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: Add a <script type="application/ld+json"> describing the page (Organization, Article, Product, FAQPage).

warnllms.txt presentDiscoverability

Found /llms.txt but missing H1 header and markdown links.

Fix: Publish /llms.txt at your domain root. Build a spec-compliant one at /tools/llms-txt-generator.

warnSitemap presentDiscoverability

sitemap.xml reachable but not referenced from robots.txt, so agents may miss it.

Fix: Publish /sitemap.xml and reference it from robots.txt with a Sitemap: line.

failLink response headersDiscoverability

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.

failText-to-markup ratioReadability

Visible text is 2.5% of HTML weight (14989/601329 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%.

warnCookie wall blocks contentReadability

Consent modal detected (trustarc.com); content still visible. Verify the modal does not block first-paint for screenshot agents.

Fix: Defer cookie consent overlay until after content is visible, or render behind the primary content. Agents without JS or with ad-blocking profiles see a blank page otherwise.

AgentSpeed score for sendgrid.com
<a href="https://agentspeed.com/scan/sendgrid.com"><img src="https://agentspeed.com/badge/sendgrid.com" alt="AgentSpeed agent-readiness score" height="56"></a>

Track this score

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

This score says whether an AI agent could read sendgrid.com. AI traffic analytics says whether one actually came — and which pages turned it away.
