Usage

<script setup lang="ts">
useSeoMeta({
  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>

When inserting tags that are reactive, you should use the computed getter syntax (() => value):

<script setup lang="ts">
const title = ref('My title')

useSeoMeta({
  title,
  description: () => `This is a description for the ${title.value} page`
})
</script>

Parameters

There are over 100 parameters. See the full list of parameters in the source code.

Performance

In most instances, SEO meta tags don't need to be reactive as search engine robots primarily scan the initial page load.

For better performance, you can wrap your useSeoMeta calls in a server-only condition when the meta tags don't need to be reactive:

<script setup lang="ts">
if (import.meta.server) {
  // These meta tags will only be added during server-side rendering
  useSeoMeta({
    robots: 'index, follow',
    description: 'Static description that does not need reactivity',
    ogImage: 'https://example.com/image.png',
    // other static meta tags...
  })
}

const dynamicTitle = ref('My title')
// Only use reactive meta tags outside the condition when necessary
useSeoMeta({
  title: () => dynamicTitle.value,
  ogTitle: () => dynamicTitle.value,
})
</script>

This previously used the useServerSeoMeta composable, but it has been deprecated in favor of this approach.
