You can set up a custom alert in Google Analytics to notify you of when these referrals (I still don't know how the correct spelling, thanks HTML) occur. I think the question has been discussed on here before, at some point, the manual team review your site and assign you a score, so how much of the last mile for authority sites, particularly in YMYL niches, is based on this manual process?
Appen back on my site again today... I do have some key pages that I hardcode(with dynamic updates) as much schema as a I can (legit, not spammy), so maybe they are interested in that. I rolled out some new rating stuff last week.
