Hi, I have few questions about PBN best practice, 1. lots of guides suggests to block crawlers that arent google, to prevent sniffing. but on the other hand they mention that blocking crawlers is a foot print. So all in all, is it worth the advantages, to give google a footprint to recognize PBNs very easily if one update will start checking that? 2. when buying an expired domain name, I assume that big part of its old backlinks were to internal pages on the site and not just the home page, what is the best practice in order to try and keep the site in a good health? how to forward all broken links to the home page or whatever is the suggestion? the default behavior is showing a broken link page, I'm not sure if that's the best practice. Thanks!
