Shout out to the h-feed / h-entry microformat https://microformats.org/wiki/h-feed, sadly underutilized but an extremely easy way to make the web much more syndicable.

They're comprised of standardized CSS class names to be inserted into HTML and enable meaningful scraping. Especially given that more and more sites are produced using JS frameworks, which have a harder time producing XML than older generation PHP and the like, h-feed seems a no-brainer.
