So I was checking a competitor's backlinks and using tools like Ahrefs, Majestic, Monitor Backlinks etc. I couldn't find anything suspicious or interesting at all: about 15-20 backlinks with poor anchor text on 12-15 domains. However, he's been ranking number 1 or number 2 for most keywords in a competitive area. I now just installed SEO Spyglass and the software shows 2500 backlinks on 194 domains. But the thing is that most of these backlinks do not exist. The page does exist but when I check it there's no mention of the competitor. Plus, it doesn't make sense, one link is about photography, the other one is about fashion, the next one is about machinery etc. while he is in the computing area. Some websites are legit businesses so they wouldn't have any interest in putting a backlink. There's even a backlink from a French city website... like wtf? Does anyone know what is happening?
