Backlinks still do play a role in voice believe it or not. It’s just not as prominent as a local or a traditional SEO.
I mean SEO, god has that ever changed. In the last ten years, I mean you could throw a couple keywords up on an H1 in an URL. It was called SERPing 10 years ago. You could easily take over any industry with a simple keyword injection throw a couple back links up and that was SEO, and now it’s so hard and that’s the truth.
