Metadata is data (information) about data.

The <meta> tag provides metadata about the HTML document. Metadata will not be displayed on the page, but will be machine parsable.

This metadata can be used by browsers (how to display content or reload page), search engines (keywords), or other web services.

Here’s how your website will look like on Twitter with and without metadata.

No metadata

Correct metadata

Automatically adding social metadata to Hugo sites

After coming across this list I realized theme components was a thing so I’ve extracted my social metadata commit into a separate component for re-use by the community. It’s available on GitHub at msfjarvis/hugo-social-metadata. The README goes through the installation steps so here I will simply cover what the component is actually adding. Here’s the generated metadata for this very post.

<meta property="og:type" content="website" />
<meta name="twitter:card" content="summary_large_image" />
<meta name="twitter:site" content="@msfjarvis" />
<meta
  name="description"
  content="Optimize social media exposure with the right metadata for your site"
/>
<meta name="keywords" content="hugo,webdev,static sites," />
<meta
  property="og:url"
  content="https://msfjarvis.dev/posts/adding-social-metadata-to-your-hugo-sites/"
/>
<meta
  property="og:title"
  content="Adding social metadata to your Hugo sites &middot; Harsh Shandilya"
/>
<meta
  name="twitter:title"
  content="Adding social metadata to your Hugo sites &middot; Harsh Shandilya"
/>
<meta
  name="og:description"
  content="Optimize social media exposure with the right metadata for your site"
/>
<meta
  name="twitter:description"
  content="Optimize social media exposure with the right metadata for your site"
/>
<meta
  name="twitter:url"
  content="https://msfjarvis.dev/posts/adding-social-metadata-to-your-hugo-sites/"
/>
<meta name="twitter:image:src" content="android-chrome-512x512.webp" />
  • og:type - Allowed values are specified at the OpenGraph protocol’s documentation here. I use website to reflect the content I serve.
  • twitter:card - One of summary, summary_large_image, app, or player. summary_large_image indicates that I want to see a social image as well as the description I provide when this is rendered on Twitter.
  • twitter:site - Twitter username of the owner of this website.
  • description - HTML5 tag that describes the content of this page. The content of this can be replicated in og:description and twitter:description to satisfy Facebook and Twitter respectively.
  • og:url and twitter:url - Permalink to the content that this page is for. You can use this to provide a link with tracking related metadata to track social origins.
  • og:title and twitter:title - Title of the page as you want it to be shown on social media.
  • twitter:image:src - Absolute link to an image that will be used in your Twitter card.
