`useSeoMeta()` accepts SEO metadata as a typed flat object.

```ts
useSeoMeta({
  title: 'Page Title',
  description: 'Page description for search engines',
  ogTitle: 'Social Share Title',
  ogDescription: 'Description for social media',
  ogImage: 'https://example.com/og-image.jpg'
})
```

Unhead chooses `name` or `property` for each field. Because the API accepts meta values rather than raw HTML, it does not expose `innerHTML` or arbitrary tag attributes.

## Basic Usage

```ts
import { useSeoMeta } from '@unhead/dynamic-import'

useSeoMeta({
  title: 'About',
  description: 'My about page',
  ogDescription: 'Still about my about page',
  ogTitle: 'About',
  ogImage: 'https://example.com/image.png',
  twitterCard: 'summary_large_image',
})
```

## Examples

### Complete SEO Setup

```ts
import { useSeoMeta } from '@unhead/dynamic-import'

useSeoMeta({
  // Basic SEO
  title: 'Product Name - Your Brand',
  description: 'Detailed product description optimized for search engines.',

  // Open Graph
  ogTitle: 'Product Name - Your Brand',
  ogDescription: 'Engaging description for social media shares.',
  ogImage: 'https://example.com/product-social.jpg',
  ogUrl: 'https://example.com/products/my-product',
  ogType: 'website',
  ogSiteName: 'Your Brand',

  // Twitter
  twitterCard: 'summary_large_image',
})
```

### Dynamic Meta Tags

<framework-code>
<template v-slot:vue="">

```ts
import { useSeoMeta } from '@unhead/dynamic-import'
import { computed, ref } from 'vue'

const product = ref({
  name: 'Travel Keyboard',
  description: 'A compact mechanical keyboard with hot-swappable switches',
  image: 'https://example.com/image.png'
})

useSeoMeta({
  title: computed(() => `${product.value.name} - Your Brand`),
  description: computed(() => product.value.description),
  ogImage: computed(() => product.value.image),
})
```

</template>

<template v-slot:react="">

```tsx
import { useSeoMeta } from '@unhead/dynamic-import'
import { useState } from 'react'

function ProductPage() {
  const [product] = useState({
    name: 'Travel Keyboard',
    description: 'A compact mechanical keyboard with hot-swappable switches',
    image: 'https://example.com/image.png'
  })

  useSeoMeta({
    title: () => `${product.name} - Your Brand`,
    description: () => product.description,
    ogImage: () => product.image,
  })

  return <div>Product Page</div>
}
```

</template>

<template v-slot:solid="">

```tsx
import { useSeoMeta } from '@unhead/dynamic-import'
import { createSignal } from 'solid-js'

function ProductPage() {
  const [product] = createSignal({
    name: 'Travel Keyboard',
    description: 'A compact mechanical keyboard with hot-swappable switches',
    image: 'https://example.com/image.png'
  })

  useSeoMeta({
    title: () => `${product().name} - Your Brand`,
    description: () => product().description,
    ogImage: () => product().image,
  })

  return <div>Product Page</div>
}
```

</template>
</framework-code>

## How it works

Unhead's flat-meta plugin converts each camel-cased key to the appropriate `<meta>` tag and chooses `name`, `property`, or `http-equiv` according to its built-in schema. Packed objects such as `robots` are expanded into their serialized content values.

## API Reference

### Input

A flat object with keys representing different meta tags. All properties are optional.

### Return Value

The composable returns an `ActiveHeadEntry<UseSeoMetaInput>` with `patch()` and `dispose()` methods. Framework integrations also update the entry when their reactive input changes.

## Common Mistakes

### Omitting useful Open Graph tags

The [Open Graph protocol](https://ogp.me/) defines `og:title`, `og:type`, `og:image`, and `og:url` as its basic fields. Image dimensions are optional structured properties, while `og:image:alt` should accompany an image.

```ts
// Minimal preview metadata
useSeoMeta({
  ogTitle: 'My Page',
  ogDescription: 'Description'
})

// Richer preview metadata
useSeoMeta({
  ogTitle: 'My Page',
  ogDescription: 'Description',
  ogImage: 'https://example.com/og.jpg',
  ogUrl: 'https://example.com/page',
  ogType: 'website',
})
```

### Reusing an unsuitable preview image

```ts
// A small icon is unlikely to work well as a large social preview
useSeoMeta({
  twitterCard: 'summary_large_image',
  ogImage: 'https://example.com/small-icon.png',
})

// Supply a purpose-built social image and its dimensions
useSeoMeta({
  twitterCard: 'summary_large_image',
  ogImage: {
    url: 'https://example.com/social-card.jpg',
    width: 1200,
    height: 630,
    alt: 'Product preview',
  },
})
```

### Duplicating content unnecessarily

```ts
// Repeated values are harder to keep in sync
useSeoMeta({
  description: 'My description',
  ogDescription: 'My description',
})

// Or install InferSeoMetaPlugin and let it generate matching fallbacks
useSeoMeta({
  description: 'SEO-optimized description for search',
})
```

## Common Questions

### What's the difference between useSeoMeta and useHead?

`useSeoMeta()` provides a flat, typed API for SEO fields. `useHead()` accepts all supported head tags and entry options.

### Do I need both title and ogTitle?

The `title` sets the `<title>` tag. `ogTitle` sets `og:title` for social sharing. They can differ because a preview card and a browser tab have different space and context.
