title: seo/twitter-card ยท Twitter Card
description: Pages should declare a twitter:card for rich sharing on X/Twitter.
---
**Severity:** info
## What it checks
Every route should include a `` tag (own or inherited). A missing or empty tag is flagged.
## Why it matters
twitter:card selects how the page renders when shared on X/Twitter; without it the platform shows a basic link. (Open Graph tags act as fallbacks for the card's title and image.)
## How to fix
```svelte
```
## Mode differences
**Source analysis** (the CLI, the dashboard's static baseline) composes each route's `` from `` 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 ``, 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:
```js svelte-vitals.config.js
export default {
rules: {
'seo/twitter-card': 'off'
}
};
```
