An RSS feed directory is a place where people go to search for content they can run on their sites or subscribe to. You need to submit your rss feeds to the places below to “syndicate” your blog content and get more exposure in those places.
Submission to RSS directories is free for most directories on the list below, just takes time.
Your kid, cousin, or mom would probably submit for you for pretty cheap. Anyone in college in your family? They always need beer money!
