seo/og-url · Open Graph URL

Every route should include an og:url with its canonical address.

Severity: warning

What it checks

Every route should include a <meta property="og:url"> tag (own or inherited). A missing or empty tag is flagged.

Why it matters

og:url tells social platforms the canonical address to attribute shares and likes to, consolidating engagement on one URL. The Open Graph protocol lists og:url among its required properties, alongside og:title, og:type, and og:image.

og:url might seem redundant with <link rel="canonical">, since most consumers can fall back to the canonical URL when og:url is absent. But that conflates two different jobs: canonical tells search engines which URL to index, while og:url tells social platforms which URL to attribute shares to. Since the Open Graph spec itself treats og:url as required (unlike og:description, which it lists as optional; see seo/og-description), the severity follows the spec’s own required/optional split.

How to fix

<svelte:head>
  <meta property="og:url" content="https://example.com/this-page" />
</svelte:head>

Mode differences

Source analysis (the CLI, the dashboard’s static baseline) composes each route’s <head> from <svelte:head> in the page and its layout chain, followed into repo-local components, plus the known meta components (svelte-meta-tags, svelte-seo) and any you declare in metaComponents. A value it cannot read literally ({data.title}) is dynamic, judged by treatDynamicAs. Rendered analysis (the Vite plugin’s build pass, a route you visit in the dashboard) reads the shipped <head>, where every value is literal and treatDynamicAs does not apply; the build pass covers prerendered routes only. When the two disagree, trust the rendered result.

Disabling

Record existing findings in the suppressions file (npx svelte-vitals --update-suppressions), scope the rule per route or path with overrides, or turn it off:

export default {
  rules: {
    'seo/og-url': 'off'
  }
};
