What it is

Authors of blog posts hosted on the Wordpress.com platform link to Registered Content Items. The Wordpress.com Agent monitors the service to look for these links.

What it does

  • Scans every article Landing Page domain in the domain-list, including doi.org
  • Makes a query to the Wordpress.com API for blog posts that mentioned that domain.
  • For each result, visits the blog post and attempts to extract links from the HTML of the blog post.
