# Search Engine Optimization

<Accordion title="Supported Meta Tags">
  * og:site\_name
  * og:title
  * og:description
  * og:url
  * og:image
  * og:locale
  * og:logo
  * article:publisher

  * twitter:description

</Accordion>

## Default meta tags

You can set default meta tags by adding the `metadata` field to your `mint.json`.

```json
"metadata": {
    "og:image": "link to your default meta tag image"
}
```

## Changing meta tags on one page

Add your meta tags to the page's metadata like so:

```md
---
title: 'Your Example Page Title'
'og:image': 'link to your meta tag image'
---
```

<Warning>
  Meta tags with colons need to be typed with quotes around them when you put them in the page metadata.
</Warning>

## Sitemaps

Mintlify automatically generates a `sitemap.xml` file and a `robots.txt` file. Simply add `/sitemap.xml` to the end of your website URL to see your sitemap. We recommend submitting the sitemap to search engines for improved SEO.

Only pages included in your `mint.json` are included by default. To include hidden links, add `seo.indexHiddenPages` to your `mint.json`:

```json
"seo": {
    "indexHiddenPages": true
}
```
