Danny Sullivan from Google said on Twitter that BERT does not assign values or scores to specific pages or web sites. It doesn't work that way. BERT is simply (well, not so simply) about Google understanding languages better.
Danny wrote "BERT doesn't assign values to pages. It's just a way for us to better understand language."
