The Double EAT Factor - Backlinks

I had a client email me a couple months ago and say, hey, we lost a lot of traffic to this one page. And it was something very similar where they had been ranking for a couple of terms that they had no business ranking for. So I wouldn't really worry about it too much. It's probably now just where it should have been the whole time. Well, let's spend at least 30 minutes in now. We haven't talked about backlinks. I'd be curious to hear from you if you put any emphasis on backlinks or how you've gone about tackling links again for a two year old site.
