Your Authority Site makes your newest content available for people to subscribe to, so they don't have to actually go to your site to check for new posts. This is called “syndication”.
Your website's content is syndicated in an RSS (Really Simple Syndication) feed, which displays your most recent post titles along with a brief teaser summarizing each of these posts.
Your audience subscribes to your content simply by adding your RSS feed to their feed reader or aggregator so they won't miss any of your posts. They can click on any of the post titles in your feed to arrive at your site and read the entire post.
Your RSS feed is also available for other sites to use if they choose, and for you to post in other places (including some social media sites) to broadcast the links to your newest content.
Syndication benefits both you (the publisher) and the websites displaying your feed. For the other sites, publishing your RSS feed is an effective way of adding greater depth and immediacy to their own sites.
For you, syndication broadcasts exposure to your content far and wide with very little effort on your part. This generates new traffic to your site — making it a simple, free way to advertise your great content!
