I use some of the plugins from this plugin suite: https://wordpress.org/plugins/indieweb/

I don’t use all of them, but I mainly use the indieauth, syndication, and webmentions.

Webmentions & syndication are how I get the “X user liked this” and stuff, it’s webmention display. I use brid.gy and connect it to my microblog fediverse account and it checks the replies to the syndicated post I make and pings it to the blog via webmentions. It’s pretty solid. If you need any help setting it up I’m here though.
