Webmentions are the modern standard that evolved out of trackbacks and pingbacks.

If you’ve written a blog post that references or links to another blog post, Webmention is the standard way to notify them.

An example use case for Webmentions is blog comments. A blog may publish a post which is a reply to another blog, then send a Webmention to notify them. The author of the blog post being replied to could choose to display the comment below their post.
