Here is a handy plugin that lets you grab content from any site and add it to your own. The WP Content Crawler Plugin can be used to collect news and other updates from your favorite sources. You can use it with WooCommerce to add products from top shopping sites.
This plugin lets you add sites and post categories, configure CSS selectors, and put crawling on schedule. The last crawled posts are displayed in the dashboard. The test button is quite handy as you can make sure your rules work. With advanced HTML manipulation, you can change element attributes, find/replace elements, and do a whole lot more.
WP Content Crawler can be used to save many posts at the same time. It is smart enough to check for duplicate posts and fix character encoding problems. turgutsaricam is the coder behind this plugin.
