix: Align JSON-LD type to page purpose. Product pages without Product markup are skipped by agent shopping flows.

Track this score

Get this report by email, then a heads-up when browserbase.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.
