Welcome to the Q&A Forum

Yeah, that could make sense! I haven't been able to replicate it so definitely a weird example. Thanks!

The responses here are great. I think you should have all of the resources you need now. Although it doesn't show domains that link to you, I also like to see the ones that are hosted on the same server, which you can find here: https://viewdns.info/reverseip/ . I agree that Google Search Console and Moz are great places to start.
