Choose Article, NewsArticle, or BlogPosting to match the content. Identify the actual author and publication or modification dates. Put the author's name in author.name and a page identifying that author in author.url. Do not add credentials to the name or identify someone who did not write the article as its author.
Google's Article documentation recommends applicable properties without setting universal required properties. Discover does not require special tags or structured data. Valid Article markup alone is not evidence of Discover exposure or increased credibility.
