SEO and Meta
Improve your Nuxt app's SEO with powerful head config, composables and components.
App Head
Providing an app.head property in your nuxt.config.ts
allows you to customize the head for your entire app.
This method does not allow you to provide reactive data, if you need global reactive data you can use useHead
in app.vue
.
Shortcuts are available to make configuration easier: charset
and viewport
. You can also provide any of the keys listed below in Types.
Defaults
Out-of-the-box, Nuxt provides sane defaults, which you can override if needed.
charset
:utf-8
viewport
:width=device-width, initial-scale=1
Example
export default defineNuxtConfig({ app: { head: { charset: 'utf-16', viewport: 'width=500, initial-scale=1', title: 'My App', meta: [ // <meta name="description" content="My amazing site"> { name: 'description', content: 'My amazing site.' } ], } }})
Composable: useHead
The useHead
composable function allows you to manage your head tags in a programmatic and reactive way,
powered by Unhead.
As with all composables, it can only be used with a components setup
and lifecycle hooks.
Example
<script setup lang="ts">useHead({ title: 'My App', meta: [ { name: 'description', content: 'My amazing site.' } ], bodyAttrs: { class: 'test' }, script: [ { innerHTML: 'console.log(\'Hello world\')' } ]})</script>
Composable: useSeoMeta
and useServerSeoMeta
The useSeoMeta
and useServerSeoMeta
composables let you define your site's SEO meta tags as a flat object with full TypeScript support.
This helps you avoid typos and common mistakes, such as using name
instead of property
.
In most instances, the meta does not need to be reactive as robots will only scan the initial load. So we recommend using useServerSeoMeta
as a performance-focused utility that will not do anything (or return a head
object) on the client.
Example
Simple
<script setup lang="ts">useServerSeoMeta({ title: 'My Amazing Site', ogTitle: 'My Amazing Site', description: 'This is my amazing site, let me tell you all about it.', ogDescription: 'This is my amazing site, let me tell you all about it.', ogImage: 'https://example.com/image.png', twitterCard: 'summary_large_image',})</script>
Reactive
When inserting tags that are reactive, for example, from an API request, you should
use the computed getter syntax, the same as useHead
.
<script setup lang="ts">const data = useFetch(() => $fetch('/api/example'))useServerSeoMeta({ ogTitle: () => `${data.value?.title} - My Site`, description: () => data.value?.description, ogDescription: () => data.value?.description,})</script>
Components
Nuxt provides <Title>
, <Base>
, <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.
Example
<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>
Types
The below is the non-reactive types used for useHead
, app.head
and components.
interface MetaObject { title?: string titleTemplate?: string | ((title?: string) => string) templateParams?: Record<string, string | Record<string, string>> base?: Base link?: Link[] meta?: Meta[] style?: Style[] script?: Script[] noscript?: Noscript[]; htmlAttrs?: HtmlAttributes; bodyAttrs?: BodyAttributes;}
See @unhead/schema for more detailed types.
Features
Reactivity
Reactivity is supported on all properties, as computed, computed getter refs and reactive.
It's recommended to use computed getters (() => {}
) over computed (computed(() => {})
).
<script setup lang="ts">const desc = ref('My amazing site.')useHead({ meta: [ { name: 'description', content: desc } ],})</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:
<script setup lang="ts">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 Tags
You can use the tagPosition: 'bodyClose'
option on applicable tags to append them to the end of the <body>
tag.
For example:
<script setup lang="ts">useHead({ script: [ { src: 'https://third-party-script.com', tagPosition: 'bodyClose' // valid options are: 'head' | 'bodyClose' | 'bodyOpen' } ]})</script>
Examples
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):
<script setup>definePageMeta({ title: 'Some Page'})</script>
And then in your layout file, you might use the route's metadata you have previously set:
<script setup>const route = useRoute()useHead({ meta: [{ property: 'og:title', content: `App Name - ${route.meta.title}` }]})</script>
Add Dynamic Title
In the example below, titleTemplate
is set either as a string with the %s
placeholder or as a function
, which allows greater flexibility in setting the page title dynamically for each route of your Nuxt app:
<script setup>useHead({ // as a string, // where `%s` is replaced with the title titleTemplate: '%s - Site Title', // ... or as a function titleTemplate: (productCategory) => { return productCategory ? `${productCategory} - Site Title` : 'Site Title' }})</script>
nuxt.config
is also used as an alternative way of setting the page title. However, nuxt.config
does not allow the page title to be dynamic. Therefore, it is recommended to use titleTemplate
in the app.vue
file to add a dynamic title, which is then applied to all routes of your Nuxt app.
Add External CSS
The example below shows how you might enable Google Fonts using either the link
property of the useHead
composable or using the <Link>
component:
<script setup lang="ts">useHead({ link: [ { rel: 'preconnect', href: 'https://fonts.googleapis.com' }, { rel: 'stylesheet', href: 'https://fonts.googleapis.com/css2?family=Roboto&display=swap', crossorigin: '' } ]})</script>
