Hi, I read somewhere that if you redirect old 404 pages from your PBN to the root domain, it's considered a "soft 404", and doesn't pass link juice. I know a lot of pbn builders who use wayback machine to rebuild the original content and they say it preserves the link juice. The most convincing argument I've found for someone to rebuild the old site is to hide the pbn. It's not always possible, but if you can do it you can pass manual reviews with flying colors. But the link juice I'm not too sure about and I just want to open this up for discussion. What are your thoughts, guys?
