Can No-Listed Pages With Canonical To New Page Cross Google Alerts?

Kenichi Suzuki asked Google’s John Mueller an SEO question that got an interesting response. The question was “I’m curious about this thread. If page A has noindex and rel=canonical pointing to Page B, are the signals of A transferred to B?” John replied, “I don’t think that’s defined.”

Here are those tweets:

I don’t think that’s defined.

You’d think the answer would be something Google has defined? I mean, you’d think a noindex on page A that has a canonical to page B, wouldn’t pass signals? I mean, Google doesn’t have to index the page to see the canonical and then it also has to index the page to see the noindex. But still, wouldn’t that cancel out everything?

I guess it depends on other factors. Maybe sometimes google will pass the signals on those pages and sometimes not?
