my favorite jekyll title & description tags

index.html

<!-- formatted -->
<title>
  {% if page.title %}
    {{ page.title }} | {{ site.title}}
  {% elsif post.title %}
    {{ post.title }} | {{ site.title}}
  {% else %}
    {{ site.title }} | {{ site.description}}
  {% endif %}
</title>

<meta name="description" content="
  {% if page.description %}
    {{ page.description }}
  {% elsif post.description %}
    {{ post.description }}
  {% else %}
    {{ site.description }}
  {% endif %}
">

<!-- condensed -->
<title>{% if page.title %}{{ page.title }} | {{ site.title}}{% elsif post.title %}{{ post.title }} | {{ site.title}}{% else %}{{ site.title }} | {{ site.description}}{% endif %}</title>
<meta name="description" content="{% if page.description %}{{ page.description }}{% else if post.description %}{{ post.description }}{% else %}{{ site.description }}{% endif %}">
