Provide global meta attributes for the entire site through the [site configuration](./configuration.mdx#site-metadata). The metadata will all be rendered in the HTML `<head>` using the key-value pairs as the prop name and value. The `metadata` attribute is a convenient shortcut to declare `<meta>` tags, but it is also possible to inject arbitrary tags in `<head>` with the `headTags` attribute.
```js title="docusaurus.config.js"
module.exports = {
themeConfig: {
metadata: [{name: 'keywords', content: 'cooking, blog'}],
// This would become <meta name="keywords" content="cooking, blog"> in the generated HTML
// Declare some <meta> tags
metadata: [
{name: 'keywords', content: 'cooking, blog'},
{name: 'twitter:card', content: 'summary_large_image'},

headTags: [
// Declare a <link> preconnect tag

tagName: 'link',
attributes: {
rel: 'preconnect',
