So, yes, “url” is optional,

The itemprop="url" helps google to combine multiple Comment blocks on different URLs belonging to the same topic.

@rrit

Important: the itemprop url must point to the first page of the topic in crawler view:

• e.g. https://example.org/t/topic-title/1234
• not https://example.org/t/topic-title/1234?page=2

See DiscussionForumPosting → Recommended properties → url

url: The canonical URL of the discussion. In multi-page threads, set this property to th first page URL. For a single discussion, this is usually the current URL.
