A snippet of code packed in a plugin to render the WordPress RSS widget as a shortcode.
This allows you to display external or related content on its own page.
In combination with Yahoo! Pipes, or another RSS magic service, you can create nice collections of articles for your readers on a separate page.
This plugin does not create WordPress posts from feed items.

FeedWordPress is an Atom/RSS aggregator for WordPress. It syndicates content from feeds that you choose into your WordPress weblog, and then the content it syndicates appears as a series of special posts in your WordPress posts database. If you syndicate several feeds then you can use WordPress’s posts database and templating engine as the back-end of an aggregation (“planet”) website. It was developed, originally, as a utility/hobby project, because I needed a more flexible replacement for <a href="https://web.archive.org/web/20051029095046/http://www.planetplanet.org/" rel="nofollow ugc">Planet</a> for aggregator sites that I administered.
FeedWordPress is designed with flexibility, ease of use, and ease of configuration in mind. You’ll need a working installation of WordPress (version <a href="https://codex.wordpress.org/Version_4.5" rel="nofollow ugc">4.5</a> or later), and it helps to have SFTP or FTP access to your web host. The ability to create cron jobs on your web host is helpful but not required.
<h3>Using and Customizing FeedWordPress</h3>
FeedWordPress has many options which can be accessed through the WordPress Dashboard, and a lot of functionality accessible programmatically through WordPress templates or plugins. For further documentation of the ins and outs, see the documentation at the <a href="http://feedwordpress.radgeek.com/" rel="nofollow ugc">FeedWordPress project homepage</a>.

FeedWordPress

I've been using FWP for years. I used to have several sites that relied on it for aggregating ebay stuff. However, on shared hosting, and with MANY syndicated sources, my sites often got banned for hogging the server.
The "problem" is that FWP is so excellent at what it does, I got carried away with the number of sources. 
I've been using a different aggregator for a while, but it doesn't have the flexibility of FWP: setting Category, Tags and custom fields per feed is awesome.  
Hence, I've come back to using FWP, but not using the scheduling features, and taking it easy on the number of sources.  
If you are NOT on a shared server, just ignore my comments and "fill yer boots". 

Excellent! Be careful on shared hosting, though..

I struggled with multiple RSS aggregation plugins, all of which were paid subscription plugins. I had already paid for one and after hours, I could not make it import enclosures to PowerPress. FeedWordpress took about 5 minutes to set up and worked perfectly. It also had the feature to all for reimportation of items which the paid plugin lacked. This free plugin is in every way better than the commercial alternatives.

Simple Install and Works Great

Have used FeedWP for multiple projects over the decades, for monitoring news on specific topics. Works flawlessly, and offers many valuable options. A well-designed workhorse.

Excellent and dependable.

FeedWordPress syndicates content from feeds you choose into your WordPress weblog.
