<link rel="alternate" type="application/rss+xml" title="Blog Posts RSS Feed" href="http://yourdomain.com/feed" />
I dont know if this is the best way but I normally ping the sites where I have good backlinks. I have heard pinging your sites too often is not good and hence i refrain from doing it.
Pinging sites linking to your site does give me a boost in traffic for a few days.
Let me know what you people think about this..
