Y’all can check your Google Search Console report, but when I go to https://search.google.com/search-console/r/discussion-forum and check my forum, I see this:
Why items are invalid:
- Either “text”, “image”, or “video” should be specified
- Missing field “datePublished”
- Missing field “author”
Improve item appearance
- Missing field “url”
- Missing field “text” (in “comment”)
So there does appear to be more work to do here.
