Now, if you set the title to `My Page` with `useHead` on another page of your site, the title would appear as 'My Page - Site Title' in the browser tab. You could also pass `null` to default to the site title.
## Body Meta Tags
::StabilityEdge{title="Body Meta Tags"}
::
You can use the `body: true` option on the `link` and `script` meta tags to append them to the end of the `<body>` tag.
For example:
```vue
<script setup>
useHead({
script: [
{
src: 'https://third-party-script.com',
body: true
}
]
})
</script>
```
## Meta Components
Nuxt provides `<Title>`, `<Base>`, `<Script>`, `<Style>`, `<Meta>`, `<Link>`, `<Body>`, `<Html>` and `<Head>` components so that you can interact directly with your metadata within your component's template.
