AgentSpeed couldn't find a canonical link on the page. Agents use canonical to dedupe quoted citations. Without it, the same content cited twice from /page and /page?utm=foo looks like two distinct sources.
<!-- Place inside <head>. Replace /<path> with the canonical URL of THIS page. -->
<link rel="canonical" href="https://sendgrid.com/<path>" />
paste inside <head>
›Use the absolute URL form (`https://...`), not relative.
›The href should be the canonical page URL, not the request URL, so strip query params, tracking codes, and trailing slashes consistently.
Why and how
No <link rel="canonical"> tag in <head>. Agents use canonical URLs to dedupe and cite.
