## What it checks
For each static `
```
## 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`. It judges only a **literal** value; it never examines a dynamic one. **Rendered analysis** (the Vite plugin's build pass, a route you visit in the dashboard) reads the shipped ``, where every value is literal; 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/json-ld-validity': 'off'
}
};
```
