Sometimes, bloggers or webmasters may want to display and show contents from other blogs, and the most easy way to do so is by fetching and importing the RSS feed from external sites and display the RSS feed items on own WordPress blog. Doing so will introduce readers to related external contents, or promote other relevant sites. There are plenty of ways or methods to fetch and display the feed items or contents, or aggregate the Atom or RSS feeed, either by using plugins, external services or using PHP scripts.
