You're right, it wasn't magic. For the brand new WordPress sites, I believe it was due to the default pings that came with the standard WordPress installation.

You're right, it wasn't magic. For the brand new WordPress sites, I believe it was due to the default pings that came with the standard WordPress installation. When you published a new blog post on a fresh WordPress install, WordPress would automatically send out a ping. This feature, called "Ping-o-Matic" is still present in every WordPress installation. You can read more about it here: https://developer.wordpress.org/advanced-administration/wordpress/update-services/ https://developer.wordpress.org/advanced-administration/word... Google likely picked up these pings and quickly indexed the new content. It wasn't an official process, but it worked reliably. The system is still in place, but Google doesn't seem to care anymore.
