Google has said that by adding article structured data to your news and article pages, you can enhance its appearance in search results. This means your article could appear in a top stories carousel, visual stories or it could have a larger than usual image to distinguish it from other search results. 

Using this mark-up could mean more exposure and traffic for your site in Google Search.
