RSS Definition:

RSS (most commonly expanded as Really Simple Syndication) is a family of web feed formats used to publish frequently updated works—such as blog entries, news headlines, audio, and video—in a standardized format. An RSS document (which is called a “feed”, “web feed”, or “channel”) includes full or summarized text, plus metadata such as publishing dates and authorship. Web feeds benefit publishers by letting them syndicate content automatically. They benefit readers who want to subscribe to timely updates from favored websites or to aggregate feeds from many sites into one place. RSS feeds can be read using software called an “RSS reader”, “feed reader”, or “aggregator”, which can be web-based, desktop-based, or mobile-device-based.”

RSS feeds have long been a staple of content distribution for website owners. At the beginning of any quality SEO campaign, it is very helpful to create a net of distribution channels throughout the internet via RSS feeds- making it easier for others to connect to quality articles and content. Recently, I’ve started using a list, created by MasterNewMedia.org, of 55 RSS directories. I like that the list is kept up to date and includes helpful summaries of each source. Take a look at my overview of this helpful source. 
 

  
If you have any lists that you recommend, or automation tools for distributing PR and Blog RSS feeds, I’d love to hear your suggestions. I would be happy to try any of these helpful resources and post a review.
