Sometimes you’ll only want to grab certain articles from a news source.
For example, you might own a website that’s dedicate to Apple iPhone news and one of your news sources is Tech Crunch.
In this instance, you wouldn’t want your site to crawl the news from Tech Crunch that isn’t related to the iPhone.
With WP News Aggregator, you can tell the plugin to ‘only include articles containing these keywords’ and to ‘exclude articles containing these keywords.
This gives you a huge amount of flexibility in determining which articles make it through to your aggregator.
