RSS, or real simple syndication, is one of the best and oldest ways to gain SEO, or search engine optimization for a website. Users will find good RSS feeds that they like or fits with the content of their site. The new information these site sends out will be delivered directly to the user. The best RSS readers will organize all the subscriptions a user has followed and update it regularly.
Say, a person subscribes to a Google news reader, the person will then be able to directly see all the news that the RSS Google news puts through. Best RSS feed readers will check the feeds the user is subscribed to and updates them every time something is put out.
Best of all, best RSS readers are free for any user. Sometimes SEO costs money, but this does not. Anyone can access it on a computer for the benefit of making it easier to find the information you want. Finding an RSS feed reader is as easy as making a simple Google search to find the best RSS readers for you.
