If you want to automatically post (autopost) content from one site to another this can easily be done with WordPress and RSS feeds.
The original site can be a WordPress site, non-WordPress site or any other web-enabled app that can produce an RSS feed. That’s the key, the RSS/Atom feed will be used as the source for your imported content.
Simply get WP RSS Aggregator and Feed to Post, then follow the instructions below to have your content streamed automatically into your site.

AutoPost from one site to another with WordPress and the WP RSS Aggregator plugin.Get the Plugin
The first thing we need to do is to add a new feed source, so head over to RSS Aggregator > Add New in your WordPress dashboard (wp-admin). Then enter the feed URL of the site you want to extract feeds from. You can also set a limit of items to be imported during every update.
Once we have that source set up, you can continue adding more sources. You have all the flexibility you could want when importing content with the Feed to Post add-on.
You can then display the posts within your site using your theme or also by building custom views with plugins such as WP Views if you are not a developer yourself and don’t want to mess with any theme code.
