Is this a good strategy to use? Risky? Stupid? I've never tried it but just throwing it out: You go into Moz or Ahrefs and find the pages already linking to your site, preferably with a Dfllow link. Then you go into your PBN and build backlinks to those pages to pump them up with link juice which will pass down to your site. And if you don't have any DFllow backlinks, you just build them use any white hat method out there (i.e. broken link building, email outreach, etc.) Then once others have linked to your site, you build PBN links to those pages linking to you. Thoughts?
