# SEO and Meta
|
|
|
|
Out-of-the-box, Nuxt provides good default values for `charset` and `viewport` meta tags, but you can override these if you need to, as well as customize other meta tags for your site in several different ways.

## `useHead` Composable
|
|
|
|
Within your `setup` function, you can call `useHead` with an object of meta properties with keys corresponding to meta tags: `title`, `titleTemplate`, `base`, `script`, `noscript`, `style`, `meta` and `link`, as well as `htmlAttrs` and `bodyAttrs`. There are also two shorthand properties, `charset` and `viewport`, which set the corresponding meta tags. Alternatively, you can pass a function returning the object for reactive metadata.
|
|
|
|
For example:
|
|
|
|
```vue
|
|
<script setup>
|
|
useHead({
|
|
title: 'My App',
|
|
// or, instead:
|
|
// titleTemplate: (title) => `My App - ${title}`,
|
|
viewport: 'width=device-width, initial-scale=1, maximum-scale=1',
|
|
charset: 'utf-8',
|
|
meta: [
|
|
{ name: 'description', content: 'My amazing site.' }
|
|
],
|
|
bodyAttrs: {
|
|
class: 'test'
|
|
}
|
|
})
|
|
</script>
|
|
```

## Title Templates
|
|
|
|
You can use the `titleTemplate` option to provide a dynamic template for customizing the title of your site, for example, by adding the name of your site to the title of every page.
|
|
|
|
The `titleTemplate` can either be a string, where `%s` is replaced with the title, or a function. If you want to use a function (for full control), then this cannot be set in your `nuxt.config`, and it is recommended instead to set it within your `app.vue` file, where it will apply to all pages on your site:
|
|
|
|
```vue [app.vue]
|
|
<script setup>
|
|
useHead({
|
|
titleTemplate: (titleChunk) => {
|
|
return titleChunk ? `${titleChunk} - Site Title` : 'Site Title';
|
|
}
|
|
})
|
|
</script>
|
|
```
|
|
|
|
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
|
|
|
|
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>`, `<NoScript>`, `<Style>`, `<Meta>`, `<Link>`, `<Body>`, `<Html>` and `<Head>` components so that you can interact directly with your metadata within your component's template.
|
|
|
|
Because these component names match native HTML elements, it is very important that they are capitalized in the template.
|
|
|
|
`<Head>` and `<Body>` can accept nested meta tags (for aesthetic reasons) but this has no effect on _where_ the nested meta tags are rendered in the final HTML.
|
|
|
|
For example:
|
|
|
|
<!-- @case-police-ignore html -->
|
|
|
|
```vue{}[app.vue]
|
|
<script setup>
|
|
const title = ref('Hello World')
|
|
</script>
|
|
|
|
<template>
|
|
<div>
|
|
<Head>
|
|
<Title>{{ title }}</Title>
|
|
<Meta name="description" :content="title" />
|
|
<Style type="text/css" children="body { background-color: green; }" />
|
|
</Head>
|
|
|
|
<h1>{{ title }}</h1>
|
|
</div>
|
|
</template>
|
|
```
|
|
|
|
## Example: Usage With `definePageMeta`
|
|
|
|
Within your `pages/` directory, you can use `definePageMeta` along with `useHead` to set metadata based on the current route.
|
|
|
|
For example, you can first set the current page title (this is extracted at build time via a macro, so it can't be set dynamically):
|
|
|
|
```vue{}[pages/some-page.vue]
|
|
<script setup>
|
|
definePageMeta({
|
|
title: 'Some Page'
|
|
})
|
|
</script>
|
|
```
|
|
|
|
And then in your layout file, you might use the route's metadata you have previously set:
|
|
|
|
```vue{}[layouts/default.vue]
|
|
<script setup>
|
|
const route = useRoute()
|
|
|
|
useHead({
|
|
meta: [{ name: 'og:title', content: `App Name - ${route.meta.title}` }]
|
|
})
|
|
</script>
|
|
```
