The articleBody
property is for the "actual body of the article".
What is or isn’t part of the article body is the author’s choice, of course. If you think that an advertisement or a gallery is part of your article, include it. Otherwise omit it.
Note that this property expects a Text
value. If you follow this advice, you can’t include HTML (it would be interpreted as textit would be interpreted as text), so you can’t have images as part of its value.
