--- id: head-metadata title: Head Metadata description: Declaring page-specific head metadata through MDX slug: /markdown-features/head-metadata --- # Head Metadata Docusaurus automatically sets useful page metadata in ``, `` and `` for you. It is possible to add extra metadata (or override existing ones) by using the `` tag in Markdown files: ```md title="markdown-features-head-metadata.mdx" --- id: head-metadata title: Head Metadata --- Head Metadata customized title! # Head Metadata My text ``` ```mdx-code-block Head Metadata customized title! ``` :::tip This `` declaration has been added to the current Markdown doc, as a demo. Open your browser DevTools and check how this page's metadata have been affected. ::: :::tip **You don't always need this for typical SEO needs.** Content plugins (e.g. docs and blog) provide front matter options like `description`, `keywords`, and `image`, which will be automatically applied to both `description` and `og:description`, while you would have to manually declare two metadata tags when using the `` tag. ::: :::note This feature is built on top of the Docusaurus [``](./../../docusaurus-core.md#head) component.
