Create Breadcrumb in Jekyll

Create Breadcrumb in Jekyll

Breadcrumb is a technique to show the level of your page so the user can browse any level directly, even from the Google search page. Also, the breadcrumb snippet must be put in the head tag of the HTML if you want to use the JSON-LD format.

My blog uses the URL pattern - <base>/<category>/<post>.

For example,


Now the challange is to generate a JSON file based on the page type or level. For my case,

  • Level 1: The home page use layout: default
  • Level 2: The category pages use layout: category
  • Level 3: The post pages use layout: post

In Jekyll, I did not find any easy method to generate breadcrumb. Also it was nowhere written how can I know the level of page. So I had to apply some trick. It was - to use the layout.type variable in _includes/head.html.

Here is my _includes/head.html code that generates breadcrumb snippet (and title also) based on the page type.

{% raw %}

  <meta http-equiv="..." content="...">
  <meta name="..." content="...">
  <script type="application/ld+json">{
  "@context": "",
  "@type": "BreadcrumbList",
  "itemListElement": [
      "@type": "ListItem",
      "position": 1,
      "name": "Home",
      "item": "{{ site.url }}/"
    }{% if layout.type == "category" %},{
      "@type": "ListItem",
      "position": 2,
      "name": "{{ page.title }}",
      "item": "{{ site.url }}/{{ page.title }}"
    }{% endif %}{% if layout.type == "post" %},{
      "@type": "ListItem",
      "position": 2,
      "name": "{{ page.category }}",
      "item": "{{ site.url }}/{{ page.category }}"
      "@type": "ListItem",
      "position": 3,
      "name": "{{ page.title }}",
      "item": "{{ site.url }}/{{ page.url }}"
    }{% endif %}]
    {% if layout.type == "category" %}
        Posts tagged in #{{ page.title }}
    {% else %}
        {{ page.title }}
    {% endif %} | {{ site.title }}</title>

{% endraw %}

The result also looks as I expected.
