@johnmu can you clarify if it is possible for Google to pick up a nofollowed link as the referrer URL in the URL inspection tool as noted at twitter.com/ThisIsSingleton/st

@rustybrick @johnmu
I could be wrong but there is a possibility that since Google treats nofollow tag as a hint and not an instruction, it has crawled this Twitter link (expecting some useful URL is available to crawl) and as a result it is mentioned in the inspection report.

@rustybrick @praveen First off, I suspect folks are once again too focused on links :-)

I don't think it's impossible, but I'd expect it to be rare. Search Console lists links even if they're nofollow, even when the link "value" is zero. It could happen that we know of a page from a source, but only crawl & index it when we know more about a page. Then theoretically, the first mention is there, even if irrelevant, and it's not the reason why the page is indexed.
