hola. I've been aware SEO for years due to my day job as a photographer. My first site was PR5 back in the day and very strong (a tutorial went viral and was linked EVERYWHERE). I've had to re-brand twice due to partner issues and haven't had as much time to organically build links to my latest website. For a long time, I've wanted to do more gear reviews / comparisons etc in my photography niche, but having too many on my site felt like it took away from my main objective of selling my own photography. So I'm building an amazon affiliate site to do all of my gear reviews / tutorials / comparisons etc. I also decided to build a PBN and am in the early stages. Going to start w/ 15 domains. My original goal was to just link to my photography site from the PBN. Would it be okay to also link to my money site from all of the 15 domains? from a few of them? should I build separate PBN's? Thanks!
