Anybody ploease tell me about Rss feed.

The RSS feed is like an email subscription only much more convenient. Whenever you make a post your RSS feed updates and includes the post. Your readers can subscribe to your feed and when they do they will be informed automatically when you write a new post and they can read it directly from the feed (in most cases)!

RSS is a way to promote your Blog, it's generate traffic, the rss feed Bring Subscribers to your Blog, anytime you Write a new Posts , the RSS feed Spread it to Subscribers and that's all. it's a important tool now day if you take a good profite of it and know how it's work. Goodluck!
