Hi Sussane
It's really easy to use RRS Feed and it's powerful to generate traffic to your blog,
1. You have to subscribe with RSS submission directories and they are a lot, choose some of them.
2. You have to submit your feed content to all directories including the link of this content.
3. You put add feed button to all RRS directories you use in your blog to allow anybody to bookmark your page, vote it, or send it to others

The powerful thing that you generate traffic to your blog from these directories because these directories are the best places to find new contents and they save the searcher’s time.
Good Luck
