Gets all the links from your posts and adds them to the page.data for that post.

You can then use them in your liquid markup:

<ul>
{% for link in page.links %}
  <li>{{ link.title }} {{ link.cleaner_href }} {{ link.href }}</li>
{% endfor %}
</ul>

The title is the text that appears inside the anchor tag and the cleaner_href is the href with campaign utm and Chrome text fragment cruft removed, which can make a url human-unreadable.
