No, you must put real values (not a zero) for ratings. Thus, only add an aggregate rating if you have one. The key fields are:

  • bestRating: The highest value allowed in this rating system. If bestRating is omitted, 5 is assumed.
  • ratingValue: The rating for the content.
  • worstRating:The lowest value allowed in this rating system. If worstRating is omitted, 1 is assumed.
