Mintlify automatically handles many SEO best practices, including:
  • Meta tag generation
  • Sitemap and robots.txt file generation
  • Semantic HTML structure
  • Mobile optimization
You can fully customize your site’s meta tags by adding the metatags field to your docs.json or a page’s frontmatter.

​
Global meta tags

To set default meta tags for all pages, add the metatags field to your docs.json. 
"seo": {
    "metatags": {
        "og:image": "link to your default meta tag image"
    }
}

​
Page-specific meta tags

To set page-specific meta tags, add them to a page’s frontmatter. 
---
title: "Your example page title"
"og:image": "link to your meta tag image"
---
Meta tags with colons must be wrapped in quotes.

​
Common meta tags reference

Below is a comprehensive list of meta tags you can add to your docs.json. These meta tags help improve your site’s SEO, social sharing, and browser compatibility.
The og:image adds a background image that Mintlify automatically overlays with your logo, page title, and description when generating social media previews.
You can preview how your meta tags will appear on different platforms using metatags.io.

​
Sitemaps and robots.txt files

Mintlify automatically generates a sitemap.xml file and a robots.txt file. You can view your sitemap by appending /sitemap.xml to your documentation site’s URL. Only pages included in your docs.json are included by default. To include hidden links, add seo.indexing to your docs.json: 
"seo": {
    "indexing": all
}

​
Custom sitemaps and robots.txt files

To add a custom sitemap.xml or robots.txt file, create a sitemap.xml or robots.txt file at the root of your project. Adding a custom file will override the automatically generated file of the same name. If you delete a custom file, the default file will be used again.

​
Disabling indexing

If you want to stop a page from being indexed by search engines, you can include the following in the frontmatter of your page: 
---
noindex: true
---
You can also specify noindex for all pages in your docs by setting the metatags.robots field to "noindex" in your docs.json: 
"seo": {
    "metatags": {
      "robots": "noindex"
    }
  }
