What it does

Jekyll SEO Tag adds the following meta tags to your site:

While you could theoretically add the necessary metadata tags yourself, Jekyll SEO Tag provides a battle-tested template of crowdsourced best-practices.

What it doesn't do

Jekyll SEO tag is designed to output machine-readable metadata for search engines and social networks to index and display. If you're looking for something to analyze your Jekyll site's structure and content (e.g., more traditional SEO optimization), take a look at The Jekyll SEO Gem.

Jekyll SEO tag isn't designed to accommodate every possible use case. It should work for most site out of the box and without a laundry list of configuration options that serve only to confuse most users.


  1. Add the following to your site's Gemfile:
  gem 'jekyll-seo-tag'
  1. Add the following to your site's _config.yml:
    - jekyll-seo-tag
  1. Add the following right before </head> in your site's template(s):
    {% seo %}


The SEO tag will respect any of the following if included in your site's _config.yml (and simply not include them if they're not defined):

  • title - Your site's title (e.g., Ben's awesome site, The GitHub Blog, etc.)
  • description - A short description (e.g., A blog dedicated to reviewing cat gifs)
  • url - The full URL to your site. Note: site.github.url will be used by default.
  • twitter:username - The site's Twitter handle. You'll want to describe it like so:
    username: benbalter
  • logo - Relative URL to a site-wide logo (e.g., assets/your-company-logo.png)
  • social - For specifying social profiles. The following properties are available:
    • type - Either person or organization (defaults to person)
    • name - If the user or organization name differs from the site's name
    • links - An array of links to social media profiles.

The SEO tag will respect the following YAML front matter if included in a post, page, or document:

  • title - The title of the post, page, or document
  • description - A short description of the page's content
  • image - The absolute URL to an image that should be associated with the post, page, or document
  • author - The username of the post, page, or document author
